How to use a memory card in a Samsung phone

SD card as internal storage on Samsung Galaxy

As I said earlier, device manufacturers can control this feature. Samsung has long ago disabled available storage on its Android devices. Reason: the company cannot control the performance of the device with such a modification.

For testing purposes, I inserted an SD card into the Galaxy S8 to see if anything changed in the new interface on Android One. It turns out that no.

In addition, Samsung has created a corresponding web page which confirms that Galaxy tablets and phones do not support Adoptable Storage, as this will “reduce the overall performance” of the device.

However, there are rumors that Samsung will sooner or later introduce this functionality to its devices.

Instructions for Android 9. 10

  • Find the “Device Maintenance” section in the Android settings.
  • Press the Memory button. here is information about internal and external media.
  • Tap on the required SD card.
  • On the next screen, click on the menu button on the top right (three dots), go to the storage settings.
  • Set this storage as default device
  • Format memory card (optional).

Instructions for Android 7. 8

To set the SD card as the main storage device on Android 7. 8, you need to:

  • Insert SD card into phone correctly (optional)
  • Check media compatibility with your smartphone (optional)
  • Go to the “Storage” tab in the settings.
  • Make sure the inserted SD card is used as removable storage.
  • Select the SD card directly by tapping on its name.
  • Tap three dots in the upper right corner of the screen.
  • Go to the sub-item “Settings”.
  • Here you can already set the media as the main storage, having previously formatted the memory card.

These instructions are most relevant for Android 7. 8, however, on later OS versions the differences in the map installation algorithm are insignificant.

Save files from the Internet to a memory card

If you are using a Samsung phone with Android 9,

  • Go to the “Internet” application.
  • Go to the “Settings” section.
  • Tap on “Websites and Downloads”.
  • Specify “Where to save files”.
  • Tap on the item “Memory card”.
  • Settings applied.

Some devices do not have these settings. This is due to the fact that

  • you did not open the Internet application, but a Chrome or other third-party browser.
  • the memory card is not readable or is not provided in this mobile device.

What to do if Adoptable Storage is not available

There are a number of smartphones on which these functions may not be available. For example, owners of devices from LG, as well as users of Samsung Galaxy S7-S9, and Galaxy Note series, may face difficulties when trying to use an SD card as the main storage of information on a smartphone. On these smartphone models, there is also a way to install and format the external memory as internal using the ADB Shell. Be careful, this method is only suitable for experienced users, as it can pose serious problems with your smartphone, since it involves manually configuring the operating system through the command line.

After connecting a smartphone with an SD card, completing the necessary steps for installing the software, debugging via USB and starting the command line using software, to install the external media as internal, enter the following:

copy or write a disk ID that looks like disk: NNN, NN

After completing these steps, the card must be formatted, close the ADB Shell application, and on the smartphone, in the storage settings section, go to the SD card and call the menu by clicking on the three dots at the top of the screen and transfer the data to the media from the smartphone. Without this step, data will continue to be installed to the internal drive. After that, the SD card should start to be perceived by your smartphone as an internal memory device.

There is another way, thanks to which you can change the priorities for installing data on the phone, is the use of Root access rights through applications like Root Essentials, but this method is rather risky and strictly contraindicated if you are the owner of a device on an old version of Android.

Do I need to format the memory card before use?

Please note that the process of linking a card to a smartphone as the main storage is irreversible without data loss, since the device, for security purposes, transfers data to the drive using encryption codes that are unique for a particular device. Thus, you are deprived of the ability to use this SD card with any other smartphones and read data from it as long as it is tied to the smartphone as the main drive.

SD card as internal storage on Android 6

Setting up SD card as internal storage on Android. it’s a simple task. Please note that the SD card will be formatted during the process, so be sure to back up your data by copying it to your PC.

It is possible that the Adoptable Storage function is absent, even if the phone is running Android 6. Perhaps the device manufacturer forcibly disabled this function for security reasons.

However, there are command line methods that can force the device to use the media as internal storage.

Here are the instructions for adapting an SD card as internal:

  • Insert SD card into Android phone and wait for it to be detected.
  • Now open Settings.
  • Scroll down and go to the “Storage” section (or Device Maintenance Memory).
  • Click on the name of your SD card.
  • Click on the three vertical dots in the upper right corner of the screen.
  • Click on Storage Settings.
  • Select the option Format as internal.
    Click on “Erase and Format” if you want to format the SD card as internal storage.
  • If Android detects that your SD card is running slowly, Android will report it. Click OK to continue.
  • You can start migrating your data now or do it later.
  • Click Finish to complete the storage adaptation for your SD card.

How to insert a memory card into a Samsung phone?

Most smartphones from Samsung support memory cards, which can, for example, save photos taken with the device’s camera. In this article, we will show you how to insert a memory card into a smartphone if you do not know what to do to do this. By the way, if you want to connect a USB flash drive via OTG, we have already talked about this earlier.

How to Use a MicroSD Card on the Samsung Galaxy S7

You will need a paperclip. You can find it in the kit from a smartphone. If you don’t have a branded paperclip, use a regular paperclip.

Pick up your smartphone and look for the edge on which the tray is located. In our example (Samsung Galaxy S8), the tray is on the top edge.

In the photo above, it is on the right. There is also a small dot on the left, but this is a microphone. do not insert a paperclip into the hole for it!

Insert a paperclip into the hole in the tray and press down.

After pressing, the tray will be pushed in slightly, something like this:

Actually, this is what the tray looks like. Please note that it can take a variety of forms. So, in our example, a tray is used either for two SIM cards, or for one SIM and a memory card. You may have a dual SIM and memory card tray.

Next, insert the memory card. You will not miss the place, since the seat for the memory card is much larger than for nanoSIM, which is used in modern Samsung smartphones. It should look like this:

Insert the tray with the memory card, and be sure to all the way.

If everything is done correctly, you will see a message about the inserted memory card. If the card is already known to the smartphone, information about it can be found in the section “Device maintenance”. “Memory”.

For Samsung smartphones with a removable back cover, the memory card slot is located next to the battery, for example:

You will have to remove the cover beforehand.

If the app is not installed on an SD card

Open the “Applications” item in “Settings”. In the list of applications, select the one that you would like to transfer to the removable card. Click on the app icon and a menu will open. See if it has a “Transfer” option. If there is, click on the option button and select the memory card. This procedure does not require the installation of additional software, you can do it yourself.

Do you want to use your MicroSD card as a real memory expansion and install applications on it? To do this, you need to format it as internal memory. This is easy enough on most phones, but unfortunately some manufacturers such as Sony, LG or Samsung do not have this feature by default. But if your smartphone is equipped with Android Marshmallow or newer, then you can use the command line. However, avoid Android updates after that. How to combine memory correctly, we will tell you in this article.

For phones running Android 6.0 Marshmallow

When the MicroSD card is formatted as internal storage, applications can be completely saved on it. This means that if you download an app with a total size of 2 GB, then there should be 2 GB of space on the SD card. If, however, the MicroSD card is formatted only as a backup, there will not be enough memory, as writes PLATYPUS_DIARRHEA on reddit.

Just because a menu option is invisible doesn’t mean it isn’t working. A few days after posting on Reddit, it became known that the command line can also format the MicroSD card as internal memory in the Galaxy S7. We have successfully tested the instructions with Samsung Galaxy S7, Sony Xperia Z5 and LG G4 running Android 6.0 Marshmallow.

All three smartphones work from the factory or after an update from Android 6.0 Marshmallow and have a microSD card slot. In addition, there is no menu option to format the microSD card as internal storage. Feature only available on HTC One A9 and Motorola on all Moto smartphones.

Why did Samsung, LG and Sony hide this item? I connected each of three smartphones to my computer and each had one microSD card.

Then I entered in the commands described in my blog. Once you open a command prompt window and connect your smartphone, you can enter the first command:

The Command Prompt is now ready to run system commands on your smartphone. In this case, we want to format the SD card or part of it as internal memory. Even if Sony, Samsung and LG deny us this ability in the graphical user interface, we can still execute this command through the console. First, however, we need the ID of the SD card. You can find it out with the following command:

In my case, the disk is called 179.64. Perhaps you have it different. Pay attention to the exact identifier. In the next command, we will format and partition the MicroSD card. Your content will be removed. If there are important files on the card, copy them to another drive or computer. If you want to keep the MicroSD card in your smartphone at all times, you can now partition all your memory. To do this, enter:

  • sm partition disk: 179.64 private

The operation takes a few seconds or minutes, depending on the capacity of the memory card. If you only want to use a certain percentage so that other devices can read it, you must exclude it from your personal section. The 50:50 split command looks like this:

  • sm partition disk: 179.64 mixed 50

This is the end of Paul O’Brien’s leadership, but not the end of the job. If you now want to use re-allocated memory, you must also migrate applications and data. This can be done through the “Storage” section in the Android settings menu. Select your microSD card, then go to the top right side of the menu and press Move Data. You cannot select this menu item before splitting.

Now all downloaded apps will be completely written to the microSD card. Only system apps and updates use internal memory. This means that you will never get an error message due to lack of space.

Introduction to the problem

By the way, one should not think that only the Android operating system suffers from such a problem as a small amount of built-in memory. It is also on “Ayos”. These two systems are in constant competition with each other. Occasionally “Windows Fone” also interferes in single combat, but she soon finds herself thrown out behind the tatami. What is the topic of IOS touched upon? There are facts that invariably prove the “exposure” of this operating system to users. Initially, her code was a mystery. Nevertheless, a similar trend is taking place. But the operating system “Android”, developed by the specialists of the company “Google”, is now becoming more and more closed to potential developers with each update. This is what annoys people who are so used to this operating system.

Clean Master app to move information to SD card.

If the first method is not available to you, use the new method. Repeat step by step the following steps:

All the necessary applications have moved to the memory card and freed up the memory of the smartphone itself. We recommend using the second method, especially if you need to transfer multiple applications. Thus, you can save a lot of time.

Replacement process

In order to start the operation, open the Root Explorer program. We move to the address / system / etc. There you need to find a file called vold.fstab. In it, you should find the lines and parameters that are responsible for the mount points of external and internal memory. They are called, respectively, like this: SDcard and extsd. After that, it will be necessary to swap the parameters. This completes the active phase of the operation. Do not forget to back up your files, and remember that such operations are performed by the user at their own peril and risk.

If your device does not have enough internal storage, you can use the SD card as internal storage for your Android phone. This feature, called Adoptable Storage, allows Android OS to format external storage media as permanent internal storage. The information on the installed SD-card is encrypted and cannot be used in the future on another device.

What is cumulative storage?

Accumulative storage is the main memory of your smartphone, but if necessary, it can be expanded by using an SD card.

This one on Android is called Adoptable Storage. This will allow you to use the removable microSD card installed on your Android phone as your primary storage. Thus, you can easily solve the problem of how to make an SD card the main memory on Android and overcome the lack of space if the phone has a small internal volume.

How to use SD card as internal storage on Android?

How to replace internal phone storage with external SD card on Android? Configuring your SD card to act as internal storage on Android is essentially a fairly straightforward process. There is nothing complicated in this, and you will see for yourself later on.

Please note that your SD card will be formatted during the process. Do not forget to back up your data by temporarily transferring it to the main unit of the phone, desktop computer, laptop or other Smart device.

It is possible that the Adoptable Storage function is not supported by your device, even if the smartphone is running Android 6.0 or higher (it also happens, it all depends on the model and brand of the smartphone). The device manufacturer may have disabled this feature. However, there are command line methods that allow you to force the use of a flash drive for storing data.

Following are the basic steps for formatting.

  • Place the SD card on your Android phone and wait for it to be detected or displayed in the file manager.
  • Now open “Settings”.
  • Scroll down and go to the “Storage” section.
  • Tap the name of your SD card.
  • Tap the three vertical dots in the upper right corner of the screen.
  • Click on “Storage Settings”.
  • Select the format “as internal option”.
  • On the next screen, you have one last chance to decide for yourself if you want to change your mind.

    Do not forget to make a backup copy of the data, after formatting the information will disappear without a trace!

    • Then click “Erase and Format” if you want to format the SD-drive as an internal data storage. You will be notified later if Android detects that your chip is slow. Click “OK” to continue.
    • You can start the data transfer process after completing this procedure or do it at a later stage. The flash drive is ready to be used as an internal unit of the phone.
  • Click Finish to complete the decision making process.
  • Move Photos, Videos & Apps to Your Micro SD Card on the Galaxy S9 | S9

    After completing the formatting process, you can use the removable CD-drive as a “temporary” or “removable” permanent place. But keep in mind that hot swapping and retrieval will now be unavailable, as you may have done in the past. Therefore, do not eject the flash drive without using the Eject parameter.

    In addition, you can practically delete the place accepted by the operating system, which, accordingly, is not recommended, since this can cause certain errors in the operation of the device. Now you know how to make a memory card the main memory on Android.

    Lack of internal memory on a smartphone. step by step instructions on how to use an SD card as internal storage

    If your device does not have enough internal storage, you can use the SD card as internal storage for your Android phone. This feature, called Adoptable Storage, allows Android OS to format external storage media as permanent internal storage. The information on the installed SD-card is encrypted and cannot be used in the future on another device.

    SD Card is a very convenient option for storing photos, songs and videos. Even if you have a lot of internal storage on your Android smartphone, you may always need a large chunk of storage to store long videos captured by your phone’s high definition camera.

    There is one drawback, the LED chip may lag when recording high definition video.

    Android installs apps to its internal storage by default and only occasionally uploads data to the SD card. Thus, you are deprived of installing any additional applications if your phone lacks internal storage, for example, in the case of budget devices on Android One.

    Features of using the map as the main storage

    There are some important things to consider in this procedure.

    When using a storage device, be it an SD-flash drive or a USB-drive, it is important to remember what format this device is in and whether it is supported by the Android operating system, and there are four types of main file formats: FAT32 or exFAT, ext4 or f2fs.

    How to change phone memory to android memory card? The question is not entirely correct, it is impossible to completely replace it, it is only possible to “increase” the additional volume.

    Using your SD-card as your primary storage device can be a great solution for music lovers and TV shows on the way to work or on a long trip. But, as often happens, the expansion of memory always depends on the cost of the required device, because they differ both in speed and volume, as well as in the adaptable function of storing information. Here are some of the nuances that can be viewed from different angles. both negatively and positively:

    memory, card, samsung, phone

      SD cards are slow. This is the painful reality of today’s tiny memory chips. Although they can store tons of data, they are slower than phone storage and have a limited number of read-write cycles.

    Using SD cards as permanent storage will require more frequent read / write operations, which will degrade its performance over time, and in the worst case can lead to complete data loss. It will be especially offensive if there are important documents or expensive for memory photos or unique videos.

    Before swapping your phone memory for a memory card, your Android will do a performance test on the SD card to make sure it is fast enough and can meet the parameters for use as main storage.

    Android will warn about the presence of external storage and may even refuse to accept it if the SD scale is very slow.

    Non-returnable integration into the operating system. With the Adoptable Storage feature, the Android operating system encrypts the external SD card used as internal storage, so it binds to a specific device, without the possibility of further use on another smartphone. The key used to encrypt data on the SD card is stored in the main memory of the Android device. Thus, it is impossible to dismantle the received storage on another phone due to its encrypted nature of the data (you can remove the card, but it will not be detected on another phone).

    However, you can remove the external removable storage from your device and put it back into simple flash drive mode. The device will remember the information about the applications that are on this card to restore the settings when the accepted device is connected later. So you can also use another storage device.

    Always make sure that you do not remove the default SD card during the unmounting procedure, otherwise the storage medium may be damaged.

  • Not all programs can be installed. Almost Android can install almost all applications on its internal storage. However, this also depends on the consent of the application developer. He has the right to enable or disable support for the accepted storage in the application by adding the appropriate attributes to the code of the downloaded program.
  • How to make the storage again a regular USB flash drive?

    If you want, you can undo the changes made with the Adoptable Storage function. Follow these steps:

    • Follow the above method until the step “Touch the name”.
    • Click on it.
    • Click the three dots in the upper right corner of the screen.
    • Click “format as internal”.
    • Click “Format”. The process will take no more than a few minutes.

    Now you can use the SD card as a portable storage and mount it on any other Android device.
