If the battery is depleted or is not charging properly, the screen may remain dark when you attempt to turn it on. In some cases, an overloaded cache or corrupted data within specific applications can contribute to the malfunction. Identifying the root cause is crucial before proceeding with any troubleshooting steps.
How can I perform a force restart on my Samsung S20?
Performing a force restart on your Samsung S20 is a simple process that may help resolve the black screen issue. To do this, press and hold the Volume Down button and the Power button simultaneously for about 10 to 15 seconds. You may need to keep holding them until the Samsung logo appears on the screen. This method essentially forces the device to reset without deleting any data.
Once the device restarts, check if the screen issue persists. If the screen lights up and functions normally, you may have resolved the problem. However, if the screen remains black, you may need to proceed with further troubleshooting steps to identify the underlying issue.
What should I do if the black screen continues after a restart?
If the black screen issue continues after attempting a restart, you can try booting your Samsung S20 into Safe Mode. This mode allows you to start the device with only the essential system applications running, which helps to determine if third-party apps are the cause of the problem. To enter Safe Mode, press and hold the Power button until the Power off option appears, then tap and hold on the Power off option until the Safe Mode prompt appears. Tap “Safe Mode” to confirm and restart your phone.
Once in Safe Mode, check if the black screen issue persists. If the screen works in Safe Mode, a third-party app may be causing the problem.
