How Samsung a differs from s

Video playback

To test the “omnivorous” video playback (including support for various codecs, containers and special features, such as subtitles), we used the most common formats, which make up the bulk of the content available on the Web. Note that it is important for mobile devices to have support for hardware video decoding at the chip level, since it is often impossible to process modern versions using processor cores alone. Also, do not expect a mobile device to decode everything, since the leadership in flexibility belongs to the PC, and no one is going to challenge it.

According to the test results, the Samsung Galaxy S4 mini, unlike its top-end compatriots Galaxy S4 or Galaxy S4 Active, was not equipped with all the necessary decoders, in this case sound ones, which are necessary to fully play most of the most common files on the network. To play them successfully, you will have to resort to using a third-party player. for example, MX Player. True, in it you will first have to change the settings, switching from hardware decoding to software or to a new mode called Hardware (not supported by all smartphones), only then the sound will appear. All results are summarized in a single table.

Format Container, video, sound MX Video Player Native video player
DVDRip AVI, XviD 720 × 400 2200 kbps, MP3AC3 reproduced normally reproduced normally
Web-DL SD AVI, XviD 720 × 400 1400 kbps, MP3AC3 reproduced normally reproduced normally
Web-DL HD MKV, H.264 1280 × 720 3000Kbps, AC3 plays normally with decoder Hardware video plays fine, no sound¹
BDRip 720p MKV, H.264 1280 × 720 4000 Kbps, AC3 plays normally with decoder Hardware the video plays normally, there is no sound¹
BDRip 1080p MKV, H.264 1920 × 1080 8000Kbps, AC3 plays normally with decoder Hardware the video plays normally, there is no sound¹

We did not find the MHL interface in this smartphone (in fact, the MHL adapter in the Samsung version could not even be connected to this smartphone due to the incompatibility of the connectors), so we had to limit ourselves to testing the video output on the device’s own screen using the standard player. To do this, we used a set of test files with an arrow and a rectangle moving one division per frame (see Methodology for testing video playback and display devices. Version 1). Screenshots with a shutter speed of 1 s helped to determine the nature of the frame output of video files with various parameters: the resolution varied (1280 by 720 (720p) and 1920 by 1080 (1080p) pixels) and the frame rate (24, 25, 30, 50 and 60 fps). from). The results of this test are summarized in the table:

File Uniformity Skips
watch-1920×1080-60p.mp4 not reproduced
watch-1920×1080-50p.mp4 badly many
watch-1920×1080-30p.mp4 fine not
watch-1920×1080-25p.mp4 fine not
watch-1920×1080-24p.mp4 fine not
watch-1280×720-60p.mp4 well few
watch-1280×720-50p.mp4 well few
watch-1280×720-30p.mp4 fine not
watch-1280×720-25p.mp4 well not
watch-1280×720-24p.mp4 fine not

Note: if both the “Uniformity” and “Gaps” columns have “green” ratings, this means that when watching movies, most likely, either artifacts caused by uneven interleaving and skipping of frames will not be visible at all, or their number and visibility will not affect the viewing experience. “Red” marks indicate possible problems related to the playback of the corresponding files.

In terms of the frame output criterion, the video playback quality is very good, with the exception of the “heavy” Full HD-files with 50 and 60 fps. However, in any case, the uniform interleaving of frames is a relatively unstable state, since some external and internal background processes lead to periodic failure of the correct interleaving of intervals between frames and even to the skipping of single frames. The brightness range displayed on the screen slightly does not correspond to the original one: in the shadows a pair of gray shades is indistinguishable from black, but the highlights show all the gradations of shades (for video in the range of 16-235). In general, if anyone wants to watch a video on such a small screen, he can do it without any problems.


Samsung Galaxy S4 mini runs on Google Android software platform version 4.2.2. On top of the standard OS interface, the company installed its own user interface called TouchWiz 5.0 (Nature UX). Everything here is arranged in exactly the same way as in the older models of the family, with the exception of some functions. the “Smart-screen” section, for example. From the list of features included in the Smart Screen set of the original Galaxy S4 (smart standby, smart turn, Smart pause, Smart scrolling), only one is left here. smart standby. However, in the case of the Samsung Galaxy S4 mini this function for some reason was even given a different name. “Smart-off”. Although the meaning is the same: the screen stays on while you are looking at it (your eye movements are tracked by the front camera). Gone and “multi-window”. this smartphone can not simultaneously use two applications on one screen. But the set of possibilities for control using movements and gestures (for example, calling the current number is carried out automatically when the device is brought to the ear) remained practically untouched: most of the functions of the “big brother” were preserved in the mini-version.

The Meaning of Samsung Galaxy Series (S,A,J,E)

In the new version of Samsung‘s TouchWiz shell, the main settings menu is divided into four horizontal tabs, this innovation was first discovered in the original Galaxy S4. Now you need to remember in which of these horizontal tabs what is.

Traditionally, the notification panel has a navigation bar at its top for instant access to the most requested functions. The icon strip can be customized to the user’s taste. In general, the implementation of the menu in the notification panel of Samsung is one of the best on the market: what is the value of the brightness adjustment slider just brought here, with which you can quickly and smoothly adjust the brightness to the changed environment, without getting into the depths of the basic settings.

There are a lot of additional applications initially preinstalled. Most of Samsung’s proprietary applications are bundled with a separate account from Google services, so you will have to create an account with the company’s services to use them. The S Travel app (Trip Advisor) provides the user on the road with information about the locality in which he is located, and recommendations designed to help the owner of the smartphone to have an even more vivid experience. S Translator app provides text translation of emails and SMS messages by voice. Samsung ChatOn messenger allows multiple users to chat and transfer media files to each other. Samsung Link function also allows you to share files between different Samsung devices. The Group Play application has been implemented, which allows you to play one track on multiple mobile devices or play multiplayer games. The program is available on a number of Samsung smartphones, including Samsung Galaxy S4, S4 mini, Galaxy Mega 6.3 and 5.8. The convenient WatchOn program, mentioned above, has now also become a standard feature of all Galaxy smartphones equipped with an infrared port.

Samsung Galaxy S4 mini smartphone review

Samsung’s top-of-the-line Galaxy S family is growing. In addition to the main smartphone, which itself is known to have two varieties based on different hardware platforms, the Korean company is also releasing a smaller version called the Samsung Galaxy S4 mini and a rugged version of the Galaxy S4 Active for people with active lifestyles and even a “clean” Google phone Samsung Galaxy S4 Google Play Edition. a variant of the same smartphone, only now with a modified software. By the way, the Koreans are not unique in this: the Taiwanese HTC is going to release its “mini” and “maxi” soon. We have already considered in previous reviews almost all of the listed variations on the Galaxy S theme, and even managed to test the 6.3-inch “monster” that has grown in size called the Galaxy Mega. Now it has come to a scaled-down version of the company’s top smartphone.

That’s right: according to the corporate nomenclature, the model under review not only officially belongs to the Galaxy S line, but is also a smaller version of the Galaxy S4 model specifically, as evidenced by all the brand names and even the name itself. Nevertheless, users looking for a modern smartphone with a powerful flagship hardware, but with a small (normal) screen diagonal, will be disappointed: Samsung Galaxy S4 mini is not only reduced in size, but also greatly reduced in functions and capabilities, completely different. a separate independent model. So, as before, such people still have no alternative (at least, if we take the products of large manufacturers) Apple iPhone with its miniature, by today’s standards, dimensions and top-end filling. well, or look at the “Chinese”, like Xiaomi Mi2S As for the hero of today’s review, the level of its filling turned out to be an order of magnitude lower than that of the company’s flagship. Here is a different SoC, a stripped down set of features of the proprietary user interface, a smaller battery, a simpler camera, and so on. Thus, the buyer should not be deceived: this is not a reduced size Samsung Galaxy S4, but a completely different model in all respects, which only for marketing reasons (read: to increase sales) received from the creators a “foreign” name that she should wear. in general, not at the right time.

Pictures: Samsung Galaxy Mega, Samsung Galaxy S4, Samsung Galaxy S4 mini

By the way, this is not the first attempt of this kind among Koreans: during the triumphant march across the planet of the previous flagship model, the Galaxy S3, Samsung made exactly the same attempt to satisfy all-round user tastes with the release of a smaller version of the Galaxy S3. S3 mini. The model was not in great demand in the market, which is understandable: those who were looking for top-end hardware in a standard rather than a spade-shaped case, having learned that inside a completely different, weaker platform, lost interest and turned away, and those who, in general something, all the same, of course, they chose according to the principle “the more, the better.” There are fears that the same fate will befall the successor of this strange tradition, the Samsung Galaxy S4 mini, because nothing has changed in the manufacturer’s behavior this time: the soul of the big S4 does not glimmer in the small body of the S4 mini, and that says it all.

But our task is not market forecasts, but a scrupulous description of any device that got into our test laboratory, which we will do. Let’s make a reservation right away: we have seen a model that works with only one SIM-card and does not have support for fourth-generation networks (LTE). There are other modifications (for example, the model number that supports LTE is GT-I9195, but it will not be presented on the Russian market); in our case, the model nomenclature number is designated as GT-I9190, and it is about it that our story will go today.

Appearance and usability

Both the Galaxy S4 mini and the Galaxy Mega are externally exact copies of the “standard” Galaxy S4, only with changed dimensions. Apart from the size, in details, even in the smallest, all the new models of the series are absolutely identical in their appearance and arrangement of the cases. The same plastic back covers, metal-like bezels along the side perimeter, the same front panel with a recognizable mechanical hardware middle key, and even the shape and location of speaker grilles, buttons, camera windows, flashes and logos. everything matches perfectly.

And again, the developers from Samsung once again just issued a clone of their own previous product, only changing its dimensions and inserting another board inside.

As for dimensions, the smartphone has become noticeably smaller and lighter than the usual Samsung Galaxy S4, however, in terms of thickness, it even surpasses the original.

  • Samsung Galaxy S4 mini. 124.6 x 61.3 x 8.94mm, 107g
  • Samsung Galaxy S4. 137 x 70 x 7.9mm, 130g
  • Samsung Galaxy Mega. 168 x 88 x 8mm, 199g
  • Sony Xperia V. 129 x 65 x 10.7mm, 120g

The materials of the Samsung Galaxy S4 mini case are only plastic, there is no metal here. The seemingly metallic bezel, which runs along the entire lateral perimeter of the device, is also made not of metal, but of plastic that mimics metal. The material is soft, dents easily remain on it after any impact, we have seen such dents on the rims of both the Galaxy S3 and the Galaxy S4, and now the Galaxy S4 mini.

For obvious reasons, a smartphone of such small dimensions by today’s standards fits comfortably in the palm of any size, even a woman’s, and holds well there. It looks nice and quite stylish, the side bezel and speaker grill shine with chrome, in general the smartphone looks quite neat, although inexpensive and discreet.

The back cover is smooth, glossy, reflective in sunlight and instantly collects fingerprints. The spots instantly cover the entire back wall, so all the time you have to wipe it on your knee, since the area is small. On a smooth surface, a mesh of small scratches forms quickly enough, so cleaners will have to think about purchasing a cover from the very first minutes.

The case of Samsung Galaxy S4 mini is made in a classic candy bar form factor. The back cover here is removable and is fixed with several plastic latches as standard. The battery compartment is hidden under this thin cover: the battery is also removable, and only by removing it, you can get to the memory card and SIM card slots. The structure and location of these slots here differs from that of both the Samsung Galaxy S4 and the Samsung Galaxy S4 Mega: the former have the connectors laid out above the battery, and the latter are assembled one under the other. In the mini-version of the smartphone, under the lid, none of the slots is visible at all. both of them are hidden even deeper, under the battery, so there can be no talk of any hot swapping. Even to get a memory card, you will have to remove the battery, which is not very convenient, but this arrangement is due to a lack of space due to the small size of the device and a rather large battery that takes up most of the internal space of the smartphone.

Both slots are simple in design, not equipped with spring-loaded gripping mechanisms, so inserting and removing both cards requires an awkward pull-up and pull-out style. However, it is at the connectors of the Samsung Galaxy S4 mini that special open places are provided, so that a stuck card can always be pushed with something sharp from the other side. The SIM card is used here in Micro-SIM format, the memory card can expand the built-in memory by 64 GB.

The front panel is completely covered with a protective glass, which hides not only the display, but also the front camera window and the sensor eyes. The hearing speaker is covered with a chrome grille. There are three hardware buttons in a row under the screen: two touch buttons on the sides and one mechanical button in the middle. All buttons are sensitive to touches and presses. no problem with that. The touch buttons have a white soft backlight, the duration of which can be adjusted at the discretion of the owner in the corresponding section of the settings.

The rest of the elements and connectors are habitually scattered along the narrow edges of the device. Both connectors. 3.5 mm headset audio output and Micro-USB. are located at the top and bottom, respectively. The outputs and connectors are not equipped with plugs. the Samsung Galaxy S4 mini is not protected against dust and moisture. The Micro-USB connector here, unfortunately, does not support the mode of connecting external devices using a USB host (OTG), so neither a flash drive nor a keyboard and mouse can be connected to a smartphone. All other members of the Galaxy S family, up to the Galaxy Mega, had excellent OTG support, and it’s strange why the Galaxy S4 mini was cheated. this is just one of those noticeable and significant differences between the mini version and the normal, full-fledged top flagship. Likewise, there is no possibility here to display the image on a monitor or TV via MHL.

It’s good at least that they left an infrared port. it is cut into the upper end of the device and serves, first of all, for working with household appliances as a remote control. Among the software of the smartphone there is a convenient program called WatchOn. it recognizes almost any, even rather old, equipment, easily controllable, for example, with a domestic Beeline TV set-top box or a Phillips TV ten years ago. All settings are already included in the program, you do not need to teach it, so even if the remote control has been lost for a long time, any smartphone from the Galaxy S family equipped with an infrared port will be able to return to its former comfort.

The Samsung Galaxy S4 mini has mechanical keys on the sides of the device: on the left is the volume rocker, on the right is the power / lock button. The keys are made in the same style as the rim of the case. it looks like brushed, roughly sanded metal. The keys are small, but have a fairly soft stroke and are easy to touch.

The device comes to the market in two colors, each of which, traditionally, has been given a romantic name: in this case, it is “White Frost” and “Black Mist”. In our “black” version, the smartphone’s coating is actually not so black. it is, rather, a silver metallic with a black fine mesh applied to it. The front part of the case under the glass is also not black, but dark gray, and it also has a barely noticeable dotted texture that ennobles the overall look of the device. The same applies to the white color version of the Samsung Galaxy S4 mini.


The hardware platform of the Samsung Galaxy S4 mini is based on the Qualcomm Snapdragon 400 SoC. The central processor here has two Krait 300 cores, clocked at 1.7 GHz. It is assisted in graphics processing by the Adreno 305 video processor. everything is exactly the same as the Galaxy Mega, only it has a larger screen and a different resolution. The device provides 1.5 GB of RAM, and the storage available to the user to upload their own files is initially about 5 GB out of the nominally designated 8 GB of internal memory. There is also the possibility of expanding memory due to microSD cards, but connecting external devices via OTG (USB host) is not provided here.

To get an idea of ​​the performance of the Samsung Galaxy S4 mini platform, let’s move on to benchmarks. To begin with, we present the comparative results obtained using the AnTuTu database itself. The performance turned out to be almost half that of the company’s own flagship. here’s the difference between the regular Galaxy S4 and its mini-version. Even one of last season’s oversized public favorites. the Google Nexus 4. was easy on Bosch for performance.

A noticeable lag from the top models of the market can be traced not only in the AnTuTu benchmark, but also in other tests. Such a result is absolutely expected, because while the flagships have long been based on 4-core processors, in the mini-flagship we have a 2-core (albeit with very fast cores). It is logical that in terms of performance, the hardware system of the novelty turned out to be closest to the already forgotten hero of the past. the Sony Xperia V, which was popular at the time (since it is also based on a dual-core processor). All the results obtained by us when testing the Samsung Galaxy S4 mini smartphone in popular tests, we have summarized for convenience in tables, details below.

What is curious: all the results turned out to be almost identical to those of the Samsung Galaxy Mega. another model in the family built on the exact same platform, but with a completely different screen (in size, resolution and even production technology).

As for the benchmarks for evaluating the speed of the javascript engine, the results in them significantly depend on the browser in which the tests are run, so that the comparison can be truly accurate only on the same OS and browsers, and this is not always possible. In the case of devices running on the latest Android operating system, we always try to use Google Chrome, although the results of the same tests in a standard browser (if the manufacturer leaves it in the firmware) often turn out to be better than in Chrome. In browser tests, the results of the Samsung Galaxy S4 mini, by the way, are very good. almost twice better than last year’s Google Nexus 4.

The Samsung Galaxy S4 mini is equipped with a Super AMOLED touchscreen. In numbers, the physical parameters of the smartphone screen are as follows: screen dimensions. 53 × 95 mm, diagonal. 109 mm (4.3 inches), resolution. qHD (960 × 540 pixels), pixel density is 256 ppi.

The brightness of the display has both manual and automatic adjustment, the latter based on the operation of the light sensor. The multitouch technology allows you to simultaneously process up to eight touches. at least as much as we were able to intend with the AnTuTu Tester program. The first five are easily identifiable, and the greater number of simultaneous touches causes difficulties and delays on the screen. The smartphone also has a proximity sensor that locks the screen when you bring the smartphone to your ear.

Alexey Kudryavtsev, editor of the “Monitors” and “Projectors and TV” sections, carried out a detailed examination using measuring devices. Here is his expert opinion on the screen of the test sample.

The smartphone screen is covered with a glass plate with a mirror-smooth surface and, judging by the reflection of bright light sources in it, has a very effective anti-glare filter. On the outer surface of the screen there is a special oleophobic (grease-repellent) coating (in this case, very effective), so fingerprints are removed much easier, and appear at a slower speed than in the case of ordinary glass.

With manual brightness control, its maximum value was about 240 cd / m², minimum. 12 cd / m². Despite the not very high brightness value, even in bright daylight, the smartphone can be used, since it helps out less, in comparison with a typical LCD screen, the reflection of OLED screens from dark areas. You also need to take into account the fact that in this case the smaller the white area on the screen, the lighter it is, that is, the actual maximum brightness of the white areas will almost always be higher than the specified value. The low brightness mode allows you to use your smartphone without any problems even in complete darkness. Automatic brightness control works according to the light sensor (it is located to the right of the front speaker). You can make adjustments to how this function works by moving the setting slider from.5 to 5 units. Further, for three conditions, we give the screen brightness values ​​at three values ​​of this setting. at −5, 0 and 5. In complete darkness in automatic mode, the brightness decreases to 12, 20 and 30 cd / m2, respectively, in an office illuminated with artificial light, the brightness is set to 85, 140 and 225 cd / m², in brightly lit environments (equivalent to daytime outdoors, but not in direct sunlight). increases to 290 cd / m² for all three correction values. In principle, the result of this function is as expected. When the brightness decreases, modulation appears with a frequency of 240 Hz. The figure below shows the brightness versus time for a brightness setting value of 50% (blue curve) and an average brightness at 100% (red curve):

It can be seen that the modulation has a large amplitude, so flickering can be seen at medium brightness values ​​- hardly just looking at the screen, but with fast eye movements or in typical tests for the presence of a stroboscopic effect, flickering is visible with the naked eye. How this affects the comfort of work depends on the individual characteristics of the user.

This smartphone uses the sAMOLED matrix, an active matrix based on organic light-emitting diodes. A full-color image is created using subpixels of three colors. red, green and blue in equal numbers, which is confirmed by a fragment of a micrograph:

The screen has very good viewing angles. white color changes its tint noticeably only when deviated to large angles, black color remains just black at any angle. It is so black that the contrast parameter is simply not applicable in this case. When viewed from a perpendicular view, the uniformity of the white field is very good. The switching of the state of the matrix elements is actually performed instantly, so the response time can be equated to 0. The gamma curve plotted by 32 points did not reveal any blockage in either the highlights or the shadows, and the exponent of the approximating power function is from 2.27 to 2.33 in depending on the selected profile, which is slightly higher than the standard value of 2.2:

On a separate page in the screen settings section, you can select one of four color correction profiles: Dynamic, Standard, Professional Photo and Film. In addition to this, there is a “Optimize display” mode, in which manual selection of a profile is blocked, and the phone, apparently, selects a profile by itself, analyzing the current image. In the case of the Dynamic gamma profile, the curve has a slightly S-shaped character; for the three remaining profiles, it practically does not deviate from the power dependence. Note that the brightness of the image fragments dynamically changes in accordance with the nature of the displayed image. it decreases for light images in general and increases for dark ones. When the Dynamic profile is selected, this effect is a little more pronounced, and when the Auto tune mode is turned on. the brightness of the screen, the dependence of brightness on the brightness of the image becomes even stronger. For example, let us compare the dependence of brightness (vertical axis) on time (horizontal axis) when switching between shades of 25% and 75% (by the numerical value of the color) with off (green graph) and on (red graph). screen brightness:

It can be seen that the brightness of the dark shade (25% or (64, 64, 64) in 8-bit RGB representation) practically does not change, while the brightness of the light shade decreases noticeably when this mode is enabled. As a result, the dependences of brightness on the hue obtained by us (gamma curves) may not correspond to the gamma curves of a static image, since the measurements were carried out with sequential display of shades of gray on the whole screen.

The color gamut in the case of the Dynamic and Standard profiles is very wide:

When choosing the Professional photography profile (for the uninitiated, it sounds more solid than Adobe RGB in the case of the Samsung Galaxy S4), the coverage is slightly tightened (here the black line is the coverage of the Adobe RGB space, the white line is the measured coverage):

Selecting the Movie profile shrinks the coverage even more, but still remains wider than sRGB:

Without correction, the spectra of the components are very well separated:

In the case of the Movie profile with maximum correction, the color components are already slightly mixed with each other:

Note that on screens with a wide gamut, the colors of conventional images optimized for sRGB devices appear unnaturally saturated. However, a visual assessment showed that when choosing a Movie profile, saturation is noticeably reduced, and colors become close to natural. Without correction, in the Dynamic and Standard profiles, the colors are unnatural. for example, the faces of white-skinned people have a pronounced carrot tint.

The grayscale balance is imperfect, but generally acceptable. The color temperature in the Dynamic and Standard profiles is significantly higher than 6500 K, in the other two it is closer to 6500 K, while this parameter does not change very much in the area of ​​the gray scale from white to dark gray. (The dark areas of the gray scale can be ignored, since the color balance there is not very important, and the error in measuring the color characteristics at low brightness is large.) The deviation from Spectra of an absolutely black body (delta E), despite the whistle of values, remains below 10 units, which is considered a good indicator for a consumer device:

All in all, we have a screen that is best in its class, and there are no complaints about its quality.

We liked the sound of both Samsung Galaxy S4 mini speakers. Surprisingly, such a baby turned out to be equipped with very high-quality speakers, which produce loud, clear and even sound in the entire range. however, high frequencies still prevail. However, what is there to be surprised at: after all, the dimensions of this “mini” are practically similar to the dimensions of a “normal” iPhone, while everything is fine with the sound. “Baby” now has to be called a device that is quite normal in size only in comparison with the now fashionable “shovels”. we hope our readers will forgive us.

As for the auditory speaker, the timbre and intonation in the voice of a familiar interlocutor is quite recognizable, the sound is pleasant to the ear and saturated with the entire spectrum of frequencies. Simply put, it is comfortable to conduct phone conversations using the Samsung Galaxy S4 mini smartphone, and nothing causes irritation.

All sound effects when playing tunes with a standard player are united by a technology called SoundAlive. however, some of them, such as the expansion of the virtual stereo base, are available only with connected headphones. The same goes for the sound optimization function.

The grille of the external speaker located on the back of the smartphone has one twig curved outward to raise the body above the surface, but the sound is still half muffled when the device lies on the table with the screen facing up.

FM-radio in the standard configuration, unlike the original Galaxy S4, was found in the smartphone, and a dictaphone was also found. However, the latter only serves to create voice notes. the phone cannot record the voice from the mowing line by standard means.


Samsung Galaxy S4 mini is equipped, like most modern smartphones, with two digital camera modules. The front camera here has a 1.9-megapixel matrix, shoots by default with a resolution of 1280 × 720. The quality of the resulting photos can be judged by the test shot below.

The main rear camera is equipped with a sensor with a resolution of 8 megapixels, like the Galaxy Mega. By default, the camera shoots in widescreen mode, and the maximum resolution that can be set is 6 megapixels with an aspect ratio of 16: 9, then photos are obtained with a size of 3264 × 1836. Such pictures will be received by users of Samsung Galaxy S4 mini with the settings out of the box. Below are some test shots taken in various conditions with factory settings.

Despite its 8MP, the camera is pretty sharp. She copes well enough with noise. The camera performs software processing very moderately and competently, although sometimes you can see its traces. Judging by the test shots taken (although they may not be enough), perhaps there is almost nothing to complain about. The only unpleasant moment was the shooting of the test bench in the dark. Here, of course, the manufacturers are faced with the question of how best to spoil the picture in such a situation: with noise or severe underexposure. Probably, the latter is still better, but, as can be seen from the test shot, in almost complete darkness the camera cannot even really focus. It looks like the camera has a software limitation of ISO 1000, and I think this makes some sense. Although such restrictions are not always needed at all.

Overall, the camera is pretty good. Sharpness combined with reasonable software processing gives a very decent result for 8 megapixels.

The camera can shoot video, by default it does it in the maximum resolution for it. 1080p. Below you can find a couple of test videos taken stationary and in motion. Clips are saved in an MP4 container (video. AVC High@L4.0, sound. AAC LC, 128 Kbps, 48 ​​kHz, 2 channels).

  • Movie (31.7 MB, 1920 × 1080)
  • Movie (44.5 MB, 1920 × 1080)

The set of settings for controlling the camera is standard for modern Samsung smartphones. There are a lot of them, they are all divided into three columns: for photography, for video filming and general. The icons are drawn clearly and large, they are quite distinguishable in the bright sun. Various options for preset values ​​in the settings are combined into ready-made shooting modes that should be used in a given situation.

In the general settings, you can control the volume button during shooting: it can work out zooming, shutter release of the camera or video control. That is, if you wish, you can control the shooting without touching the screen, if you set all the necessary settings in advance and use the hardware volume button. It is also worth noting the possibility of taking a photo while recording a video.

How it was before?

And more recently, the line of Samsung smartphones looked, although very similar to today’s structure, but, nevertheless, was somewhat different from it. It is no longer a secret that the once popular “J” line is ending its existence, and its segment will be covered by the new “A” series, which, in addition to the business class, will also combine the budget segment. But today interesting Galaxy J smartphones are still available with a liberal price tag, but at the same time quite interesting parameters.

Many Galaxy J smartphones remind us very much of smartphones as they were a few years ago. For example, the Galaxy J3 2016 or Galaxy J2 2018 do not have bezel-less screens, and their design still provides a physical Home button instead of a touchscreen on the display. Such an Old School in the world of smartphones. But it is worth remembering that according to Samsung, this line will be gone very soon.

We understand the lines of Samsung smartphones

Smartphones from the famous Korean company Samsung are rightfully considered one of the most popular and demanded. They have a number of proprietary technologies and innovations that can distinguish them favorably from many other competitors. It is thanks to all sorts of features of Samsung smartphones that they become so coveted and beckon a potential buyer. Some may love the bright and colorful display, while others will love the high performance and incredible camera.

But even if we firmly decided that our heart belongs to the Samsung Galaxy, finding the right model can be a daunting undertaking. The thing is that the lineup of Galaxy smartphones is very extensive and it can be difficult to choose only one model from the entire line. To choose the right smartphone model for yourself, you need to understand all the lines that are available today. What are we actually going to do today.

Note ruler. flagship with interactive S Pen

It should be understood that the “S” line is a real treasure trove of flagships. But don’t forget that the Galaxy S is not the only flagship made by Samsung. Another one is the Note line smartphones. But why does Samsung have two lines of flagships at once? It’s very simple, the first, namely the “S” line, is designed for the general public. Well, in fact, even if you have never heard of this line, you still know about the existence of the Galaxy flagship, and what it looks like.

The second line of the flagship “Note” is designed more for business people who use their smartphone not only for leisure and communication, but also for business and work. Today this line is represented by the Samsung Galaxy Note 9, but in the fall of this year (or maybe a little earlier) we expect the presentation and release of the anniversary ten. A distinctive feature of the Galaxy Note 9 (in fact, like its predecessors) is a kind of stylus, which Samsung proudly calls the S Pen.

Starting with the Galaxy Note 9 smartphone, the S Pen has become interactive and with its help you can not only record something, but also control the player or take photos with the gadget’s camera.

The “S” line is the most legendary and most innovative

Smartphones of the “S” line are a kind of visiting card of all lines and all Samsung smartphones in aggregate. These are the real flagships, whose presentation and release are expected throughout the year. So recently we got the opportunity to get acquainted with the Galaxy S10 and S10, but now we are extremely curious about what will happen next year and what the Galaxy S11 will be like.

The “S” line contains all the most modern and technological innovations that are available at this time. These are the most “long-playing” smartphones, but not in terms of autonomy (although often this is also), but in terms of use. Having bought a Galaxy S once, the need to purchase a new smartphone will not be in front of you soon, unlike budget devices, which you really want to replace in a year or two.

And the “S” line is also a kind of testing ground for testing the freshest and most progressive developments. Having demonstrated its developments for the first time on the flagship, Samsung (in fact, like their competitors) is trying to introduce new technologies in other lines, up to the most budgetary ones. A striking example of this process is the bezel-less display technology, which was first demonstrated on the Galaxy S8 and S8 in 2017, but today, bezel-less displays are everywhere and are used not only in Samsung smartphones, but also in others.

To date, the “S” line is represented by three generations at once. Galaxy S8 and S8 in 2017, Galaxy S9 and S9 in 2018 and Galaxy S10e, S10 and S10 in 2019. But there is a feeling that very soon it will remain in the history of S8 and S8. It is also worth noting that the “S” line sometimes left behind the necessary dust and moisture protection according to the IP68 standard, which was previously present in the “A” line, but for some reason it is no longer in modern Galaxy A smartphones.

Line “M”. the most mysterious

This is an unusual, but at the same time, a new line in our country. Exactly! It is new only in our country, but it has already proven itself well in the rest of the world. Now this series in Ukraine is officially represented only by the Galaxy M20 smartphone, which appeared at the beginning of 2019. Its appearance in Ukraine was rather controversial, at some stage the Galaxy M20 was not expected to be seen here at all, but in the end it is still here.

A special feature of the Galaxy M20 was its battery capacity, which reached 5,000 mAh. This is the most autonomous smartphone among all the other lines that we managed to disassemble today. In addition, the smartphone has at its disposal 4 GB of RAM and 64 GB of internal memory, a fast 8-core processor and a large 6.3-inch display. An excellent solution in its value, I really want to count on the fact that the “M” line will receive its continuation and development in the very near future.

What’s new in 2019?

Until 2019, the “A” line was considered a kind of business class for Samsung smartphones. But now everything has changed. It is no secret that the low-end Samsung Galaxy J series will no longer be produced, and the “A” line will cover not only business-class smartphones, but also budget models. A feature of the new Galaxy A smartphones has become an attractive appearance, frameless Infinity Display screens, high-capacity batteries, as well as increased built-in memory. And in fact, remember when a Samsung smartphone at an average cost of UAH 7,499 offered us 64 GB, as does the Galaxy A30.

The new models do not have the usual protection against dust and moisture in the new models, as there will be no metal case either. The new Galaxy A is made of plastic, although it looks very much like real glass. Among other things, the updated “A” line supports the trend towards larger screens. The smallest model, the Galaxy A40, has a 5.9-inch display, while the Galaxy A70 and A80 measure up to 6.7ʺ.

What she used to be?

Despite Samsung’s active launch of new models in the Galaxy A lineup, we still have 2018 models available. It is they who are closest to the origins that made the line so famous. Some time ago, Galaxy A smartphones had a metal case, which delighted users who were accustomed to inexpensive plastic gadgets. Now you can feel a smartphone made of aluminum in your hand thanks to the Galaxy A6 and A6 2018.

Samsung’s attempt to combine durable metal with elegant glass was also justified, which is perfectly implemented in the Galaxy A7 and A9. These models became the first smartphones with three or even four main cameras not only in their line, but in general. Of course, even last year’s models deserve attention and have sufficient potential. But it should not be news to anyone that Samsung in the “A” line will do Accent precisely on the new model line.

How the Samsung Galaxy S10 differs from the Galaxy S10 and S10e

Since March 1, new Samsung flagships are already on sale in Russia: a regular Galaxy S10, an enlarged S10, as well as a relatively inexpensive S10e.

On the one hand, all devices in the new line are very similar. On the other hand, they differ in price and feature set. We decided to find out which one is right for you.

Cameras: 3, 4 and 5 cameras for S10e, S10 and s10 respectively

Single camera cutout is virtually unobtrusive

The Galaxy S10 and S10e have the same front-facing cameras. Each received a single module with a resolution of 10 MP, autofocus, shooting in 4K and an aperture of f / 1.9.

For them, there is a small round cutout in the upper right corner of each of these smartphones.

In addition to this module, the Galaxy S10 received a special 8MP portrait lens. It measures the depth of space to take pictures with background blur.

This smartphone in the upper right corner is not a round, but an oval cutout, in which two holes fit.

It’s good that the company managed to preserve the touch layer above the cameras, so devices respond to gestures on it.

A whole set of main cameras

Galaxy S10 and S10 have three main cameras.

First 12MP f / 1.5-2.4 variable aperture module, wide-angle with 77-degree field of view.

Second 16 MP module with f / 2.2 aperture, it is ultra wide-angle with 123-degree field of view.

The third 12 MP module is a telephoto lens, which is needed to simulate optical zoom and create portrait shots.

Galaxy S10e does not have a telephoto camera, the other cameras are no different.

Conclusion: the S10e does not have a telephoto lens for optical zoom and portraits, but the S10 has an additional front camera for blurring the background in selfies.

Design: Galaxy S10e can be found in a bright yellow casing

The colors of the new Samsung flagships for every taste

The Galaxy S10 and S10 come in three primary colors: Mother of Pearl (white), Onyx (black), and Aquamarine (green). Premium versions of the latter are also available in white and black ceramics.

In addition to the three base colors, the Galaxy S10e received a Citrus yellow body.

Galaxy S10e: 142.2 x 69.9 x 7.9mm and 150 grams.

Galaxy S10: 149.9 x 70.4 x 7.8mm and 157 grams.

Galaxy S10: 157.6 x 74.1 x 7.8mm and 175g.

The ceramic version of the S10 weighs 198 grams.

In addition to the main connector on the case of each of the devices, you can find a 3.5-audio output, which many have long considered obsolete.

All devices are protected from moisture according to the IP68 standard. But the protection against scratches is different: the S10e uses less technological Gorilla Glass 5 instead of Gorilla Glass 6 in older models.

Conclusion: with the release of the new Galaxy line, Samsung has successfully occupied three niches: compact, standard for 2019 and large flagships.

Screens: Galaxy S10 and S10 differ only in size

Screens for every taste

In the Galaxy S10, Galaxy S10, and S10e, Samsung uses Super AMOLED displays. They support the Always-on display function, which makes it possible to show important information on the screen even in an inactive state.

The screens of the new flagships have a marketing name, Dynamic AMOLED.

The company says these are the most innovative displays ever to be found in a mobile device. No wonder, because she makes them herself.

Prior to the Galaxy S10 line, the company was against any cutouts in flagship screens. This set it apart from its competitors. But now each device has a hole for the front camera, which is cut with a laser.

The screens of the Galaxy S10, Galaxy S10 and S10e are called frameless. At the same time, an asymmetrically large lower frame or “chin” immediately catches the eye. Too bad even Samsung couldn’t handle it.

Galaxy S10 with 6.4-inch screen

Galaxy S10, Galaxy S10 and S10e screens differ in size and resolution.

samsung, differs

The S10 has a 6.1-inch screen with a resolution of 2960×1440 pixels and a density of 550 PPI curved on both sides.

The S10 has a 6.4-inch double-curved screen with a resolution of 2960×1440 pixels and a density of 522 PPI.

The S10e has a 5.8-inch flat screen with a resolution of 2280×1080 pixels and a density of 438 PPI.

The latter also has wider bezels that put it in place of the iPhone XR next to the iPhone XS.

Conclusion: S10 and S10 screens differ only in size, s10e has wider bezels and lower resolution.

Performance: Drives Most Differences

S10e in theory could be the fastest

The hearts of the Samsung Galaxy S10 from the Galaxy S10 and S10e are the same Exynos 9820 or Snapdragon 855 processors, which are used in the United States.

The main models in the lineup received 8 GB of RAM, the only exception was the ceramic version of the S10 with 12 GB of RAM.

Since the S10e has a lower screen resolution, we can conclude that it should work much faster than its older brothers in the line. However, this remains to be verified.

The gadgets are available with different built-in memory options:

Galaxy S10e is available in 128GB or 256GB variants.

Galaxy S10 sold in 128GB and 512GB storage options.

Galaxy S10 can be taken with memory of 128, 512 and 1024 GB.

All devices support microSD memory cards up to 512 GB, so the memory of the top device can be downloaded up to 1.5 TB.

All devices are equipped with USB-C, work with wireless charging and can charge other gadgets that support the Qi standard.

The S10e has a 3100 mAh battery.

The s10 fits 3400 mAh.

S10 4100mAh battery.

Conclusion: oddly enough, in the future, the S10e may turn out to be faster than the s10 and s10 due to the lower screen resolution.

Biometrics: S10e didn’t get an under-screen finger scanner

Fingerprint scanner under the screen

The entire Galaxy S10 lineup can recognize you by sight with the front camera. However, this authentication method can hardly be called secure, and it is not so difficult to deceive it.

To maximize the protection of data on your device, it is best to use a fingerprint scanner.

On the Galaxy S10 and S10, the fingerprint scanner works with ultrasound. It is located at the bottom under the screen and should work even if you use it with dirty hands.

samsung, differs

It’s a shame, but the S10e has a more primitive capacitive sensor. It sits on the side of the smartphone and is virtually identical to the one used on the back of the Galaxy S9.

However, the S10e has an edge in this regard. The fact is that the ultrasonic module almost does not work when using protective glasses, so only a film can be glued to the S10 and S10 screens.

Conclusion: S10 and S10 finger scanner under the screen, S10e on the side.

Bottom line: Choosing a Galaxy smartphone for the price

Which one is better? The one that’s right for you

The current for today are.

Samsung Galaxy S10e: from 56,990 rubles. in the colors Onyx, Aquamarine, Mother of Pearl and Citrus

Samsung Galaxy S10: from 68,990 rubles. in colors Onyx, Aquamarine and Mother of Pearl

Samsung Galaxy S10: from 76,990 rubles. in colors Onyx, Aquamarine and Mother of Pearl

Samsung Galaxy S10 Ceramic: from 124,990 rubles. for the version in a ceramic case in black and white with 1 TB memory and 12 GB RAM.

The devices are different in terms of positioning and cost. The S10e will be chosen by a younger audience, the s10 will be sorted out by business customers, and the s10 will be chosen by geeks who want the most.

Samsung even managed to break into the Luhari segment with a ceramic device.

If you want an Android smartphone from a top brand, go for either one. Each of them is worthy of attention and is suitable for the role of the main smartphone.

How Samsung Galaxy A differs from S

Samsung’s Galaxy series is currently identified with the full line of Android smartphones. The flagship model of this series surpasses the iPhone in sales. We can say that the Galaxy series is now not just the flagship of the smartphone line, but a full range of devices from budget to top-end ones. The price differences between the Galaxy lineup itself are very large. If you are serious about buying a new smartphone, then it is necessary not only to distinguish the series of the manufacturer’s models, but also the series within the Samsung Galaxy line itself.

The Galaxy S smartphone appeared on the market in 2010. The device had a huge display at that time (4 inches, resolution 480×800 pixels), a proprietary ARMv7 processor with a frequency of 1 GHz. The size of the built-in memory is 8 or 16 GB, the camera is 5 megapixels. It is fair to say that until recently, the variety of Samsung smartphone lines was so great that it was very difficult for an ordinary buyer to understand it, and the new items that came out confused the situation even more. Now you can simply answer that the A-series is the middle segment of the Galaxy line, and the S-series is the top segment.

But this is oversimplified. If we compare the devices of these two series more seriously, it turns out that not everything is so simple. Some differences can be a plus, while others turn out to be a minus for a certain model.

Series comparison

Choosing from two series of smartphones in the Galaxy line from Samsung, you can easily understand that in terms of functionality, the S series is a cut above the average of the A series. However, if you compare prices, then the possibility of a significant overpayment for dubious functions can push you away from the purchase.

Types of smartphones from Samsung

Phones with the letters A, S and J belong to the same family called Galaxy. It combines smartphones of different price segments, for different users and their requirements. Smartphones have many differences, after understanding which anyone can choose the right model for themselves.

Technical differences between smartphones

The most important differences are the functional features of smartphones. Each of them is created for separate purposes, so let’s dwell in more detail on the “stuffing” of gadgets from different series.

Differences between the A, S and J lines

The main differences in the lines can be seen in the design of the cameras. For modest representatives of the J line, the parameters of the main camera do not exceed 16 megapixels, starting from the 6th number, the phones have a double camera module, while the front one is represented by modules from 8 to 16 megapixels. Line A has a wider range, the younger the model, the greater the parameters of the lenses. Latest copies have 2 or more lenses to expand camera functions, added wide-angle and / or macro lenses.

samsung, differs

The premium series of smartphones includes all of the brand’s cutting-edge camera developments. The latest copy has 5 lenses, the main module includes a conventional 16.0 MP camera with an F1.5 / F2.4 aperture, optical zoom up to 10x, an ultra-wide 12.0 MP lens and a 12.0 MP camera with increased depth. Front module has a separation capacity of 10.0 MP 8.0 MP.

The S line also has a traditional division into the standard series and the S. The latter are improved variants of the flagship. They did not provide any innovations, but the existing parameters were improved: the amount of built-in memory was increased, the separation capacity of the camera was increased, and the performance was higher.

Samsung Galaxy S

Samsung’s premium line is renowned for the following qualities:

  • implementation of all the latest brand developments in one device;
  • prestige due to a large-scale advertising campaign and high cost;
  • the presence of a large amount of memory;
  • interaction with other Samsung devices, the ability to create a unified system of gadgets;
  • increased protection of personal data, protection of the case from dust and moisture.

The advantages of these smartphones give rise to increased demand among active smartphone users, businessmen, connoisseurs of technological innovations.

Design differences

The first thing the buyer focuses on is the appearance of the smartphone. Most of the models do not have significant design differences, but if this is an important criterion for you, check out the design features of each line.

  • The J series features a metal body and simplicity of shapes and lines. The models of this line are distinguished by their simplicity and recognizable forms. Smartphones are typically 5.5 inches, making the J-series phones ergonomic and compact.
  • The A-series is distinguished by a strict design, a combination of the reliability of a metal cover and a screen protection with tempered glass. Slim, medium size, 4.5 to 5.7 inches diagonal.
  • S-series smartphones are the largest in size. their screen diagonal ranges from 5.5 to almost 7 inches, the display itself occupies almost the entire front panel area. With each update of the lineup, the edges become smaller, and the manufacturer tries to make the edges of the case as smooth as possible in order to improve ergonomic performance. Oleophobic coating used for metal cover and screen.

What do the letters A S J mean in Samsung smartphones

Samsung is trying to reach as many active users as possible, so it releases several lines of smartphones at once. from budget to premium. For the convenience of users, the lines are named with serial numbers with a capital letter of the series. Let’s take a closer look at what the letters A S J mean in Samsung smartphones.

Samsung Galaxy A

Serie A is loved by many for the following features:

  • a large variant of body colors. often smartphones are produced in several shades, where, in addition to standard black and white, various shades are presented, for example, golden, blue, red, etc.
  • focus on the front camera, relatively high performance of front lenses in comparison with competitors;
  • protection of the case from moisture and dust;
  • average price, availability of basic functions and quality of the brand without overpayments.

All these qualities make the devices of this line popular among young people, who like to use smartphones to solve most everyday issues.
