Why the phone screen is turned off during a call. Why on android goes out the screen during call

Phones from year to year evolve, becoming an increasingly complex device that has on board with a dozen all sorts of sensors. Each of them is responsible for certain functions. For example, for regulating the autowarity of the screen and its shutdown, the approximation sensor corresponds to the conversation, it is also called the light or illumination sensor. Calibration of the approximation sensor on xiaomi Redmi. Or NOTE devices will help to correct the improper operation of the sensor, which can deliver a lot of problems to the smartphone owner, for example, random clicks on the screen during a conversation. The causes of improper work may be several. If you do not help a banal restart of the device, then let's look at the reasons for the degree of their complexity.

Turn on the light sensor

Your sensor can be simply turned off. To turn it on, you need to do several steps, consider on example Xiaomi. REDMI 3S.
Open the application "Phone" (a dialer in common)
Long press on the menu
In the list that opens, select "Incoming Calls"
Then we find in the list "Sensor of the approximation" and turn it on if it is disabled

Part of Xiaomi models of such an option may not be or this function will be distinguished by the location in the menu. Unfortunately, it is impossible to give the universal path of the menu due to a wide variety of models and firmware.

Turn off "harmful" functions

The most common cause of an incorrectly operating sensor is the included "blocking in pocket" function, the meaning of which does not allow the screen when the smartphone lies in your pocket. Due to this option, the light sensor often triggers incorrectly.

This problem is relevant at all xiaomi firmwareFor some reason, the engineers do not want to correct this problem or believe that everything works as it should, however, in some users, this function does not cause problems. To turn off the lock in your pocket, you need to go to the settings, then in "Calls" and then in Inbound Calls, there you can find the slider that turns this function.

What can interfere with the sensor

One of the reasons for an incorrectly operating approximation sensor is physical interference in its work, namely a protective film or glass. For example, our employee at Xiaomi Redmi Note 3 Pro does not work this sensor approximation for this reason. If you do not have holes for the light sensor, then you need to or change the film / glass or do it hole yourself. This sensor is usually located above the screen, next to frontal chamber and a conversational speaker. This problem usually sin low-quality or universal films. Therefore, before buying a protective coating, be sure to check the presence of all holes.

Test and calibrate light sensor

Checking the light sensor

A rather popular solution is to calibrate the approximation sensor xiaomi devices. To begin with, you need to check the sensor performance in the phone, for this you type the following numbers * # * # 6484 # * # * (call button is not needed), thanks to this combination you will fall into engineering menu, Tested on Xiaomi Mi4 and Xiaomi Redmi 3 Pro, other ways to get there are described in our article about the engineering menu.
5 buttons on a black background will be displayed.

Click on the top right, there must be written "Single Item Test".

In the list of components, you need to find and select "Proximity Sensor", it is usually almost at the very bottom.

In the dough itself, the inscription "far" or "close" will be displayed, closing and opening the illumination sensor (for example, with a finger), the inscription must change. If this does not happen, then this module faulty.
After this text, you can try to make calibration.

Calibration of the light sensor

Consider calibration on the example smartphone Xiaomi. REDMI 3S.

Turn off completely smartphone.

Click the VOLUME + button (increasing the volume), and not releasing it, press the inclusion button. Your device must jar, after that, the buttons can be released.

You will open a menu, in 95% of cases it will be in Chinese (including Xiaomi Redmi 3S). You need to click on the "中文" button, it is in the bottom line to the right of the "Download 模式" button. After that, the menu language will be changed into English.

Click on the "PCBA TEST" button in top string And we have an engineering menu.

If the touchscreen does not work, we move using the "UP" and "DOWN" buttons to the Proximity Sensor item and go to it.

It is necessary to horizontally put the phone on a flat surface.

The light sensor should not be closed (it is better to rub it with a cloth).

Make sure that the phone does not fall bright light.

Click on the calibration button "Calibration", the sensor will be calibrated.

After the inscription "SUCCESSFULLY" appears, it means that the calibration has been successfully completed.

Now it is necessary to check the operation of this module, cover the light sensor with an opaque item, on the screen 1 should be changed by 0 and vice versa.

After that, you may need to press the "Pass" button, you will fall back to the engineering menu, click "Finish" there, then "Power Off", the phone must be turned off.

Turn on the phone and check the sensor operation. When calling the screen should go out only when you bring the phone to the ear.
On our personal experience The correct operation of the Xiaomi Redmi 3 approximation sensor was completely restored in this way.

Incorrect device firmware

If the calibration does not help, the reason for the incorrect work of the smartphone may be incorrect flashing, this applies not only to the light sensor. The problem is that new firmware incorrectly rises on a smartphone, getting the remaining garbage from old firmware. This problem concerns the update method through a regular recovery (loader). The transition to new versions should be done through FastBoot or with a reset of all settings and user data (full wipe). Of minuses this method It is worth noting that all your data and applications will be deleted, but all the garbage will be removed with them.

Other reasons

If the previous methods did not have a proper effect, then the reason for the screen can be replaced on poor quality. Unfortunately, on-screen modules for phones xiaomi. Delivered with light sensor. If you have already done the screen replacement in the service, then it is possible that despite all the convictions of the master, you just put a poor-quality screen with a bad sensor. In case, from the beginning of the purchase itself, your smartphone works incorrectly, then a simple marriage can be the reason. We advise you to contact the seller for further instructions.

We hope you helped these advice, be sure to write in the comments if this article helped you and which board helped you.

The approximation sensor in the smartphone, including the iPhone, performs such a function as the screen repayment during the conversation. The function is activated at that moment when contacting something opaque. When a person makes a call or responds to him, this is something else. Today we will talk about why the screen does not go out when talking on the phone and what can be taken in this case independently, without the help of a specialist, including how to check the approximation sensor.

Most often, the sensor of approximation in the smartphone loses its functionality after replacing the touchscreen. In order to solve this problem, just glue a small piece of scotch into this place and paint the dark marker, best of all. This method was tested many times and was always effective.

Instead of scotch, you can use a stationery gum. Cut the piece with a length of about 5 mm and place it between the light and distance mechanisms. This method, according to specialists and ordinary people, also helps to solve the problem when it does not work as it is necessary to disable the display on the iPhone, when approaching in a non-transparent object.

Of course, in order for the distance sensor to be available for repair, the device will have to disassemble, at least remove the display module. Instructions on how to do it owners of iphone. different models, on the Internet is full. To begin with, get acquainted to not block firewood and do not spoil the valuable spare part. The screens are very fragile and with improper removal turn into a pile of glass fragments.

As a rule, the sensor of the distance after replacing the display does not work if the procedure was carried out in people who are not familiar with all the subtleties of opening and repair iPhone. 5 and other products from Apple. Therefore, to replace the display on an iPhone, it is best to turn to real professionals of your business, specialists in which you are 100% sure, preferably in the official service center.

In addition, only there will be a guarantee for work and spare parts for a few months, unlike private servicemen who limit warranty obligations 2-3 weeks.

Transparent protective film or glass

In addition to replacing the touchscreen, the situation when the iPhone approximation sensor does not work, can be caused by a protective film or glass. If we talk more precisely, then its dark tint. Due to the shadension, the distance sensor, despite the fact that it is fully functional, it will not work. Solving this problem - to remove protective film Or glass and replace it to another, transparent, which is quite logical.

There are now a huge number of similar accessories on the market, so there should be no problems with the choice of the right one. The main thing to remember is to take only a transparent protective glass!

It should be noted that if you were put on an iPhone, a protective film or a dark shade glass for a long time ago, there was no such problem, then, most likely, the sensor on the phone has failed for another reason. In this case, it is strongly recommended to contact the master.

Phone recovery

If it is not in replacing the touchscreen and dark protective film or glass, the sensor may not work as a result of failures in the operating system. Therefore, before going to the official service center in order to fix the iPhone 5 or any other apple gadget, we try to reboot. Make it very simple - see the picture and press the marked buttons.

In order to reset all the software errors, you must format the phone. You can do it at iTunes help. How exactly the procedure is made, read and see here in this article.

Fixing loaf

The situation when the screen does not swing, besides all that, as mentioned above, it may be caused by a bucknate spare parts under the name "Clay". It is not much difficult to fix it, but the skill and experience is needed. This process can be divided into the following steps:

Disassemble an iPhone, pull out or turn off the battery.
Pull out the speaker and the connector that serves to fix the headset.
Lay on the part of the key called "Home", repeatedly unscrewing the screws.
If on the details that come into contact with the train, there are traces of corrosion, then carefully clean this place. For this, a cotton wand moistened with alcohol solution.
Install the details back.
Enable iPhone and check the approximation sensor - it works or not.

Remember that the train is very fragile and is literally damaged by one non-accurate movement. Therefore, if you decide to fix it yourself, then do it carefully, without the use of sharp and cutting items.

Remove pollution

The cause of the problem under consideration may be the notorious dust that penetrates the device in disruption of tightness. In order to wipe the phone from the inside, it will be necessary to disassemble the case, and neatly, without pressure, wipe the schemes and the case from visible sera particles.

Disable module

If you are the opposite, like a question: "How to disable an approximation sensor on iPhone," you can use in one of the following ways:

Download smart application Screen Off. The program allows you to calibrate, adjust the moments of turning on and off.
Dial the combination "* # * # 0588 # * # *" \u200b\u200b- program method of shutdown, engineers stitched in depths operating system iOS.
Disassemble the smartphone and remove the proximity sensor - perhaps the most radical way.

Conclusion

Now you know what to do if the screen does not go out when conversation iPhone 5S. Warranty on the iPhone, regardless of the model, is not 1, as many think, and 2 years. Therefore, if this time has not expired, it is best not to engage in self-care, but to seek help in an official service center. There will be a challenge quickly and free. If the module has not failed as a result of drowning or falling the device.

And, finally. You should not buy an iPhone from hand, as in this case, the cellular can be a Chinese product collected from used parts, even with the availability of the documentation confirming. Be careful and careful how to check iPhone authenticityRead in the next article. That's all, to new meetings on the pages of the site!

Video instruction

Does not turn off the screen during the call on the phone? Clicks phone during a conversation? Does the touch sensor do not work when bringing the phone during a conversation to the ear? Call how you want but the problem is one and decide it here!

Why your smartphone started not to turn off the screen during a conversation, the reasons as always a lot, as it is electronics and what else. This is not a grandfather TV and no calculator and a whole computer in your pocket. In addition to the electronics of which your smartphone stuffed, there is still software The electronics responsible for the correct operation. We will talk about the program part initially, since this is the easiest method to correct this problem about which we are talking in this article. For some reason, not known reasons in your smartphone on board whose Android may arise some miracles, call it. In general, for some reason, it could simply turn off your sensor responsible for approaching the phone to your ear or head. Let's check if it is and if everything is in order, proceed to other methods of correcting this situation with the approximation sensor.

We turn on the program that is responsible for the approximation sensor.

It is very easy to enable this option and since the Android system is different, I mean the name and release number. Also, the menu may differ but not critically, if you enable logic, you will find the path before this setting, if it is of course different from the described below:
We go to the "Settings" usually the designation of the gear icon. In the settings we find item " System applications"The picture below:

Going to "System Applications" find the "phone" item, it is shown in the form of a square of green with a tube, in some versions the name may be "calls", the picture below:

Included in the "phone" subparagraph and find the menu item "Incoming Calls", the picture below:

I got to the final stage where in the "Sensor of the approximation" item must be included so that the slider be with the right and caught fire the color of your smartphone menus provided it. I hope that this option will correct your KU problems with the screen disconnecting when talking, the picture below:

Another way to get to the program inclusion of the approximation sensor.
If you did not help you about which wrote above or you do not have the phone model or more precisely android systems. In this case, there is another way to go to "calls" and continue to click "Settings", it is as always as always as a gear, the picture below:

How to enter the "Settings" item in it will be another item called "Incoming Calls", it is also needed, the picture below:

In the "Incoming Calls" item, we are looking for a cherished switch that may be turned off with you and because of this and there is a not convenient situation when talking. The name of the switch "Sensor of the approximation" which should be turned on, which means it should burn with your smartphone issued to it by it.

To all the above, I can add if it did not help you not one of the options, but you found where the "Sensor of the approximation" is turned on, try to turn off the slider goes and turn on again. Such manipulations can help in some cases, it rarely happens, perhaps it is your case.

Programs for software reset and adjoint sensor settings.

If you did not help or your approximation sensor is turned on, but the situation did not give the result from the above, it happens that the "approximation sensor" menu is not at all in some models. Then I can offer you to try to reflect the settings of the "approximation sensor" as well as calibrate it. To do this, go to Google Play. And download the utility "Reset Sensor" it is called. Next, it is not difficult to figure it out as this utility is intended only to reset the settings of the "approximation sensor" and its calibration. The whole procedure will be called it so happening a few steps. Every step it will be written that you need to do, wave your palm in front of a smartphone, close the sensor and so on. If you have any questions, write in the comment below, listen and answer necessarily. Below can go to the store and get acquainted with the utility:

Consider other reasons are not software.

It is located "Sensor of the approximation" at the very top of the smartphone, to immediately understand that the user does, raised to the ear or the smartphone turn over (cool, rotate) as you want to call. Even if the phone lies on the table, the sensor is aimed at what kind of object and when you took it, turned it, the sensor it determines and causes the menu to rotate, depending on how you hold the phone, top legs or along.

If you glued a protective film on a smartphone.

If you have stuck a protective film on the phone, then it may interfere proper work Sensor. Look at how stuck it is exactly and does not interfere with the sensor. The sensor is located as wrote at the very top, the picture below:

The sensors can be located as two and one of them is the one that is needed, just alone, it is possible that the camera can work in the sensor space, we look at the model of the smartphone. I do not postpone the option with a film and check carefully, we also do not exclude the options:
a lack of random access memory.
Problems with firmware.

Lack of RAM.

The shortage of RAM, not confusing with physical, can also be checked in the smartphone settings at:

Settings\u003e Applications\u003e Working.

At the very bottom after the operating applications shown on the smartphone, it will be shown how much "RAM" is used and freely, the picture below:

If the RAM is missing, it can affect any work of the smartphone as a whole and not just the "approximation sensor". Freeing memory is possible that the sensor will work as it should be supposed if the reason was in this.

Problems with firmware.

It is not uncommon that the "approximation sensor" prevents the correctly not correct firmware of your smartphone correctly. Over time, bugs begin in the firmware due to litters. Try writing a programmatically smartphone let's say utility CCleanerwhich can be downloaded in the Google store, just below the button. Also update it if there are updates, it does not interfere if it does not help the software reset to the factory settings, I wrote about this in the article Link below:

Mechanical impact (blow, fall).

Mechanical impact implies such options as a drop in the smartphone, hitting it into something (waved his hand, the bus slowed down sharply about the handrail hit), many options like you can hit the smartphone. In the smartphone as above, I wrote a "approximation sensor" and it looks like this, here too, it is necessary to judge the model, the picture below:

With this option, the problem may occur as a shift of the sensor itself or the release of the loop from the slot on the smartphone scarf. You can hardly eliminate such a malfunction of the house, and you should not climb wherever you are not at once. You do not know what you will be waiting for you when you will disassemble your smartphone, how to disassemble it and so on. Of course you can see it all on You Tube But believe me on the word that even such specialists who have seen on the video and not one then bring their smartphones and not only with this problem of the sensor.

Moisture getting inside the housing.

Moisture falling inside the smartphone is also not uncommon and with this problem, too, do not cope with yourself. In short, I will describe what happens to the phone when it is drowned. Contacts with time begin to oxidize and bad current conductivity begins or no passivity at all \u003d)))) actually with such a problem exactly call +7 950 002 35 21. Located questions and want to get a qualified and free answer on them? Write that you wanted to know on this article in the comment below and within a few minutes I will answer you.

and goes out when calling and does not turn on. What to configure and how to correct?

Many users face a problem when phone either tablet Na android database Begins to capricious. It seems that nothing happened that could cause a malfunction, and it works not as it should.

For example, problems with the fact that the screen illumination is either its power on / off function, etc. Do not work correctly. The reason why may be:

1st: Software failure - i.e. The problem lies in the failure software

2nd: Hardware failure - i.e. The problem lies in the "hardware" (that is, it is required to replace or restore the spare parts of the gadget)

However, do not rush to get upset - in 90% of cases with problems operations of the power supply control system, backlight adjustment, display / off display smartphone A EY tablet and on the basis of Android is to blame software failurewhich you can completely fix on your own.

Correct the program failure:

Method 1.Pretty simple - come in "Settings", find there « backup and reset "in which you choose full reset Settings with deleting all data. Be careful, the use of this method is often effective, but entails the removal of all photos, contacts, passwords, music, games, video, and in general, all the information stored on your smartphone E or tablet E. Therefore, pre-save everything you need by connecting the gadget to the computer. If this method does not suit you, or if the problem is not eliminated after it, see Method 2..

Method 2..

Based on solving problems with the screen telephone ov i. oS tablet based on Android method Implementing additional software. Utilities controlling all processes inside gadgets. Today, there are quite a lot of them, however, the fewer functions contain an application, the greater, as a rule, it is effective. Best controls the system functions, adjusts, and fixes everything possible mistakes Settings and synchronization is small, and easy to handle, free utility for Android devices. Download app from Google Play and watch it additional options In the description you can. After installing the application, it remains only to run. Next, from you, in principle, nothing more needs. The application will fully take control of the device functions. (By the way, in addition to all other things, the gadget will begin to charge 20% faster, and it will also significantly increase its productivity, which will reflect on the boot speed and work of all applications, games, and the system as a whole. On average, after scanning, the system works on 50% faster.)

Method 3.

Changing the software device, or, as it is also called "Pere firmware ".This methodAs a rule, requires certain skills and is solved by means of contacting the service center. To independently implement this task, you need to contact the manufacturer of your device, download the utility needs for the firmware and the firmware itself, after which reinstall it on your gadget.

If not one of the ways did not bring the results, unfortunately, you will have to contact the service center for repair and yours tablet A EY smartphone a.

On the smartphone either android tablet Does not go out or backlight. Or the smartphone screen goes out when calling and does not turn on.

For the iPhone screen repayment function, the approximation sensor is responsible during the conversation. He triggers when it covers anything. During the conversation, this "something" is the head of a person to which the iPhone is applied. Thus, if the iPhone screen does not go out during the conversation - the approximation sensor is to blame. About how to understand why the screen does not go out during a conversation on the iPhone told in this guide.

Stick a piece of scotch to the approximation sensor

The most often problems with the approximation sensor occurs after replacing the screen on the iPhone. In senses, the sensor brings one multiple times proven method. On the sensor, you need to stick a small piece of transparent tape, and then paint the tape with a black marker.

Masters service centers It is also noted that instead of scotch, it is more efficient to use a piece of stationery with a length of about 5 mm. It is required to stick between light and approximation sensors, after which the problem with the on-screen iPhone screen will disappear during the conversation.

Of course, to gain access to the iPhone sensor will have to be disassembled. You can do it with your own hands. In the instructions submitted below, the analysis of various iPhone models is shown in detail.
