Disabling the proximity sensor service codes. How can I enable or disable the Motion Sensor feature? Removing physical obstacles

Twitter

Why doesn't the screen on my phone go dark when I hold it to my ear? In this article you will find information on how to enable the screen lock function during a call in Xiaomi settings. If on your Xiaomi smartphone when incoming or outgoing call The screen stopped turning off and locking when you put the phone to your ear, then perhaps you turned it off in the Android settings this function. This could happen completely by accident and you simply didn’t notice, or your children went through the phone’s settings and turned off the proximity sensor. In our example, we will show how to enable the proximity sensor on the Xiaomi Redmi 4X so that when you bring the phone to your ear, the screen will lock and go dark. Perhaps the information will also apply to other Android smartphones and tablets.

In order for the screen to automatically lock on Android when you bring it to your ear, you need to do the following actions. We open the phone icon on Xiaomi and get to where we usually dial the number to call. Next, press the “menu” touch button in the form of three horizontal stripes. (On some Androids, after opening the phone, the “menu” can also be opened with a touch button in the form of three stripes located under the screen on the left side. This button must be pressed and held a little to bring up the menu.) Look below at the attached pictures, where the necessary icons are highlighted and buttons.

Next, in the menu window that opens on Xiaomi, select the item Incoming calls, under which there will be short description possible settings (additional settings device behavior for incoming calls).

In the "Incoming calls" settings on Xiaomi, find and select the item Proximity sensor under which it will be written (turn off the screen automatically when you bring the phone to your ear during a conversation) and turn it on. Done, now when you bring the phone to your ear, the screen will turn off and lock, thereby preventing accidental presses and touches on the touch screen.

We will be glad if you add feedback or share useful information.
Thank you for your responsiveness, Additional information and useful tips!!!

Thank you, useful information

Many products modern electronics equipped with sensors that detect the proximity of an object, for example, a finger, to the keyboard or a person’s ear to the phone. This technology is actively used in various types, which allows eliminating mechanical switching of devices, as well as extending their service life. And many may well have a question: a proximity sensor in a phone - what is it and how does it work? Next, this device will be considered from the point of view of implementation using capacitive technology.

Proximity detection

Proximity recognition using non-contact technology quickly found application in the field of portable devices, feeding autonomously. The function is actively used in latest models smartphones and tablets, in music players. Its main purpose is to increase the reliability of devices and save electrical energy.

The display of the device will be inactive until the approach of the user’s hand is detected, which is what the proximity sensor in the phone is responsible for. What this is will become clear if we consider the principle of its operation. When we're talking about about use similar technology, then it is worth noting that in standby mode, energy consumption is exclusively CPU. And when the approach of a palm or finger is detected, the display turns on, displaying current information. All this allows you to reduce the average power consumption of the gadget, while increasing the time battery life batteries.

Features of using the function in different technologies

In home automation, the proximity recognition function has also become very widespread. Non-contact sensors are used to turn on the opening of water supply taps when a human hand is in their field of action; The displays of refrigerators and microwave ovens will be inactive until the user's hand approaches them. New home automation systems are also equipped with this function. used for control household appliances and lighting, are configured to serve as digital photo frames. But as soon as one of the people approaches them, Enough interesting technology is the proximity sensor in the phone. What this is will help you understand the description of the method by which recognition occurs.

Proximity recognition methods

When, for example, a finger approaches the sensor, the total capacity of the system changes. This is what is used to detect an object near a contactless sensor.

Capacitance change detection

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

Successive approximation method

IN in this case The switched capacitive circuit is charged. From this capacitor, voltage is supplied to the comparator through a low-pass filter, where it is compared with the reference voltage. The counter, synchronized with the generator, is locked using the output signal of the comparator. This particular signal 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 transient noise along the supply circuit.

Advantages and disadvantages of recognition technology

Sensor Android approximation, like others, has certain characteristics. The advantages in this case include the following:

Quite a large detection area;

High degree of sensitivity;

Relative affordability in terms of price, because the production of sensors is carried out from fairly cheap components - copper, tin oxide film, indium and printing ink, external wire sensor;

Small size;

Versatility of design;

Temperature stability;

Possibility of functioning with the use of various non-conductive coatings, for example, glasses of different thicknesses;

Durability and high reliability.

Available from this method and certain disadvantages:

The sensing element must be conductive in order for it to detect proximity; however, he may not detect a hand, for example, in a rubber glove;

The capacitive sensing method works in such a way that when there are metal objects in its operating range, the range decreases.

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. Exist special applications, which make it possible to lock the screen by simply swiping your hand over it. To turn it on, you need to press a hardware key.

Calibration

Quite often, users encounter an unpleasant situation when the screen is not locked during a conversation. It also happens that after finishing a call, the display does not turn on, which is why the phone does not unlock. For example, the Nokia proximity sensor does not work correctly. To fix this problem, it needs to be calibrated. Typically, most manufacturers use specialized software for these purposes, which can be downloaded from the official website.

IN latest versions Android 4 calibration function is located directly in the menu. To do this, you need to go into the settings, find the screen, and then select Proximity Sensor Calibration. After covering the sensor with your hand, click OK in the window that appears. Sometimes calibration is allowed without covering the sensor.

You make or answer a call without putting your Android smartphone to your ear and the screen immediately darkens (becomes black) and remains that way.

If this is the case, then the proximity sensor on your xiaomi redmi 4x, sony xperia z3, lenovo, samsung note 3, asus zenfone, meizu, lg, xiaomi... .

Take a look below at what you can do yourself to try to fix the problem before you decide to send your phone in for service.

The proximity sensor has several functions, but its most important task is automatic shutdown screen during a voice call.

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

It's located at the top of the screen and recognizes whether an object (in this case your face) is within a certain distance.

When you put the phone to your ear, the sensor detects your head and the screen goes dark. You then drain the battery less and prevent accidental press.

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

When the proximity sensor does not work properly, the above mechanism stops functioning because the phone cannot somehow detect whether 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 call is completed, or quite the opposite - the screen does not turn off, even when you bring it closer to your face during a call.

The sensor simply “freezes” in one “position” and all the time either detects something nearby or does not do so at all.

Reasons why the proximity sensor does not work on Android

The problem can arise both in the software layer and in a purely mechanical one.

If it is related to software, you can usually fix it yourself, such as by calibrating it, by restoring your phone to factory settings, or by reinstalling the software from scratch.

If the problem occurred as a result of, for example, dropping the phone, it is likely that it was mechanically damaged.

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

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

Of course, it's best to solve it purely mechanical problems by sending the equipment to the service center for servicing.

There they will replace the sensor or the upper part of the housing. However, when it comes to software problems, you can try to solve 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 continue using your phone without repair.

Method one: what to do if the proximity sensor does not work

A common source of problems with the proximity sensor are smartphone accessories that, due to their design, hide it and cause it to erroneously recognize the distance the phone is from another object.

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

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

Yes, well-proven tempered glass will not damage the device, only in local GSM stores you will also find tons of very cheap, questionable quality products that are not suitable for the device.

Uncoupling tempered glass can help restore functionality. Of course, this may seem funny to some, but for Uncle Google, all you have to do is type the word “tempered glass proximity sensor” to find hundreds of posts from users all over the world where they complain about problems after gluing poor quality tempered glass.

Method two: 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 the sensor's functionality.

In this case you can use free application, which after installation can perform recalibration in several steps.

Download the Proximity Sensor Reset app at the end of this post and then run it. Click "Calibrate Sensor" and wait for the wizard to go through the entire calibration process step by step.

The first step is to cover the top of the screen with your hand to cover the proximity sensor and let you know there's an object nearby.

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

You can then check if the calibration helped - if it did, the screen should now dim properly and light up during a call depending on whether the phone is held to your ear.

Method three: what to do if the proximity sensor does not work

The third solution that you can try for yourself is to restore your phone to factory settings.

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. The factory settings option is located in different places depending on the 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 (selecting a language, logging into account Google, etc.). After the operation is completed, check that the screen works correctly during a call.

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

If your phone is no longer under warranty and all other solutions have failed, then you probably have a mechanically damaged proximity sensor and it is stuck in one position, causing the screen to turn off immediately after starting a call.

If you don’t want to spend money on repairs, you can use an indirect solution to the problem - turn off the proximity sensor.

This will keep the screen constantly lit during a call, allowing you to use the on-screen buttons to activate the mode speakerphone or turning on the keyboard.

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

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

Make ROOT.
Install TWRP recovery.
Install Xposed Framework.

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

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 universal methods, which you can use (for the latest Android versions, there are none).

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

Go to the Xposed installer and select the Download tab. Find the module named "Sensor Disabler".

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

Version 1.1.1 is much more stable, while newer ones often lead to random reboots of the device. Good luck.

In this article we will look at the most FAQ related problems proximity sensor.

1. The screen does not turn off when you approach your ear while making a call, does this mean that the proximity sensor is not working? Answer: of course not. The screen is blocked, but does not go out immediately. You can check the operation of the sensor in service menu.2. How to solve the problem with the proximity sensor? Answer: factory calibration does not always work adequately. Created for this purpose special programs for calibration and saving settings after a reboot. The application was created for those who experience difficulties with the proximity sensor. Known problems: - The phone screen does not turn off when approaching the face. - The phone screen turns off when approaching the face but does not turn back on, you need to remove or insert the battery .These problems are often encountered when using custom kernels and firmware. We will configure it using the DHD Proximity SENSOR RECALIBRATOR program.

Instructions:1. Install the application on your device.2. Launch the application on the device.3.Press the button to start monitoring on the device.4. Place your finger on the proximity sensor (small window next to the front speaker and front camera eye).5. Adjust the maximum and minimum values so that you are comfortable. If the screen does not turn off, this most likely means that the factory settings are too high. If the screen does not turn on, this means that the factory settings are set too low. These settings will be applied and saved, they will be applied every time the device is rebooted. There is no need to re-configure each time the device is used. When the settings are applied, the system will notify you that the settings have been applied. Uninstall: If you no longer want to use these settings or programs, simply uninstall the application from your phone. Reboot it. The factory settings will take effect immediately. This application does not change the system and does not require administrator rights (root). There is a possibility that the sensor is simply clogged. It may also be buggy bad contact a train that can come off due to various impacts.

If the DHD refuses to work, and sensor calibration did not bring results, then we can safely say that the sensor cable has come loose and the device needs to be taken to a service center

How to calibrate the G-sensor, screen, light sensor? This method calibration of the sensor and sensor does not require administrator rights (root) or any programs, because all manipulations are carried out in the service menu before the system boots. Let’s look at the points:

1. Loading into FASTBOOT mode, for which, when turning on the device, you need to hold down the camera button until white screen with the inscription FASTBOOT in the upper right corner. IN various devices The key combination for hitting FASTBOOT may be different.2. The keyboard pops up, enter *#301#3. In the pop-up list, select item 08 Sensor and press Enter on the keyboard.4. We place our device on a horizontal, flat surface. The surface must be perfectly flat. The G-sensor is very sensitive. 5. Press RUN, SAVE. We have calibrated the G-sensor, but we need a couple more points. 6. Proxinimity sensor - proximity sensor. To debug it, simply move your hand over the sensor window (located near the front speaker grille and the front camera window). The red inscription will change to green, we calibrate the light sensor (ALS).7. To calibrate ALS, simply shine any flashlight on the sensor. 8. All fields turn green - calibration is complete!9. Click Pass.10. We returned back to the engineering menu, where by typing 00, we will enter FASTBOOT mode. We reboot the device and are glad that all the sensors began to work correctly.

Now let's look at android way How to disable the proximity sensor.

To do this you can use the program Smart Screen Off. This program has good functionality, in addition to calibrating the proximity sensor and the ability to turn it on and off. This software can also turn off the screen when the sensor gets into the dark (put it in a pocket or cover it with a cover). The program has a Russian interface and you can easily understand it. Link to this program search on our website or look at the end of this article.

There is, of course, the most radical way to disable the sensors, but I will present it more for show than for real use. You can completely disable the proximity sensor by removing it and simply disconnecting it from the common board. To do this, we will need a screwdriver with small bits, especially with hexagons, because all the screws in the devices are mostly hexagonal. We will also need growing hands, you know where)

Let's start by filming back cover phone, then take out everything that can be taken out (battery, SIM cards, flash drive, various plugs). Now let's get ready for the most IMPORTANT!!! If you continue, the warranty will be void for you and you will only have to pay to take the phone to the service center. YOU THINK??? Now that you have made up your mind, let’s move on. We unscrew all the screws that are under the cover, and those on the case too, since they will interfere with our ability to remove the case and separate it from the board. Having unscrewed it, we place the phone with the screen on the table, having previously placed it there some kind of cloth to prevent scratches on the glass of the device. We don’t want to leave small scratches while we smack the phone on the table. Now carefully remove rear housing devices. We see the board, we need to unscrew the small screws there too, since the light sensor is attached to the back side of it. Having done this, CAREFULLY lift the board, separating it from the screen (without tearing off or disconnecting anything) Find it on top reverse side the proximity sensor eye and the flat wire (cable) coming from it. Carefully disconnect the end of the cable from the board. Now we put the board back in place and screw it back in place. Then we screw the body. And finally we install all the details (flash drives, SIM cards, dongles) We try to start the phone and make calls on it! I hope this article was useful to you and if so, please leave your comments under this article. Thank you for your attention)

How to disable the proximity sensor on Android

Hello everyone, dear users mobile devices on the base operating system Android and, of course, the readers of this useful resource. In today's material I will tell you how to quickly and easily disable the proximity sensor in mobile gadgets on android.

But, first, let me define the proximity sensor and tell you why it is needed and what functions it actually performs.

A proximity sensor is a device that triggers certain actions when you approach an object. The most obvious example: the call acceptance button is automatically pressed when you bring the Android device to your ear. The proximity sensor can also serve other purposes.

It may seem that the sensor is a very useful thing, but in some cases it only gets in the way. For example, in cheap Chinese devices such a sensor works very poorly. Therefore, it would be better to disable it completely; fortunately, this is very easy to do; you just need to make a small adjustment in the Android operating system.

It is this tincture that we will talk to you about in this material. So, let's go - turn off the proximity sensor.

Shutdown

I will look at disabling the proximity sensor on Android using an example Galaxy phone S4.

On all devices, the principle of disabling the proximity sensor is different; it depends not only on the version of the operating system, but also on its adaptation to specific model smartphone from that other manufacturer. But, by and large, the principle of disabling is the same everywhere, only the names of the items may differ slightly, so keep this in mind.

Follow these steps:

Additional methods

If the method described above does not work for you to disable the proximity sensor, then you can use one of the following, some will probably work for you. So, let's look and apply:

In order to disable the sensor, if no method in the settings helps, you can use special software installed on your Android device. The application is called Smart Screen Off and you can download it from this link. In addition to the proximity sensor, this application will also allow you to configure other functions of your Android device;
Also, it may work on some devices special request to turn off the sensor. The request looks like this: *#*#0588#*#*. Enter this code and press the call button. This method, of course, does not work on all devices, but it may work on your smartphone model.

Android proximity sensor. How to turn it on, turn it off, configure it?

Many users quite often encounter a problem when the smartphone screen does not lock during a call. Or vice versa, the display does not unlock after completion telephone conversation. It's all because of the proximity sensor. Or rather, its configuration is incorrect. In this article we will tell you how to properly configure the Android proximity sensor.

What is an Android proximity sensor?

A proximity sensor is a small element of the device that is activated when the phone and any object are physically close. Thanks to proper operation proximity sensor during a conversation, the smartphone display turns off automatically as soon as the user brings it to the ear.

The Android proximity sensor is very useful and even necessary for at least two reasons, namely:

When the screen is off during a call, you will definitely not accidentally press any button on the touch screen, for example, ear or cheek
The Android proximity sensor allows you to save battery power. If the phone screen was turned on during a conversation, the battery charge would be consumed much faster, and this is extremely inconvenient for people who are used to or are forced to talk on the phone for a long time

The proximity sensor is located at the top of the smartphone. As a rule, it is located next to the front camera lens. On some devices, the sensor is visible to the naked eye, while on others it is not so easy to detect. To locate the proximity sensor, simply remove the device from your ear during a call and place your finger next to the front camera. If the display goes dark, it means you have found the sensor.

How to enable proximity sensor on Android?

Usually, the sensor is turned on by default, but if it is not active for you or you accidentally turned it off, then you can always turn on the Android proximity sensor again.

To do this you need:

Go to the phone settings menu
Go to the "Calls" section
After that "Incoming calls"
Next, find the item “Proximity sensor”
Enable Android proximity sensor by activating the checkbox

How to disable the proximity sensor on Android?

Sometimes the sensor does not work correctly, and for their convenience, some consumers want to turn it off. This can be done very quickly and easily. To disable the proximity sensor on Android, you need to follow all the steps in the above instructions, but do not check the activation box or remove it.

If you have any questions, ask them in the comments below!

How to set up a proximity sensor on Android?

If you have the proximity sensor turned on but not working, you need to calibrate it or, in simple words, configure. The easiest and safest option to solve this problem is to download the free Proximity Sensor Reset app from Play Market.

To set up a proximity sensor on Android using this program you need:

Download and install the application “Proximity Sensor Reset“
After starting the program, click Calibrate Sensor
Close the proximity sensor with your hand and select Next
Remove your hand and select Next again
After that, click Calibrate and Confirm
Give the program access to root rights. In the window that opens, click “Allow”
Wait until the device reboots
Check that the sensor is working properly

If these steps do not solve the problem, and your proximity sensor still does not work, then you may need to calibrate the display. For information on how to properly calibrate the display, read our article - Calibrating the screen and battery on Android. Reflashing the device can also improve the operation of the sensor. You can find out information and select the firmware specifically for your phone in the corresponding section of our website.

In some situations, it happens hardware failure, and for correct operation The proximity sensor needs to be replaced. In this case, we recommend contacting service center for the help of a specialist.

Disabling the proximity sensor on Android

Disabling the proximity sensor on Android is not a task that is needed very often, but sometimes it is simply necessary. Sometimes, due to incorrect settings by the manufacturer or simply a breakdown, the screen does not turn on during a call, even if the cheek is far from it.

There are several solutions to this problem and they are all very different. The strangest and most brutal way to disable the proximity sensor on Android is to stick a piece of reflective material with the shiny side inward. This spoils the exterior of the gadget, which means it is suitable only for notorious geeks.

Some dialers, including branded operator ones, support this function out of the box. Check if you have one:

Open your calling app.
Click on menu additional actions(three buttons) and select Settings.
Find the item “Disable proximity sensor” (or similar) and turn it on, or “Proximity sensor” (“Proximity sensor” or similar) and turn it off.

The third way is to use one of the programs from the Play Store. For example, to disable the proximity sensor, you can install the Proximity Screen Off Lite application and configure it as follows:

Screen On/Off Modes

Check “Cover and hold to turn on Screen”
Timeout: 1 second
Check "Disable Accidental Lock"
Timeout: 4 seconds

Check "Disable in Lanscape"
Check "Lock phone on screen ON"

Configure Sensor

Select sensor: Proximity sensor
Value when sensor covered: 0
Value when sensor un-covered: 1

Then click the “Start service” button. If you don’t like the application, don’t forget to “Uninstall” in the app itself before deleting it. We hope you like at least one of the methods described above.

Often, users of mobile devices are faced with the fact that during a conversation, the screen lock does not work, preventing involuntary pressing of the display. The problem in this case lies in the proximity sensor. There are several reasons why this element of the smartphone does not work correctly. Now we will figure out how to enable/disable the proximity sensor on Android, or configure it if necessary.

In this case, we are talking about a small contactless device that recognizes the approach of any object to the smartphone. As a result of the correct operation of this function, the gadget’s display will turn off automatically when you bring the phone to your ear. This will prevent accidental pressing touch buttons during a conversation (for example, with your ear, finger or cheek).

In addition, the proximity sensor on Android allows you to significantly save battery power, since when the screen is turned on while communicating with another subscriber, the battery power is intensively consumed.

Enable or disable proximity sensor on Android

Typically, the sensor on the device is active by default. If in your case this is not the case, or this function was somehow disabled by accident, then enabling it will not be difficult. This is done as follows: go to “ Settings", find the section " System applications ", select the item " Telephone»:

Then click " Incoming calls"and transfer to active position slider in the line " Proximity sensor"(on some gadgets you will need to check a box):

Depending on the smartphone model, activating the sensor will look slightly different, for example, by immediately opening the dialing field, we call up the call settings menu or with the “ Settings", or by pressing and holding the hardware options button. And after that, as was written above, in “ Incoming calls» turn on the sensor:

If the question is about how to turn off the proximity sensor, then, accordingly, we go the same way and deactivate the function (uncheck it).

How to set up (calibrate) a proximity sensor

This element is located at the top of the smartphone, usually to the left or right of the front camera lens:

On some models of Android devices it can be seen with the naked eye, but on others it is quite difficult to detect. If, during a call, you remove the phone from your ear and then bring it closer to front camera finger, then the display, which goes out after that, will tell you the location of the sensor.

It is quite possible that the reason incorrect operation sensor was simply exposed to dust. In this case, restore normal work functions can be done simply by cleaning the device - turn off the smartphone and blow it with a stream of compressed air. Then you need to reboot your gadget and check whether the sensor’s functionality has been restored.

If this manipulation does not bring the desired result, then you can resort to calibrating the sensor, which is performed in several ways.

Using system capabilities

Open " Settings", select the item " Special abilities " (on some devices " Screen"), find the line " Proximity Sensor Calibration»:

Then, we follow the system prompts step by step, and watch the video more clearly:

Through the engineering menu

By using engineering menu you can check the correct operation of the sensor and, if necessary, calibrate it.

To do this, enter the following set of characters in the dialing field: *#*#3646633#*#* Now open the tab " Hardware Testing"(equipment testing) and press the button “ Sensor", select " Light/Proximity Sensor"(light/proximity sensor):

Select " PS Data Collection» (proximity sensor data collection);
In the next window, select “ Get One Data»;
After the number appears " 0 "Put your palm on the proximity sensor on your smartphone and press " Get One Data»;

If as a result we see the figure 255 , this means our sensor is functioning normally.

For settings:

Select " PS Calibration", then " Calibration" After that, without covering the sensor, click on “Calculate min value”. After the message “ Calculate succeed"We bring a sheet of paper to the sensor at a distance of 2-3 centimeters and click on " Calculate Max value", after which we just have to click " Do Calibration"and reboot your smartphone:

Using third party software
