Samsung Z Flip 3 /4 Cover Screen Not Working, How to Fix?

Try the solutions I’ve mentioned below and check which one can spell out success for you. After applying a fix, check if the problem has gone. If it’s still there, keep trying other solutions until the problem is solved.

Fix 1: Change the Brightness Value

As we discussed a few moments ago, a low brightness can make the display look like it is not working. You should set the cover display brightness value to the max and check if you can use the cover display.

To change the brightness value, open the Settings app and select the Display option. From there, you can change the current brightness level.

Fix 2: Reboot the Device

Although this solution may sound trivial, it does the trick most of the time. Rebooting the device clears temporary memory and refreshes all the running processes. It can resolve the conflict with the multiple displays (if there are any) or system glitches, and you can get the cover display in a working state.

Fix 3: Reboot the Phone in Safe Mode

Third-party apps are useful, but many often create different kinds of problems on the device. Most of the time, this is the reason why your phone freezes, crashes, or lags. If a third-party app has anything to do with the cover display, you should remove it.

If unsure if a third-party app is causing the problem with the cover screen, you should reboot the phone in Safe mode. In short, it disables all downloaded apps and loads only the original software with your device. So, if the cover display works in the Safe Mode, you should remove the culprit, a third-party app. You can uninstall third-party apps one by one so that you can identify the defective third-party app.
