By the way even my Samsung OLED monitor and tv shifts the entire screen area every view minutes by a tiny amount to further prevent any burn in issues.
As I also already said, all my previous Samsung phones with always on displays had that shifting feature from the very beginning, even the newest Samsungs from this very year shift the screens. Personally I appreciate this burn-in preventing feature very much, on my first Phone (2), I actually disabled the aod because of the missing shift feature.
