Hi,
My Note 20 ultra has some Display problems.
When my phone is on a lower brightness and Adaptive(120Hz) refresh rate setting on a grey background, I can see all sorts of funky horizontal lines across it.
(except gallery - i think the refresh rate reduce to 60hz in gallery automatically so in gallery you can't see the problem).
I see them big time on settings screens or Apps where there is a gradient of gray.
see the attached Picture. Two pics with 120Hz(Adaptive) Display Refresh Rate and others with 60hz!
Note: the problem seems to be more than real in these pictures because of camera, with eyes you can't see such this bad but Noticeable.

Is this something wrong with the phone? Or is that normal??120hz120hz

I am having the same problem. I did notice while in youtube that both of the horizontal lines, which turn virtical in portrait mode, expand and contract when you switch between original video to "fit the whole screen". Any news on what solved yours? Was it a faulty screen?

All note 20 ultras has this problem and even replacement can't solve the problem.

Bad battery, hot phone, Bad display, low score camera. They just improve the price of the phone!

No, there is no any solution.

Even replacing the phone can't solve the problem. I'm a Notes fan, but if one day apple produce any Note like phone i will buy it...
