Fix: Samsung Z Fold 3/4 Cover Screen Not Working

Method 2

If your inner display is also not working or the display is unresponsive, use this method to force restart your device. Follow these steps:

1. Press and hold the power button and the volume down button simultaneously.
2. Keep holding the buttons for about 15 seconds until you see the Samsung Galaxy logo appear on the screen, and then release them.
3. Wait for the device to boot up to the lock screen.

After restarting the device, check to see if your cover display works now and if the issue is resolved.

Fix 2: Boot Into Safe Mode

Booting into the safe mode makes your device go into the default settings and boot into the diagnostic state. This helps tackle any issues with glitches and bugs caused by third-party apps. To restart into boot mode, follow these steps:

1. Press and hold the power button and the volume down button simultaneously.
2. Wait till you see the power off screen pop up.
3. Tap the “Power off” icon until the “Safe Mode” prompt appears on the screen.
4. Tap on “Safe Mode” again to restart into safe mode.
5. Wait for about 30 seconds for the device to restart with “Safe Mode” written on the bottom left corner of the screen.

See if the “Safe Mode” solves the issue and if the cover display works now.

Fix 3: Tap With Your Fingers Gently

With the moving parts of the two halves of the phone, the display connector may get dislodged with an impact or frequent movements, which is not desirable, but may happen.

This may sound gimmicky or skeptical, but many users have written online that it has helped solve their issue magically.

Follow these steps:

1. Open your fold fully.
2. Keep tapping on your inner screen, cover screen, and the device’s back panel.
3. Restart the device and keep repeating this for a while.

After repeating this about five times, it can help solve the issue reported by many Fold users.

Fix 4: Factory Reset Your Device

If none of the solutions has fixed your problem, now there is a chance of some software bugs or unused files that might be causing the problem. So, a hard reset or a factory reset might fix the problem. However, it might be hard for some people to factory reset their devices.

2. Now, use the volume buttons, navigate to “Wipe data/factory reset,” and press the power button.
3. Now navigate to “Factory data reset” and press the power button again.
