Why is the screen black when you hit **, let's take a look at what the reason is.

When the mobile phone hits**, it becomes a black screen because the distance sensor function is set in the mobile phone system, when calling, the ear is close to the mobile phone screen, the screen will automatically turn off, which is a normal phenomenon, if you don't want the black screen, you can turn off the sensor in the settings.

Because most of the current smart phones are installed with a distance sensor next to the earpiece, when the face is close to the screen, the screen of the mobile phone will automatically go off, and when your mobile phone is far away from the face, the mobile phone screen will light up again, which is to save the power of your mobile phone and increase the time you use the mobile phone. Under normal circumstances, hit **, cover the top of the screen with your hand, the phone screen will automatically dim, take away your hand, and the screen will light up again.

So, 1) The reason for the black screen could be a protective film or something covering the proximity sensor. You can cover the sensor in the upper left corner of the phone with your finger and let go, if it succeeds, this is the problem.

2) The proximity sensor is faulty and needs to be replaced.

3) The reason for the software: It may be in the settings, the sensor is not set properly, you can go to the "display" under the settings of the mobile phone, the sensor verification item, and the verification may return to normal.

Xiaomi mobile phone is connected to the total size of the screen is bright,There are about three situations,The situation and solutions are as follows:

1. Please confirm whether the mobile phone is using the original film, if a non-original film is used, because the non-original film has not been tested for compatibility, it may affect the function of the mobile phone sensor. It is recommended to remove the film and see if it can be used again.

2. If there is third-party calling software installed on the mobile phone, it is recommended to uninstall the software first, and then observe whether it can be restored.

3. Please check whether the screen is stained, if there are stains, the pants may affect the function of the sensor, it is recommended to use a soft cloth to wipe the screen clean and use it to view.

Hi! This is because Xiaomi phones have a proximity sensor on the top, and when you are talking and the top of the screen is blocked, the screen will go black. When there is no covering, it will be lit. This is to achieve the purpose of saving electricity. All major touchscreen phones have this feature.

If your phone has a black screen when the proximity sensor is not obstructed when you are talking, it is recommended that you restart your phone and try to see if it is normal. Or check to see if your protective film is blocking the proximity sensor above.

Still can't work, it is recommended that you try the following operations in the normal state of your phone:

1. You calibrate the proximity sensor.

Enter * on the dial-up screen

2.Select the twelfth item "Proximity Sensor Test" in the hardware test that pops up

3.Click Start Calibration (Note: Do not obscure the proximity sensor during calibration).

4.The calibration passed, and it was successful! (You can dial and set the anti-false touch mode to test whether it is normal).

5. If the calibration fails, you can tear off the film on the right side of the MI character and try to recalibrate it.

6. Try to restore your backup to factory settings.

Back up data: Go to Security Center > Backup > Create Backup, and select all data for backup, which usually takes 3-5 minutes. Factory Reset:

Tap the phone menu key - System Settings - All Settings - Backup & Reset - Factory reset - Turn on Delete Apps, turn off Format SD card, and click Reset Phone below.

7. If you don't need this function of the proximity sensor, you can turn off and enable the proximity sensor in the call-menu key-settings-status setting when calling.

I am happy to answer your questions: the first reason may be due to the distance sensor turned on, you can turn off the "enable the distance sensor", enter the system "settings" - "programs" - "**" - "answer status" - "enable the distance sensor" - "off" (ps: remember to leave the part of the sensor empty when sticking the film, so it is better).

Reason 2: Don't block the photosensitive dust only hole when talking (there are two on the left side of the earpiece), and the screen will turn on when you take it off your ear, you can try it. The third reason may also be due to the problem that the sensor is blocked by the mobile phone film, and it is good to tear off the protective film of the Xiaomi mobile phone 3. Reason 4: If there is no way to solve this problem, it may be that there is a problem with the hardware, and you can only take the mobile phone to the after-sales test.
