S20 ultra sceen issue

[qwerty2]

I recently started noticing fine grey horizontal lines that move upwards, like old 80s TVs.

Resolution is still perfect, and these lines are only visible on white background and on whatever app i am using.

Sometimes they are barely noticeable. They are minimal and very fine.

I have no available software updates, i tried power restart, increased and decreased refresh rate. Nothing seems to work.

Any suggestions?

This is not a software issue, this is related to hardware, which is the screen in your case, so you should visit a qualified station to check your screen if it could be fixed or to be changed if needed.
