I bought my first smartphone with AMOLED display and I noticed something weird compared with all my LCD screens. Every time there is gradient dark/grey color (wallpapers, apps backgrounds, ...) the gradient is always "broken" and become just a big and ugly full black area. I checked on all my previous smartphones with LCD and I have never this issue.
See here my pictures, in the "Battery HD" app, all the top display is only a big black box, is it normal? Can someone install this app a tells if it's the same issue on AMOLED please?
