Happened once. Flickering screen 

[TeamGalaxyRene]

Hello Beemoon22,

We are sorry to hear about your experience with your beloved Samsung Galaxy Note 20 Ultra having issues with the flickering screen. I feel and understand why you are worried for a device that you've take care so much. If my device is facing similar experience, I will be bothered too.  

Before you try out the below recommendations as to your solution, be sure to check if your device's software are updated with the latest version. Please check how to update your mobile device's software in the following order. 

Step 1. Go to Settings > Software update.

Step 2. Tap on Download and install. 

Step 3. Follow the on-screen instructions.

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.

Method 1. Check your device for damage.

If there is damage to your screen, this could be causing your screen to flicker. You can visit the nearest Authorized Samsung Service Center in your area. Rest assured that your device will undergo an assessment to pinpoint the root cause of the issue. Our Samsung engineers and technicians will guide you and offer solutions to restore it.

Method 2. Restart your device.

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.

Method 3. Check in Safe Mode.

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

Method 4. Manager your brightness.

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

1. Go to Settings >  Display. 

2. Tap the switch to deactivate 'Adaptive brightness'.

3. If you have noticed the flickering with low brightness, slide the bar to increase the display brightness.

My note20 is already dead. Happened again and upon restart same thing.

That is weird. It happened to me as well the same day you posted this issue 6/22. My phone got fixed when it turned off due to a drained battery, however still experiencing some side effects of flickering screen and my resolution is to power off my device, however i noticed something that once the screen start to flicker and i try to open netflix and play a video the issue would stop and the phone would function as normal. Just checking if this is somehow related to a software issue?

[Beemoon22]

I did a factory reset when it stopped flickering and after it seem to work normally again but i decided not to use it for now. Will let it rest 😅

I hope the galaxy team will be able to develop a software update to solve the green line/ flickering screen issue
