The phone quickly goes blank the screen how to set up
Setting hibernation using native Android tools
You can adjust the time after which Android turns off the screen and goes into sleep mode due to user inactivity in the system settings. To do this, you need to go to the settings of your smartphone or tablet, although more correctly it should sound like “go to the Android settings” and select the “Screen” section, where in the “Sleep mode” subsection set the required time or turn off this option altogether, if the option to turn it off is provided device manufacturer.
The screenshots show the timeout settings of the Huawei MediaPad T3 8 tablet, in which there is no option to disable sleep mode. In other gadgets, this can be the item “Never” or “Disable sleep mode”.
This is the easiest way, but far from the most rational, because in this case, the timeout is set for all installed applications. If we need to set its own waiting time for each program or completely disable the transition to sleep mode while a specific application is running, then we will have to use special utilities.
Configuring screen off by third-party means
A large number of Android sleep management apps can be found on Google Play. Let’s consider the most popular ones.
The phone screen goes off quickly what to do
In most smartphones and tablets running Android, the screen turns off after 30 seconds and the device goes into sleep mode if the user has not performed any actions with the device during this time. This setting is set by default by the manufacturers in order to save battery power. the most power-hungry element in a gadget is the screen on.
Smartphone display does not turn off when talking on iPhone
Proximity sensors in smartphones from Android and iPhone do not differ. Sometimes the sensor stops working on the iPhone due to the fact that the owner decided to change the old film on the screen. If so, then you need to look for another. It is not suitable for your device. If the screen on the device goes blank during a call, try doing a factory reset. Do it using iTunes without downloading a backup. If after these actions the screen does not go out during a call, the problem may lie deeper. And the device needs repair.
Proximity sensor malfunction in iPhone
Let’s consider the principle of factory reset via iTunes. To do this, you need a USB cable to connect your smartphone to your computer. PC can also be used with Windows.
ITunes download page
But you need iTunes, which can be downloaded here. https://www.Apple.com/ru/iTunes/download/.
Plug the USB cable into your smartphone
To enable the desired mode on the phone when connected to a PC, press the Home and Power buttons together;
Press the Power and Home buttons together
The buttons must be kept until the screen turns off;
Wait for a black screen on your phone
Computer screen message
Click the “Ok” button and select one of the “Update” or “Restore” items;
Select one of the items on the computer screen
Another message will appear on the screen, which will warn that recovery will delete all data on the smartphone;
Confirm your decision to update your iPhone.
IPhone Data Recovery Process
The process of restoring your smartphone to its factory settings will begin immediately. When it finishes, try calling again to check if the proximity sensor is working.
What to do if the screen stays on during a call on Android
Let’s try to enable the proximity sensor in your Android smartphone. It is quite possible that due to the above reasons, it was turned off as a result. Therefore, we need to open the Android settings. In particular, this manual will be useful for popular Xiaomi devices.
If the phone screen does not fade during a call, you need to activate the proximity sensor:
- In the main menu, click on the gear button. to get to the smartphone menu;
Select the gear on the home screen
Then find the item called “System Applications” in the settings and select it;
Click on “System Applications”
Activate the item “Proximity sensor”
Now call your spouse or friends to test the proximity sensor in conversation. If it was already turned on in the settings, or even after turning it on, it did not start working correctly, read the solution options below. Only now it is not clear why the manufacturer allowed users to disable it at all. You might think that someone might need to turn it off.
A small and lightweight application called “Screen never dies” disables sleep mode and does not allow the screen to go out while preselected applications are running.
Working with the utility is extremely simple. launch it and mark those applications for which the screen will be always on.
The utility correctly detects the software installed on the smartphone / tablet, is free and intuitive.
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.
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 light, 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. 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 blood 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.
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.
Operating system errors
If the device freezes and does not turn on after that, then it is highly likely that the main problem lies in the operating system. Android OS (this is especially true for older versions) is not famous for its stability, so sudden errors may occur regardless of the brand and model of the smartphone.
In such situations, not everything is unambiguous, because in most cases, when the screen does not turn on, and the problem arose after freezing, you just need to pull out the battery for a couple of minutes, after which, most likely, the device will start without problems. Unfortunately, it is not always possible to solve the problem in this way, because sometimes the phone does not start even after that, and some devices are equipped with a non-removable battery (use the reset button located on the smartphone body). Where to find it, read the instructions.
If all the tips that were given above could not help you, then you will have to reset the device settings to factory settings. Unfortunately, all your data will be deleted, but the good news is that the operating system will start functioning normally again. Follow the instructions below:
- Hold down the Volume Up and Home keys.
- Press the power button without releasing the pressed keys.
- In “Recovery Mode” you can roll back to factory settings. This process is individual for each smartphone, so you should look for instructions on the Internet.
Now that you have learned what to do if the screen of a smartphone released by Samsung does not work, you can take stock. Do not disassemble the device yourself if you are not sure of the success of the actions. Entrust it to the professionals working in the service centers. Only they can correctly diagnose a breakdown and replace a failed module.
Service centers often receive questions about what to do if the screen does not work after the phone has been dropped. In fact, if the reason really lies in the fall, then it will definitely not be possible to solve this problem on your own. The phone can only be repaired by contacting the service center.
It should be noted that when the device falls, several damage options are possible:
- Damage to the display. Such situations can be solved in only one way. by replacing the display, but it is almost impossible to do this on your own. It is best to take the phone, the screen of which is off, to a Samsung service center, where specialists will replace it with the original one.
- Damage to the screen control chip. If the screen of a device from Samsung does not turn on, this does not mean that the display is to blame for everything. It is not uncommon for people to replace the screen, but the problem is still not solved. Replacing the microcircuit is quite cheap, which allows you to solve the problem as quickly and efficiently as possible. It is not recommended to do this on your own, as you need specialized equipment for re-soldering the boards.
- Damage to the connection of the connector to the printed circuit board. This situation is as simple as possible. To solve it, you only need to disassemble the smartphone, the screen of which has gone out, and insert the detached part in its place. 90% that this method will help your device.
How To Fix Black Screen Problem on Samsung Galaxy, Fix Black screen No Display Phone
It is worth mentioning that there are other rare problems as well. which can only be identified at service centers. Contact the experts if you have a screen on your Samsung phone. Samsung smartphones do not fail as often as they say.
Let’s first analyze commonplace problems due to which the screen may stop working. Let’s start with the difficulties that can be associated with the battery. Most often, the battery simply does not receive the proper amount of energy from the charger. On Samsung, this can happen as a result of a faulty charger that stops working properly due to a burnout of the microcircuit inside the power supply.
Such cases are not rare and happen all the time, as a result of strong voltage fluctuations. With a significant increase in the input voltage, the board burns out. It’s good if the charger suffers, and not the device itself.
It is also worth mentioning that the battery may fail, but this rarely happens on devices from this company. This problem can be solved by simply replacing the battery with a new one. You can do it yourself, just choose the right battery.
Why the screen goes blank on Samsung
Remember, if the screen on your Samsung phone is not working, then it’s time to contact a service center. If the mobile body looks completely intact, there are no slightest cracks, there are no smudges on the display, then the reasons may be as follows:
Sometimes the display on a Samsung phone stops working due to the fact that the screen itself, that is, the matrix, is damaged. Most modern smartphones from Samsung (A-series: Galaxy A3, A5, A7; S-series: Galaxy S5, S6, S7, S8; also some J-series models) use amoled matrices, one of the disadvantages of which is fragility. If they are damaged, as a rule, outwardly there may be no signs, since small cracks are under the glass and can only be viewed from a certain angle. The outer glass very often remains completely intact, the phone boots up, makes sounds when touched, you can even pick up the phone from memory for an incoming call, but there is no image or backlight, only the touch buttons at the bottom of the screen next to the home button are lit. Do not try to make repairs yourself: not only is it difficult, but you can also aggravate the breakdown by damaging the loop of the touch buttons, the back glass cover, etc. Remember, our service center will solve your problem in a matter of hours: we always have the right original parts. If even you have the slightest doubt, then do not risk it: immediately take the phone to the masters, because only they will carry out a high-quality replacement.

Often a black screen appears in a Samsung phone: if the microcircuit that is responsible for controlling the screen, or some components in its strapping fail. It is quite difficult to replace them with improvised tools.
In rare cases (one in a thousand), the display does not turn on in a Samsung phone due to the fact that it has recently “landed” on a hard surface and the connector has come off the main PCB. In our center, it can be done in the shortest possible time or even in the presence of the client.
Of course, there may be a completely different kind of problem that can only be identified after a thorough diagnosis.
Not everyone monitors their smartphone closely. Quite often, unforeseen situations arise due to the fact that the device does not turn on or the screen does not work on Samsung. This can happen for completely different reasons, ranging from ordinary mechanical damage to factory defects. Let’s take a look at the most common reasons why a smartphone stops functioning correctly.
What to do if the backlight of the screen does not work correctly on a smartphone or tablet, or the display does not turn off when it should be. Or, the smartphone screen goes blank when called and does not turn on. What to set up and how to fix?
Many users face a problem when an Android phone or tablet starts to act up. It seems that nothing happened that could cause a malfunction, but it does not work as it should.
For example, the device has problems with the screen backlight or its on / off functions, etc. do not work correctly. This may be due to:
1st: Software failure. i.e. the problem is a software failure
2nd: Hardware failure. i.e. the problem lies in the “hardware” (that is, it requires replacement or restoration of spare parts for the gadget)
However, do not rush to get upset. in 90% of cases with problems with the operation of the power supply adjustment system, adjusting the backlight, turning on / off the display of a smartphone or tablet based on Android, a software glitch is to blame, which you can easily fix on your own.
Quite simple. go to “settings”, find “backup and reset” there, in which you choose a full reset with the deletion of all data. Be careful, the use of this method is often effective, but it entails the deletion of all photos, contacts, passwords, music, games, videos and, in general, all information stored on your smartphone or tablet. Therefore, pre-save everything you need by connecting the gadget to your computer. If this method does not suit you, or if the problem persists after it, see Method 2.
It is based on solving problems with the screen of phones and tablets based on Android by introducing additional software. Utilities that control all processes inside gadgets. Today, there are quite a few of them, however, the fewer functions an application contains, the more, as a rule, it is effective. Best of all controls system functions, corrects, and fixes all possible settings and synchronization errors is a small, easy-to-use, free utility for devices based on Android Multi Cleaner. You can download the application from Google Play and see its additional options in the description HERE. After installing the application, all that remains is to launch it. Further, from you, in principle, nothing else is required. The application will completely take over the control of the device’s functions. (By the way, among other things, the gadget will start charging 20% faster, and its performance will also significantly increase, which will affect the loading speed and operation of all applications, games, and the system as a whole. On average, after scanning, the system works on 50% faster.)
- In addition, it is worth cleaning the system with NORMAL antivirus. Best of all, Kaspersky Anti-Virus copes with this task, which can be downloaded HERE. Unlike the “multi-cleaner”, the software of “Kaspersky Lab” is paid, therefore, if you do not have the opportunity to install such protection, you can skip this step
Changing the software of the device, or, as it is also called “flashing”. This method, as a rule, requires certain skills and is solved by contacting the Service Center. For the independent implementation of this task, you need to contact the manufacturer of your device, download the necessary utilities and the firmware itself for the firmware, and then reinstall it on your gadget.
If none of the methods brought results, unfortunately, you will have to contact the Service Center to repair your tablet or smartphone.
Xiaomi screen turns off too quickly after an incoming call, or does not turn off at all. what to do?
A proximity sensor is installed on all Xiaomi phones, which plays an important role. turns off the screen.
There is a possibility of a software failure or mechanical failure of the sensor, in which normal operation stops. In this article, I will consider the most popular cases and methods for resolving them.
Calibration of the sensor through the engineering menu Xiaomi
To enter the engineering menu of Xiaomi, open the applications for dialing a phone number to make a call, but dial the following symbols: ### You will be taken to the engineering menu, we are interested in the item “Proximity sensor”, select it. The health checker starts. The upper digits should change to 0 as the obstacle approaches the place where the sensor is installed (next to the speaker). If without an obstacle it has a digital value, but as it approaches it changes to 0, then the sensor is working properly. If not, please calibrate.
If the upper digits do not change at all, then either it is out of order, or something is interfering with it. Often, a protective glass that is not glued correctly, or dust on the sensor, or water can become an obstacle to normal operation. If the protective glass is stuck on, remove it and check the sensor again. Make sure there is no dust or other foreign objects near it.
If no manipulations have led to a result, there is a high probability of mechanical damage to the sensor and the need to repair the smartphone.
In this case, you need to turn off all functions that are tied to the sensor. Follow the above path and disable the “Proximity Sensor” option in the “Phone” application.
The screen goes out when there is an incoming voice call on Xiaomi
When a full-screen notification of an incoming call appears, the Android operating system turns on the sensor. In the normal case, it detects that there is nothing near the screen and therefore the display is activated. However, if the phone is in your. or lies on the table with the screen facing down, there is sound, but no picture. For the same reason, during a call, the screen is turned off to save energy, because you cannot control Xiaomi at this moment.
In case of a software glitch, when the screen goes blank and does not turn on during a voice call, you can do the following:
- Turn off and then turn on the proximity sensor
- Calibrate it
Let’s try a simple option first and turn it off and then turn on the sensor in the hope that this is an accidental software glitch. To do this, go to “Settings”, find the “System Applications” menu. Now find “Phone”. Select “Incoming Calls”. We are interested in the Proximity Sensor menu. Disable it and then enable it again. For reliability, restart your phone in the usual way. In most cases, this helps, provided that there was no mechanical damage (the phone did not fall, was not flooded with water, was not exposed to extreme cold or hot temperatures). If this procedure did not help, we will try to calibrate the sensor using the engineering menu.
The display does not go out during a call on Xiaomi
If the display does not go out when you are talking on the phone and hold it to your ear, the problem is exactly the same. you need to follow the procedure described at the beginning of the article.
You can check the performance in a simple way, for which you need any other phone with a camera. Turn on the camera on it and point it at the sensor being tested, then call Xiaomi. During an incoming call, the sensor will turn on and you will see its flickering on the screen of the second phone. If there is no flickering, then the sensor is either disabled at the operating system level, or is broken.
The most popular reasons that lead to the fact that the screen either goes out too quickly or does not go out at all:
- Poorly adhered protective glass, there is either an air bubble or a large piece of dust at the sensor location that interferes with normal operation
- If the native or protective glass is broken, and the crack passes over the sensor, this can lead to its inoperability.
- Dirt, dust and any other foreign matter will also interfere with its operation, clean the screen
- During an incoming test call, try to slightly squeeze the screen and body in the place of the intended location of the sensor, but without covering the sensor itself with your hand. If the result appears, it means that the glass is peeling off, or a gap has formed between the front and back of the Xiaomi case. This problem is solved by repair in a service center
