What about Xiaomi Redmi K20 Pro black screen?

If the screen can light up normally during the boot process, but a black screen appears after entering the system desktop, this situation is often caused by system problems, such as the system desktop program is not loaded. This situation needs to be solved by restoring the factory settings of the mobile phone once. First, when the mobile phone is turned off, press the volume increase button and the power button at the same time to enter the rec brush interface, and select Double Clear in this interface, that is, erase all data, and then restart the mobile phone. If you have any problems caused by system failure, please click. If the phone keeps black after pressing the power button, it is necessary to consider whether the phone screen or backlight module is damaged. You can't handle this hardware problem yourself, you can only send it to the official after-sales service.
