[Oreliko]

hello, I bought my tab s6 before a week. The tablets screen change his color randomly to a very warm and sharp colors. And when I open the lock screen, the color become normal again. Please help me, thanks

@Oreliko: That's strange. Have you tried changing your lock screen wallpaper, to see if you notice a difference? Alternatively, if you go to Settings > Display > Adaptive Brightness, and switch this feature off, does this help at all?
