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

The Black Screen of Death is a term given to a device whose screen is not working. When this problem occurs, nothing can be seen on the phone screen as it is just black, hence the term. The device might 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 in which case 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 battery

What you will want to do first is to make sure that the problem is not caused by a drained battery. To eliminate this possibility you will have to make sure that the battery is fully charged by following the steps listed below.

  • Clean the charging port of the phone using a can of compressed air making sure to remove any dirt or debris stuck in it.
  • 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.

Once the battery is fully charged check if the Huawei Mate 20 Pro Black Screen of Death issue still occurs.

Perform a soft reset

Your phone will usually store the most commonly used data to make it run better. This data however can get corrupted and can cause this problem. If this is what’s causing the problem then you will need to restart your phone as this will usually remove the temporary data stored in the phone. 

  • Press and hold the Power and Volume down key for up to 45 seconds.
  • Wait as the device restarts.

Start the phone in Safe Mode

There’s a chance that an app you downloaded from the Google Play Store can cause this particular issue. This can be due to bugs present in the app or due to compatibility issues between the app and your phone.

  • Press and hold the power button and release it when you see the Huawei logo on screen.
  • After releasing the Power key, immediately press and hold the Volume down key.
  • Keep holding the Volume key till the phone completely boots up.
  • Once the phone boots up,  “Safe mode” should appear on the bottom of the screen

If the screen works in this mode then the problem could be caused by an app you downloaded. Find out what app this is and uninstall it.

Wipe the cache partition of the phone

There are cases when the cached data stored in the dedicated partition of the phone can become corrupted. When this happens this will usually cause certain issues to occur on the phone.

  • While holding the Volume Up button, connect USB charger to the phone.
  • Within a few seconds, your phone will boot into the recovery mode.
