Facing the same problem... Whenever i open youtube their is some redish tone on the screen and if i switch to any other app their is some blackish tone on that app which disappears after few second.
I m facing the same problem. This happens to me all the time when my phone's brightness lvl is 0. I have my adaptive brightness off. When I locked the phone and unlocked it, the brightness is somewhat high even though the brightness is still on 0%.
