I've just upgraded my phone so am planning on selling my old S8. But it has screen burn!
I've downloaded the OLED app and had it running overnight but it hasn't made a difference.
Is there anything else you can recommend?
Samsung know some phones can suffer from screen burn and I've come across posts where people have had the display swapped out by Samsung under the two year manufacturing warranty as long as no other damage is present i.e from an accidental bump etc @Rmatt
