How to fix Android black screen error

2. Clean the charging port section. Dirt and dust may cause the phone's charging performance to be maximized. If necessary, gently blow dust out of the charging port. Then, plug it in again and let the charger sit for about 10 minutes. Next, reboot the machine.
3. Wait until the machine is completely out of battery, power down and then plug in the charger, restart the device when fully charged. If the black screen problem is caused by a system error, this action will help the machine work properly again.

5. Force restart the phone. Lots of system errors can be solved this way. How to do it depends on each Android device you are using. Plug in the charger, wait about 5 minutes and then perform Force restart.
6. If possible, remove the device's battery, wait about 30 seconds then insert the battery and restart the device.
7. If the device comes with a pen, remove the pen to see if this is the cause of the black screen. If correct, go to Settings> General management> Reset and select Auto Restart .
8. Start the phone in Safe mode. Safe mode allows you to navigate your phone to reboot, clear cache, or do other actions to get rid of the black screen issue.
