Phone screen with flickering lines after an update

[RickyRocky]

I have a samsung s20 ultra and it is working great. After an update, something happened and my phone started having these weird horizonta flickering lines that is not noticeable but very distracting on some white pictures or any other colors. Does anyone know any fix for this?

I tried it many times but the issue still persist. I found the issue however. I drained my phone to 0% and while its drained, I cleaned my phone and it worked. The lines are gone. I had the issue before but it went away for unknown reasons. It happened again after putting my phone in my pocket so I deduced that lint is the cause of the problem.
