On Android, the screen does not turn off during a call. Incoming calls are not received or the handset does not pick up when there is an incoming call on a smartphone or running Android
When your iPhone receives an incoming call, its screen will usually light up, prompting you to answer or reject the call. For some users, after installing a new operating system iOS 11 screen does not light up when making a call; You can only hear sound or vibration, and the display itself is just black. In fact, this problem can appear on different iPhone models no matter what iOS version installed. But the ways to solve it will be the same.
Black screen when receiving a call on iPhone
If at incoming call on your iPhone you see a black screen, most likely the system has some kind of glitch, or you have problems with the display. To eliminate problems with the screen, check its functionality in normal mode. If the display works when launching applications, but the screen does not light up during a call, then the problem is not in the screen itself, but in a system error.
The first recommendation is to restart your iPhone. Most often, restarting the iPhone helps solve system errors. But not always... Therefore, if the black screen on your iPhone still lights up when there is an incoming call, you may be using a protective film or glass on the screen, which may cause the proximity sensor to not work correctly.

Under Android control. What to do and how to fix it.
Many users encounter a problem when phone or tablet on Android based starts to be capricious. 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 fact that it is not possible to answer an incoming call, or the device cannot be reached, although the call is coming. The reason for this may be:
1st: Software glitch - i.e. the problem is the crash software
2nd: Hardware failure - i.e. the problem is in the hardware (i.e., replacement or restoration of spare parts for the gadget is required)
However, do not rush to get upset - in 90% of cases there are problems reception system operation voice calls and messages smartphone a or Android tablet is to blame software glitch, which you can easily fix on your own.
Fixing a software glitch:
Method 1. Quite simple - go to "settings", find there « backup and reset", in which you choose full reset settings with deletion of all data. Be careful, using this method is often effective, but it entails deleting all photos, contacts, passwords, music, games, videos and, in general, all information stored on your smartphone e or tablet e. Therefore, first save everything you need by connecting the gadget to your computer. If this method does not suit you, or if even after this the problem is not resolved, see Method 2.
Method 2.
Based on solving problems with communication and network reception phone number and tablet based Android method implementation of additional software. Utilities that control all processes inside gadgets. Today, there are quite a lot of them, however, the fewer functions an application contains, the more effective it is, as a rule. Best monitors system functions, adjusts, and fixes everything possible errors settings and synchronization is small and easy to use, free utility for Android devices. Download the app from Google Play and watch it additional options in the description it is possible . After installing the application, all that remains is to launch it. Further, in principle, nothing more is required from you. The application will take full control of the device's functions. (By the way, among other things, the gadget will begin to charge 20% faster, and its performance will also increase significantly, which will affect the loading speed and operation of all applications, games, and the system as a whole. On average, after scanning, the system runs at 50% faster.)
Method 3.
Changing the device software, or as it is also called "re firmware".This method, as a rule, requires certain skills and can be resolved by contacting the Service Center. To carry out this task yourself, you need to contact the website of the manufacturer of your device, download the utilities necessary for flashing the firmware and the firmware itself, and then reinstall it on your gadget.
If none of the methods brings results, unfortunately, you will have to contact the Service Center for repairing your tablet a or smartphone a.
There are no incoming calls or the handset does not pick up when there is an incoming call on a smartphone or running Android. What to do and how to fix it.
Spontaneous iPhone freezes and glitches, unfortunately, are no longer uncommon. Many people are worried about this, but Apple, it seems, is not going to do anything.
Our reader Alexander described the problem best:
This glitch is really annoying: a black screen appears on the iPhone 7 and 7 Plus. For example, when there is an incoming call, the screen simply does not light up (vibration only and the ringing sound), and only responds to the power button. Click on Home button at least a hundred times, the screen does not light up, but the vibration feedback clicks and that’s all.
It happens periodically several times a day, but I have not identified any sequence leading to this. Honestly, I’m tired of it already, I don’t have the strength to endure this disgrace, I want to throw my iPhone against the wall, it’s infuriating, I’m already ready to sell both.
Such a problem really exists, and the case described is far from the most severe.
Why is this happening
“Black Screen of Death” is a relatively new concept for iPhone users; we have rarely encountered anything like this before system failures. Most often this was solved by a simple reboot or firmware update.
Now almost every user of Apple technology has observed similar failures on their device or on a friend’s device. A black screen may appear on most models, regardless of the iOS version.
There are several main reasons for this strange glitch:
1. Mechanical failure
A black screen often appears on devices that have been in water. Even new iPhones 7 with moisture protection are guilty of this. You don't have to heat your smartphone to do this. It is enough to actively use it in a humid environment, in the rain, or splash the device several times.
No service center will be able to establish 100% that a black screen began to appear on the device after getting wet. However, taking “water procedures” with a smartphone will be another reason to think about the reasons for such glitches.
2. Problematic software
Every year iOS becomes more open; developers can embed their modules into many standard programs. This may affect iOS operation.
Any system update may bring a piece of code that does not fit well with existing applications or settings.
Only complete cleaning Devices with firmware recovery can minimize the chance of a black screen, but not everyone can take such measures. Not everyone wants to turn their 50 thousand iPhone into a testing ground.
3. Battery problems
Service center technicians note that battery problems can often be the cause of a black screen. Old worn out battery could lead to something like this.
On new gadgets, a black screen is often caused by an overheated battery. This can happen even on a fully functional device when connected to the charger for a long time.
What can you do
Unfortunately, there is no advice that helps in 100% of cases. We can offer such methods of “treatment”.
1. First, make sure that you are not using the beta version of iOS, completely from receiving test builds.
2. Charge your smartphone. Do not keep your iPhone on charge all night and stick to using gadgets in winter.
3. Avoid apps that are built into system programs. Now at App Store many add-ons for iMessage, extensions for Safari, informers for the Phone program, third party keyboards and other additions. All of them are built into the system and can affect its operation.
4. Disable the feature Raise To Wake (Settings – Screen and brightness – Raise to activate), which is responsible for turning on the display when the user picks up the iPhone, or Opening by placing your finger (Settings – Basic – Universal Access– Home – Open by placing your finger).
It happens that exactly simultaneous operation These two options lead to system failures.
5. If all else fails, you can reset your iPhone to factory settings and use your smartphone, gradually adding programs from the App Store and making changes to the settings.
Yes, the solution is not the best, but this is the only way to accurately determine what exactly causes the black screen to appear in a particular case.
We wish you not to find yourself in such situations, and if you do, find the right way out quickly. Happy holidays!
If the screen on Android does not turn on after a conversation or does not go off during a call when you put it to your ear, then you should look for the cause of the problem in the work. If it breaks down, the device cannot correctly determine its position in space, so the screen does not light up, but the phone works.

Problems with the screen when making calls on Android
Main function proximity sensor is automatic switching on and turning off the backlight during a call. This allows you to save battery power and prevent accidental pressing of your ear or cheek touch screen your gadget.
If your Android device does not turn off during a call, or the screen does not turn on after the call ends, then you should look for the problem in the operation of the sensor. The reasons may be as follows:
- Poor visibility (covered/covered protective film or cover).
- Lack of RAM.
- Problems with the firmware.
- Moisture ingress.
- Mechanical impact and damage to the cable or other components.
Before you start programmatically To resolve the problem, wipe the screen thoroughly. Pay special attention to the top part, where the proximity sensor is located. If film or glass is glued to the display, then over time they may lose transparency and also interfere with the sensor.
Then check the call settings - perhaps the parameters are set incorrectly and the sensor is simply turned off. This option Not available on all phones, but worth checking.
- Open Settings and go to “My Devices” or “Options”.
- On the Calls tab, make sure there is a checkmark next to Proximity Sensor.
Increase Also, make sure that the system has enough RAM to run the sensor. Open the list of applications in settings and on the “Running” tab look at how much RAM your phone is using. If you find a shortage, shut down unnecessary applications.
If everything is set correctly in the settings, but the sensor does not work, do backup copy important data and reset Android options to factory condition. If the problem persists after a hard reset, you will have to reflash the phone. If none software methods, including flashing, did not eliminate the problem, it is recommended to contact service center to diagnose hardware faults.
Problems with the screen on Android after sleep mode
Another problem that may arise with the screen is that it does not turn on after sleep mode. It may or may not be black, but the phone works. If you are faced with such a situation, then know that the reasons can also be software or hardware in nature:
- Lack of RAM.
- Problems with the firmware.
- Incorrect operation power buttons.
- Mechanical impact (impact, fall).
- Moisture getting inside the housing.
If the phone does not turn on, but vibrates when there is an incoming call or other actions, then there is a high probability that the problem can be fixed without contacting a service center. Clear RAM from unnecessary processes, completing unnecessary work in at the moment applications. If this does not help, make a backup of your important data and reset the system settings to the factory state.
Increase If a hard reset also does not fix the problem, you will have to reflash the device. It is important not to forget to make a backup copy before each serious operation to interfere with Android.
