RuBi0_ , via OnePlus 7T Pro , Oct 19, 2019 : While watching a Video I noticed some strange flickering on screen. The lines are about 10-20 pixels thick and only appear for a fraction of a second and after that they disappear again. Restarting the phone didn't help an I tried turning off 90hz and switching to 60hz but that didn't help. Does anybody also have that problem? Is there a way to fix it?
