Pull out the battery and reboot it. Either it's a problem with the system, flashing.

Press and hold the power off button, if it doesn't work, you can directly pull out the battery and restart. If this problem often occurs, it is a problem with the mobile phone, and it is recommended to flash the system. It is normal for Xiaomi phones to have this situation, and half of the mobile phones will freeze or restart.

Press and hold to turn it off, if it doesn't work, you can directly pull out the battery and restart. If this phenomenon persists, it is recommended to flash the system.

Buckle the battery, if you reattach the battery. The only way to contact customer service is to contact you.

I've also encountered a situation where the touch screen fails, and your Changan power button will automatically shut down. If it still doesn't work, pull out the battery.

As long as you don't do it often, it's fine.

Hello. This is because the phone has 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 rubber 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, select all data for backup, and it usually takes 3-5 minutes.

Factory reset: Click the phone menu button - 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.

2.If you are not using a Xiaomi account, you can only enter recovery mode and clear the data. But if you haven't backed up your phone before, all the data in your phone will be erased.

The method is: in the shutdown state, press and hold the volume plus key and the shutdown button, and let go when the boot screen appears, and you can enter recovery. Go to Recovery >Chinese >> Clear Data >> Empty all data
