No, not from the user menu. He was likely in the service menu, which I highly discourage people from going into. (There are plenty of posts of those who did and wish they didn't).
That's not a screen burn protection (the colors). The best way is to use the scrolling black>grey>white feature for keeping the panel uniform.
I was wondering how i can change the pattern that i see when i select the screen burn protection option. so far i can only see the white and black pattern. But when a samsung repairman was here fixing my screen he somehow put a bunch of other patters like green and black checker pattern. is there anyway i can do this?
