1. Press and hold the volume down and power button until the Android System Recovery screen appears.
2. Navigate using volume keys and select using the power key.
3. Select Wipe cache partition and allow to complete.
4. The device should automatically reboot, select the reboot option if it doesn’t.
In the vast majority of cases, this has addressed the black screen issue. This usually indicates an app is causing stability problems. If this is the case for you, begin troubleshooting apps by disabling or uninstalling them until the device works normally again.
Factory reset to fix black screen issues
If the previous step doesn’t work, the only other option to fix a black screen after turning on an Android device is a factory reset. This will wipe the device of all your personal data so should only be attempted as a last resort and after backing up your data if possible.
1. Power off the device.
2. Press and hold the volume down and power button until the Android System Recovery screen appears.
3. Navigate using volume keys and select using the power key.
4. Select Wipe data/factory reset and confirm.
5. The device should automatically reboot or select the reboot option if it doesn’t.
If this final step fails, it is likely a hardware issue and you should follow that up with your provider.
