Samsung Galaxy S II Super AMOLED Plus display is great. But the colour like green and red are over saturated from my point of view. Voodoo ScreenTune helps to improve the colour banding issue. But it does not solve the over saturated issue. Therefore, Chainfire3D Pro’s night mode comes to rescue. You can turn red, green and blue colour levels with it.
