That said, we have included 07 solutions to address this issue. All you have to do is follow the instructions and apply them to your Z Flip 3. Let’s get started.

Fix 01: Restart the Device

Screen flickering can be a result of temporary software glitches, and restarting the device will help you resolve this issue. A restart does this by clearing the system’s temporary memory (RAM) and stopping all the running processes.

  1. Press and hold the Power button and the Volume Down button simultaneously.
  2. Continue to hold both buttons until the device vibrates and the Samsung logo appears.
  3. Once the Samsung logo appears, release both buttons.
  4. Wait for your device to restart.

Fix 02: Turn Off Adaptive Brightness

As you may know, the Adaptive Brightness automatically adjusts the brightness of your device’s screen based on the surrounding light conditions.

If this feature malfunctions, it will result in constant fluctuations in screen brightness, which can cause the screen to flicker. 

If this is the case, disabling Adaptive Brightness will solve the screen flickering issue. Follow these steps:

  1. Open the Settings app.
  2. Scroll down and select Display.

Fix 03: Disable HW Overlays in Developer Options

Hardware Overlays (referred to as “HW overlays”), allow apps to directly control specific screen compositions.

This can enhance the performance of your device by allowing smoother transitions and reducing the load on your CPU. However, if a malfunction occurs, then it can cause your screen to flicker.

Therefore, you need to disable HW overlays to fix this, and here is how:

  1. Go to Settings.
  2. Scroll down and tap on Developer options.
  1. Scroll down until you find Disable HW overlays.

  1. Toggle it on.

Fix 04: Boot the Device Into Safe Mode

Booting your Galaxy Z Flip 3 into Safe Mode helps you identify if the screen flickering issue is caused by a third-party app.

Once you’re in Safe Mode, you need to check if the screen flickering issue still persists. If it doesn’t, then a third-party app is likely causing the problem.

You can then start uninstalling recently installed or updated apps one by one, and check after each uninstallation if the problem is resolved.

Here’s how to boot your device into Safe Mode:

  1. Press and hold the power button until the Power menu appears on the screen.
  2. Then, tap and hold the Power off option until the Safe Mode appears.

Here’s how you can update your Galaxy Z Flip 3:

  1. Go to Settings, and then Battery and device care.
