What to do if the screen on your device is flickering

Restarting the device is often the quickest and easiest way to resolve software issues.

• via Power Key: Press and hold the Power key, and then tap Restart. Tap Restart again to restart your device.
• via Notification panel: Swipe down from the top of the screen to open the Quick settings panel >  Power icon, > Restart > Restart.

Booting your smartphone in safe mode is also another option to find out if the screen still flickers or not. Safe mode is like a diagnostic tool to help identify the problems on your device.

Step 1: Turn off your device then power it on.

Step 2: When the Samsung logo appears by itself, press and hold the Volume Down key.

Step 3: The device will switch on in Safe mode. Safe mode will be displayed on the bottom left of the screen.

• If the issue is gone in Safe mode: One of your recently downloaded apps was likely the cause of the problem. 
• If the issue still exists: Downloaded apps may not be the cause of the problem. You may need to reset the phone or tablet to the factory setting.

To exit safe mode, restart your device

If your screen is still flickering, try adjusting your brightness settings.
