To disable the proximity sensor on Android, you need to follow all the points of the above instructions, but do not check the activation box or remove it.

If you have any questions, ask them in the Комментарии и мнения владельцев below.!

Approach recognition methods

There are a number of ways, including inductive, resistive, optical, capacitive, visual and acoustic. Each of them has certain advantages and disadvantages. The choice of this or that technology depends on the cost and ease of working with it. Consider a proximity sensor in a phone. that it is, certain information will help to understand. Most often, capacitive proximity sensors are used. Their principle of operation is quite simple. The sensor with conductors suitable for it is hidden under a special protective layer. Two conductive elements in close proximity to each other have a certain parasitic capacitance that occurs between the conductive ground layer and the contact pad of the sensor itself. Usually its value is 10-300 picafarads.

When a finger approaches the sensor, for example, the total capacity of the system changes. It is this that is used to detect an object near a non-contact sensor.

Lock Screen iPhone 4

The proximity sensor works in such a way that it allows you to turn off the smartphone screen during a call to prevent accidental key presses. There are special applications that allow you to lock the screen by simply swiping your hand over it. To turn it on, you need to press the hardware key.

Successive approximation method

In this case, the switched capacitive circuit is charged. From this capacitor, a voltage is supplied to the comparator through a low-pass filter, where it is compared with a reference voltage. The counter, synchronized with the generator, is locked by the output of the comparator. It is this signal that is processed for a specific sensor status. The successive approximation method requires a negligible number of external components. In this case, the operation of the circuit is not affected by crosstalk on the supply circuit.

Proximity recognition

Proximity recognition using contactless technology quickly found application in the field of portable devices that are self-powered. The function is actively used in the latest models of smartphones and tablets, in music players. Its main purpose is to improve the reliability of devices and save electrical energy.

The display of the device will remain inactive until the proximity of the user’s hand is detected, and this is what the proximity sensor in the phone is responsible for. What is it. it will become clear if we consider the principle of its operation. When it comes to using this technology, it is worth noting that in standby mode, only the central processor deals with energy consumption. And when proximity sensors detect the proximity of the palm or finger, the display turns on, which displays the current information. All this allows you to reduce the average power consumption of the gadget, while increasing the battery life.

Capacity change detection

How accurately and reliably the proximity sensor will work depends entirely on the accuracy of measurements of the changed capacity of the system. For this purpose, a number of methods have been developed, among which the most famous are charge transfer, successive approximation, capacitance interactions and the sigma-delta method. Two of them are most commonly used. Both use a switched capacitive circuit and an external measuring capacitor.

Advantages and disadvantages of recognition technology

Proximity sensor Android, like others, has certain features. The advantages in this case include the following:

This method also has certain disadvantages:

Proximity sensor. what is it for in the phone, where it is located, how to turn it on, configure

Every modern mobile gadget has a whole set of sensors that are responsible for measuring pressure, heart rate, distance traveled, etc. Today’s post will tell you about the proximity sensor in the phone. what is it, why is it needed, how to check the functionality, configure, enable or disable.

Small detail with important functionality

Where is the miniature component on the phone? Mainly in the upper part of the front side, next to other devices that measure the level of lighting, face recognition, and the like.

To determine the exact location, you just need to dial someone’s number and put your index finger in different places. As soon as the screen darkens, it means you have found the desired point.

The main purpose is to respond to the approach of a third-party object to the device. This is necessary to automatically turn off the screen during a telephone conversation. You probably noticed how the display suddenly goes out as soon as you bring it to your ear, and then reactivates after the end of the communication session.

This is made possible by the presence of a receiver-transmitter link, which sends an infrared signal and then receives information for analysis.

  • The battery charge is significantly saved, especially in the devices, the owners of which talk a lot on the phone. Just imagine the situation. you have a brand new smartphone with a diagonal of 6.7 inches (BUT without a sensor). When communicating with a friend / colleague / family member for half an hour, the device may be discharged by 10-20%;
  • The second positive point is the blocking of the sensor, so that your ear or cheek will not press on the on-screen icons, leading to unpredictable consequences. A vivid illustration. Proximity Sensor stopped working on my old Lenovo A730, and constantly when communicating, I interrupted the call or activated the speakerphone, touching the corner of my ear to the screen.

Proximity sensor in a smartphone. how to setup?

In different operating systems and graphical shells, these parameters are most often located in the call settings. For example, if you open the dialing window and click on the menu icon, you can go directly to the options you need:

In the case of Xiaomi (MIUI 10). open the list of system applications, select “Phone”, then go to the item “Incoming calls” and activate the switch:

How to turn it on. figured it out. But what if not working or not functioning properly? Moving on to the next chapter of the review.

Troubleshooting Potential Issues

I found a lot of messages on the forums that after a software update, custom firmware and other similar actions, the proximity sensor began to function incorrectly.

Also, the calibration of the sensor, performed using third-party software, often saves. This application is in the first place on Google Play. It allows you to test and repair a module:

The utility has been partially translated into Russian, but when you click on the large “Fix it” icon, you will see four steps with explanations in plain language. Just follow the instructions and then restart your device. The only drawback is periodically appearing ads, but they can be easily closed.

So we figured it out. proximity sensor in the phone what is this component and how to activate it, configure.

Automatic reboot

Samsung’s new flagships are able to restart themselves, as a rule, they reboot at night and always with the screen off. The process allows you to save a little charge and increase productivity, although Samsung owners who “played” with the function note that the changes are insignificant. Users can make changes to the process schedule by selecting dates and appropriate times:

  • We visit “Settings” and the “Reset” tab.
  • In the menu, tap “Automatically restart Samsung”.
  • A window will open where users can choose at what time it is most convenient to restart the device’s system.

Please note that automatic restart is only initiated if the charge reserve is more than 30%. In addition, the internal memory must not be encrypted, and the SIM card must not be disabled, otherwise the restart will not occur.

What to do if your phone won’t restart?

The above instructions on how to restart Samsung didn’t help? Then we turn to drastic measures. If you are sure that some installed software that malfunctions and causes conflicts in the system was not the culprit for the inability to restart, you can simply remove the cover and remove the battery. After a couple of minutes, insert the battery back and turn on the device, evaluating its work.

If simple manipulation with the battery did not solve the problem, we use the Recovery menu built into Android. By the way, it is better for inexperienced users not to enter here, since a lack of experience can lead to fatal consequences.

  • Turn off the smartphone by pressing the power button and selecting “Shutdown”.
  • At the same time, we hold down the power, screen activation and volume down buttons, holding them until the Samsung logo is displayed. In some lines, the recovery menu is called differently, information about this can be found on special forums.
  • Navigation through the menu items in Recovery is carried out with the volume key, and the selection of a specific item by pressing the screen activation button.
  • If you need to do a full reset, select the item containing the phrase “Factory Reset”. At the end of the process, click “Reboot System Now” and wait for the device to reboot.

How to restart Samsung if sensor doesn’t work

Reboot with reset

Restarting with a reset will help solve problems with freezing software and buggy applications. This manipulation eliminates program crashes, but does not affect user files at all. After such a restart, the device will start to work stably, its performance will increase, and photos, chat content and important media files will remain intact.

Most often, a Samsung reboot with a reset is required if some software was loaded on the device, which caused significant malfunctions of the device. If removing the program and cleaning with the utility did not bring the desired result, it is advisable to “roll back” the system:

  • Go to “Settings”, stop at “General”, go to “Reset”.
  • We select “Reset settings”, we agree to the manipulation.

Resetting the settings allows you to roll back the smartphone system to the factory level, which work stably and do not conflict with each other. Henceforth, in order to avoid problems that have arisen, try not to get into Android and not install dubious software on an expensive gadget.

How to restart a Samsung smartphone of any model

How to restart a Samsung smartphone. instructions on how to do this may be required by any user whose phone is frozen or has a significant slowdown.

Proximity Sensor

After installing and opening the application, you need to do the following:

  • Rub the sensor with your finger.
  • Attach palm.
  • Slowly move the palm away.
  • Close the sensor with your palm.

At the end of the operation, you need to restart the phone and make a test call. If the operation does not help, you should install an additional application.

Why the screen does not lock during a call

When the proximity component is active, the system automatically turns off the display. When the device is brought to the ear, the display dims, so that the user does not have to worry about accidental taps on the screen. If a technical component is damaged or turned off, the display will not go out.

Screen does not lock when talking Samsung

“Screen does not lock when talking Samsung” is a frequent request on the Internet. The proximity sensor is responsible for blocking the display during a telephone conversation. In most cases, it is disabled by default, so you need to activate it.

The main problems with the proximity sensor

There are several reasons why the automatic blocking feature does not work:

  • The option is disabled. To enable, you need to use the settings parameters and set the correct values.
  • OS updates installed incorrectly. Smartphones are regularly updated, resulting in operation errors on some devices.
  • The technical error. The component can be deactivated due to long-term use of the phone or mechanical damage that occurs when the smartphone is dropped.

If a component is damaged, take the phone to a service center.

ProxLight Override Call Service

The app is called Proximity / Light Restriction-Call Service, which can also be downloaded from the Play Market. After opening the utility, you need to do the following:

  • Click on the center button.
  • The application will go to the settings section.

  • 2 (download if the function is always active)
  • 3 (activates the zoom light function)
  • 4 (changing the parameters of the illumination option).

proximity sensor not working in Samsung | How to fix proximity sensor in Samsung

If none of these methods helped, the problem is mechanical damage to the device.

Where is the proximity sensor

The function is installed only in modern phone models. Older Samsung lines may not have this option. The sensor is located next to the front camera on the display of the device.

How to Set Up Proximity Sensor on Samsung

First, you need to check the operating mode of the device. The operation algorithm may differ slightly depending on the specific shell of the device OS. What to do, the screen does not lock when talking Samsung:

  • Open “Settings”.
  • Go to the “System Applications” section.
  • Select “Call settings”.
  • Click on “Incoming Calls”.
  • Activate the desired function.

If the method does not help, it is recommended to install applications that configure and calibrate the sensor parameters. Downloading utilities is required in the Play Market.

It is not recommended to remove the display yourself and try to fix the phone. This often results in even greater damage to devices. To restore the system, you should contact the specialists at the nearest service center or use the smartphone warranty.

The third way what to do if the proximity sensor does not work

The third solution you can try for yourself is to factory reset your phone.

This option unfortunately deletes all data from the phone, so you must copy files, photos, music, videos, contacts, SMS and others to a safe place.

Then go to settings and select factory reset. Factory settings option is located in different places depending on Android version, phone brand and manufacturer.

After confirming this option, the phone will reboot, and all data will be deleted, and the device settings will be reset to factory settings.

When you start your phone for the first time, you need to go through the setup process again (choose your language, sign in to your Google account, etc.). After completing the operation, make sure the screen is working properly during a call.

Reasons why the proximity sensor does not work on Android

The problem can occur both in the software layer and in the purely mechanical.

If it is software related, it can usually be fixed by yourself, for example, by calibrating, by restoring the phone to factory settings, or by reinstalling the software from scratch.

If the problem is caused by, for example, dropping the phone, it is likely that it was mechanically damaged.

This often also happens when it comes to peeling off the top of the case from the base of the phone (especially on Sony Xperia and Xiaomi redmi devices).

You can see this after the sensor starts working after pressing the top of the screen with your finger.

Of course, it is best to solve purely mechanical problems by sending the equipment for service.

They will replace the sensor or the upper part of the case. However, when it comes to software problems, you can try to fix them yourself.

Let’s see what we can do before we decide to send the device in for repair.

There are several solutions that allow you to keep using your phone without repair.

The second method is what to do if the proximity sensor does not work in Android

Sometimes the source of the problem is a software update that, for some reason, breaks down the sensor’s functionality.

In this case, you can use a free application that, after installation, can re-calibrate in a few steps.

Download the Proximity Sensor Reset app at the end of this post and then launch it. Click “Calibrate Sensor” and wait while the wizard walks through the entire calibration process step by step.

In the first step, cover the top of the screen with your hand to cover the proximity sensor and signal that there is an object nearby.

Click the Next arrow and the next step will appear. In the second step, you need to open the proximity sensor. remove your hand and wait 2 seconds until the sensor catches the farthest object, then click “Next”.

At the very end, you must confirm the new calibration, which will restart the device.

After that, you can check if the calibration helped. if so, the screen should now dim properly and light up during a call depending on whether the phone is held to your ear.

Proximity sensor does not work on Android. there is a solution

You call or answer a call without putting your Android smartphone to your ear and the screen immediately darkens (turns black) and remains so.

How to fix Proximity sensor problems in your mobile ?

If so, then the proximity sensor on your Xiaomi redmi 4x, sony xperia z3, lenovo, Samsung note 3, asus zenfone, meizu, LG, Xiaomi

Check out below what you can do yourself to try and fix the problem before deciding to send your phone for service.

The proximity sensor has several functions, but its most important task is to automatically turn off the screen during a voice call.

This happens when the phone is next to your face. Such detection is possible thanks to him.

It is located at the top of the screen and recognizes if there is an object (in this case your face) at a certain distance.

When you put the phone to your ear, the sensor detects your head and the screen turns off. You then drain the battery less and prevent accidental pressing.

In turn, when you remove the phone from your ear, the screen lights up so that you can disconnect the call or use other functions (numeric keypad, switching the call to the speaker, etc.).

When the proximity sensor does not work properly, the above mechanism stops functioning because the phone cannot in any way detect if it is near your face.

The problem usually manifests itself either in the fact that the screen immediately turns off during a call and lights up only after the connection is completed, or quite the opposite. the screen does not turn off, even when you bring it closer to your face during a call.

It’s just that the sensor “freezes” in one “position” and all the time either detects something nearby, or does not do it at all.

You can also quickly check if the sensor is physically damaged. here are the instructions.

The first method is what to do if the proximity sensor does not work

A common source of problems with the proximity sensor is smartphone accessories, which, due to their design, hide it and cause it to misrecognize the distance at which the phone is from another object.

If you have your device packed in a case, try removing it and see if that resolves the problem. Make a call and check if the screen has turned off after starting a call.

Very often the reason for problems with the proximity sensor is also tempered glass, which is glued to the entire screen.

Unhooking the tempered glass can help restore functionality. Of course, for some it may seem funny, but for Uncle Google, it is enough to enter the word “proximity sensor tempered glass” to find hundreds of entries from users from all over the world, where they complain about problems after gluing poor quality tempered glass.

Method four: what to do if the proximity sensor does not work on Android

If your phone is no longer guaranteed, and all other solutions did not help you, then you probably have a mechanically damaged proximity sensor, and it is fixed in one position, forcing the screen to turn off immediately after starting a call.

If you do not want to spend money on repairs, then you can apply an indirect solution to the problem. turn off the proximity sensor.

This will keep the screen on during a call, allowing you to use the on-screen buttons to activate handsfree mode or turn on the keyboard.

The disadvantage of this solution is that when you are talking, you can accidentally press the button, for example, with your cheek.

To disable the proximity sensor, you must install the dedicated Xposed Framework tool. This requires the following:

  • Make ROOT.
  • Install TWRP recovery.
  • Install Xposed Framework.

Root grants administrator rights, TWRP Recovery installs a custom recovery mode, and Xposed Framework allows you to install additional modules to change hardware and software.

READ  System ui not responding on Samsung phone

One of these modules is an application for disabling the proximity sensor.

Getting ROOT and installing TWRP Recovery largely depends on the device model. However, there are generic methods that you can use (for the latest versions of Android, there are none).

Once you have ROOT and TWRP you can go to install Xposed which will disable the proximity sensor.

Go to the Xposed installer and select the Download tab. Find a module named “Sensor Disabler”.

After finding the module, select it and go to the versions tab. Load the module in version 1.1.1 by selecting it in the list using the “Load” button.

Version 1.1.1 is much more stable, while newer ones often lead to random device reboots. Success.

What to do if the proximity sensor stops working?

You can try to solve software problems yourself by following the steps below.

What to do with mechanical damage?

If the previous steps did not work, it is likely that the sensor is mechanically damaged. Damage leads to the fact that it is fixed in one position and turns off the screen immediately after the start of the conversation. If repairs (often expensive) are not included in the plans of the owner of the smartphone, you can simply disable the module. In this case, the screen will always light up, regardless of the approach or distance of the object. The disadvantage of this method is accidental button presses during a call.

  • sequentially go to “Call log”. “Settings”;
  • select the item “Incoming”, deactivate the sensor.

Factory Reset (Hard Reset)

Important: the procedure for rolling back to factory settings will result in the loss of all data from the phone memory. All data, images, videos and other files must be saved before starting the procedure.

  • go to the “Settings” section of the gadget;
  • select an item that allows you to roll back the system to its original state;
  • a process will be launched, at the end of which the phone will reboot. All data and settings of the gadget will be lost. The first launch of the device will require the user to go through all the settings again (select the language, enter the data of the Google account, etc.).

A cover or protective glass covers the sensor

The reason that lies on the surface is that smartphone accessories interfere with the work, which cover the part and prevent the correct recognition of the distance between the phone and a physical object. It is necessary to check whether the decorative protective cover does not cover the “peephole” of the module. To do this, remove all accessories and check the working status of the proximity function. In addition to the case, the problem can also be caused by tempered glass that protects the phone screen.

High-quality accessories, selected strictly according to the smartphone model, will not cause such interference in work. Cheap counterparts are exactly the cause of breakdowns.

Software problems

The most common reason why Samsung proximity sensor does not work is software update. Installing updates may cause the sensor to work incorrectly or disable it. Re-calibration will be required. For its implementation, a free program is used. Proximity Sensor Reset. Algorithm:

  • download the application and launch it on a mobile device;
  • in the body of the utility, select the “Calibrate sensor” option, wait until the end of the process. At the first stage, you will need to cover the peephole of the module with your hand or finger in order to simulate the approach of a physical object;
  • tap on the arrow to continue the process. At the second stage, remove the hand, wait 2 seconds (at this time, the sensor will catch the object farthest from it), tap “Next”;
  • confirm the performed settings and restart the device. Reboot will happen automatically.

After completing the setup procedure and restarting the operating system of the device, it is necessary to check the functionality of the module. it should light up and go out depending on the approach or distance from the object.

Samsung proximity sensor not working. what to do?

Often during a conversation, owners of Samsung smartphones notice an inadequate response of the screen. it continues to be active when approaching the face, unwanted functions are activated, and when it is removed, the screen remains black during a voice call. This situation occurs when the Samsung proximity sensor does not work. This dysfunction can cause many inconveniences. Conclusion: the device needs repair. Let’s find out: what you can do on your own to calibrate the sensor and bring the phone into working condition.

Using third-party software

There are times when such manipulations do not give any effect and the proximity sensor still works as before. There is no need to be upset, as on the Internet you will find several applications that allow you to disable this sensor bypassing the standard Android settings.

One such application is Smart Screen Off. It provides ample opportunity to customize various sensors and phone buttons. The functionality of this program also includes disabling the proximity sensor. In the program interface, you need to find the appropriate item, respectively, turn off the proximity sensor.

After that, when you call and bring the device to the auricle, the sensor will not work, that is, it will not perform any action. You can download the application on Google Play, and then:

  • Enter the title in the search bar;
  • Go to the program page;
  • Click “install”.

Using the default settings

A simple and extremely affordable way to disable the proximity sensor on Android is to use the standard settings. In each model, this function can be located in different places. However, the general “formula” for disabling a sensor consists of the following steps:

  • Go to the “Settings” section of your Android smartphone.
  • Select the sub-item “Calls”;
  • Find the item “Proximity sensor”, and then uncheck it.

Disabling the Proximity Sensor on Androide

The Android operating system contains many useful features, but some of them may not be needed, in particular the proximity sensor. This is a special sensor that is installed on the front side of the device, and when an approaching object is detected, it performs some action, in particular:

  • Turn off the backlight of the phone when bringing the smartphone to your ear;
  • Automatic call reception when the motion sensor is triggered;
  • Automatically increase the volume when the phone is in your

In some cases, it does not work correctly, so users prefer to turn it off for the convenience of using a mobile phone. There are several ways to disable the sensor: using standard settings, third-party software and using the engineering menu.

Engineering menu and service codes. the solution to any problems

Most modern mobile operating systems, as well as Android, have a so-called engineering menu. It is an advanced smartphone settings that can be used to configure almost any component of the phone, including the proximity sensor if it is not working properly. Before using this menu, be sure to read all the information you can find for your model. The engineering menu is only used by developers or advanced users. Setting the wrong settings can lead to extremely unfavorable consequences. To enter the engineering menu, you must:

  • Enable dialing on your phone.
  • On the keyboard, enter the following combination of characters. ### (depending on the manufacturer, there may be other combinations).
  • If after that the engineering menu does not appear, press the call button.

There is an easier way. enter the service tag. This is a special combination of symbols and numbers, thanks to which you can perform a specific action. If the sensor does not work correctly, you should find a code for your specific phone model by which the shutdown will be performed. Be sure to check out several sources of information on the network, as there are engineering codes that perform a complete reset of all settings.

Other solutions to the problem

Incorrect operation of the sensor can be associated with errors in the Android OS. Try to upgrade and then upgrade to the new version. To do this, follow these steps:

  • Go to phone settings.
  • Select “About phone”.
  • Click on “System Update”.

If your phone’s hardware won’t allow you to upgrade to a more recent OS version, try performing a factory reset. This is done using a special service code, which you can find on the Internet.

Sewn tape can also cause the problem. The ingress of dirt or dust specifically to the location of the proximity sensor will lead to its malfunctions, respectively, and improper operation.
