What to do if the screen on your device is flickering
If the screen on your device is flickering, there are a few steps you can follow to find out whether the issue is software or hardware related. Flickering is usually caused by a software issue which can be caused by glitches in apps or software bugs.
To best protect your device, make sure to update the software so that it is running the latest operating system and has the latest security updates installed.
If the screen on your device is flickering, the first step is to restart your device. This is often the quickest and easiest way to resolve software issues. Follow the steps below to perform a soft reset on your device.

Safe mode can be used as a diagnostic tool that lets you run your device at the basic interface without any third-party apps. This helps to determine if the issue you are facing is due to an installed app.

If the flickering stops when your device is in Safe Mode, it could mean that the issue is being caused by a bug with one of the apps you have installed. Find out which app is causing the problem and uninstall it. Start by uninstalling the most recent app you downloaded before the problem started. Repeat until the flickering stops. You can always reinstall an app if it wasn't causing the issue.
If the flickering persists even in Safe Mode, it is likely the issue is hardware rather than software related. If this is the case, contact your nearest Samsung Support Centre to book an appointment.
If your screen is still flickering, try adjusting your brightness settings, and disabling the adaptive brightness feature.
If your device only has two buttons, press and hold the volume up and side buttons until the Samsung logo appears.
If your device has a dedicated Bixby button, press and hold the volume up, Bixby, and power buttons until the Samsung logo appears.
If your device has a dedicated home button, press and hold the volume up, power, and home buttons until the Samsung logo appears.
If you have enabled developer options and have adjusted the settings, this may be causing your screen to flicker. Follow the steps below to see if this is the cause of the flickering.
