What about the black screen of Huawei mobile phone?

If you are using a Huawei mobile phone, and the phone has a black screen during use, please check it according to the following methods.

Check the charging status

Using the mobile phone while charging may cause the phone to overheat, resulting in abnormality. I suggest you try to avoid playing with your mobile phone while charging.

Check sensor

Black screen when talking on mobile phone. In order to increase the battery life of the mobile phone, if the distance sensor is blocked during the call, the mobile phone will automatically close the screen and reopen the screen after being far away. The mobile phone reaches the set sleep time. When the phone reaches the set sleep time, it will automatically close the screen and manually open the screen when re-entering.

Check the storage space

If the storage space is less than 10%, the system performance will drop sharply.

Forced restart

I suggest you forcibly restart your mobile phone. If it cannot be restarted, please bring the purchase voucher to Huawei Customer Service Center for testing and processing. If it can be restarted, it is suggested to continue the investigation according to the following scheme to avoid the phenomenon of jamming in use. Tip: If the data has not been backed up before, there is a risk of data loss during maintenance.

Replace screen

If the above methods can't solve the problem, I suggest you change the screen.
