Why is the Cover Screen Not Working on Samsung Galaxy Z Flip 3 / Flip 4?

There could be many reasons the cover screen may not respond on your Samsung Galaxy foldable phone. Many times, people set the brightness for the cover screen too low and forget to change the brightness value. It makes the cover display contents too darkish that it appears as if the cover display is not working. Hence, you should check the brightness value for the cover screen.

A software bug can also break some functionalities. It could be why the cover screen does not function well on your Samsung Galaxy Z Flip 3 or Galaxy Z Flip 4. We can’t eliminate the possibility of a hardware failure. Sometimes the hardware components fail, which can cause serious problems to the device.

Before you take the device to the Samsung authorized service center, here are a couple of solutions to fix the issues with the cover display on your Samsung Galaxy foldable phone.

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.

To reboot the device, press the power button until you see the power menu. Tap on Restart and wait for the device to boot. Once the device reboots, check if the problem is fixed. If your answer is yes, Awesome! If the problem persists, try out more solutions.

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.

Here’s how to reboot your phone in Safe mode:

  1. Press and hold the power button until the power menu appears.
  2. Now, touch and hold the Power off icon on the screen until you see the Safe mode icon.
  3. Click Safe mode to reboot your Samsung phone in Safe mode.

Fix 4: Update Your Samsung Phone

There could be a software bug in your Samsung Galaxy Z Flip 3 or Galaxy Z Flip 4, which is not allowing the cover display to work properly. To fix such issues, smartphone companies keep releasing new software updates that also include new features and improvements. Hence, updating your Samsung phone to the latest firmware version can fix the problem with the microphone.

Steps to update your Samsung Galaxy phone:

  1. Open the Settings app.
  2. Go to Software updates.
  3. Tap on Download and install. Wait until the latest firmware is installed.
  4. Reboot your phone.

Fix 5: Perform a Factory Reset

If none of the solutions have worked for you, factory resetting the device can fix the issue if the problem is related to software. We do not recommend this solution at first because it involves data loss. Factory reset removes all the data on your phone, photos, videos, contacts, installed apps, documents, etc. Hence, remember to take a full backup of your phone before factory resetting the Samsung Galaxy Z Flip 3 or Galaxy Z Flip 4.

Steps to factory reset your Samsung phone:

  1. Open the Settings app on your phone.
  2. Go to General management and tap on the Reset option.
  3. Find the Reset button option and tap on it. If prompted, enter the lock screen pin or password.
  4. Click on Delete all and wait for the factory reset to complete. Your device will reboot automatically.
