Xiaomi MIX3 mobile phone can't be turned on, what should I do?

If the phone has a black screen and cannot be turned on and turned on normally, you can try the following methods:

1, press and hold the power button for more than 10 second, and try to restart forcibly;

2. Confirm whether it is turned off due to low battery. If so, try 15-30 minutes before restarting when using the original charger or charging with weak current (for example, charging with computer USB interface). If the battery is turned off because of low power, the charger may not light up when it is first plugged in, and the breathing light flashes red;

3. If the original power adapter (charger) is plugged in, and the mobile phone is hot without any operation, it is recommended to unplug the charger and take the mobile phone, the original power adapter and the original data cable to Xiaomi Authorized Service Center for detection and treatment;

4. If it is determined that the mobile phone has power, press and hold the volume up+power button or volume down+power button at the same time when it is turned off to see if it can enter the recovery mode and the quick start mode. If you can enter the above two modes, press and hold the power button 10 seconds to try to restart;

5. If the operation in "4" still cannot be started, you can try to clear the data in recovery mode before entering the system: it is recommended to enter recovery mode and select "Clear Data"-"Clear All Data";

6. If the cleared data is still invalid, and the mobile phone has logged into Xiaomi account to unlock BL, it is recommended to use Miflash brush tool to try line brush;

7. If the above methods can't be solved, it is recommended that you go to Xiaomi Authorized Service Center for testing and processing or apply for after-sales service in official website.

note:

1. If you are stuck in the white miter interface for a long time and the word Android is not displayed at the bottom of the screen, it is invalid to press the power button 10 seconds before restarting. It is recommended that you go to Xiaomi Authorized Service Center for testing and processing or apply for after-sales service in official website.

2. Pay attention to clearing the data, and the brush will clear all the data in the mobile phone.
