How To Fix The Huawei Mate 20 Black Screen of Death Issue

The Black Screen of Death issue is an issue that occurs on a phone whose display is not working properly. When this problem occurs, nothing can be seen on the phone screen as it is just black, hence the term. The device can still be getting notifications, calls, or text messages when this issue occurs or it might not be functioning at all. 

If this happened after you dropped your phone or had your device in contact with water  then it’s very likely that this is caused by a damaged hardware component. If this is what’s causing the problem then you will need to have the phone repaired at a service center. 

If this just happened randomly then there’s a possibility that it is caused by a software glitch. Listed below are the necessary troubleshooting steps that you need to do if this is a software related issue.

• Fully charge the phone with a charging cord and wall charger that have been tested to work on another device.
• If the phone does not charge with a wall charger then try charging the device from a computer USB port.
