There are 3 screen modes on Samsung Galaxy S II ~ Dynamic, Standard and Movie mode. If anyone of them is not your cup of tea, you can try a new present from Voodoo ScreenTune for Samsung Galaxy S2. Voodoo ScreenTune is currently a development application but rest assures that Supercurio who behind of Project Voodoo for Samsung Galaxy S will make a better application for our lovely Samsung Galaxy S2.
Supercurio reverse-engineered all the mDNIe image converter registers so that Voodoo ScreenTune can improve Galaxy S II Super AMOLED+ screen and rendering. Currently, Voodoo ScreenTune is working on Standard present mode only. Do take note on this. The screen looks softer and less colour banding issue. Try it and see it for yourself.
