Despite perceptions, the Retina Display on the iPhone 4 is overall better than that on the Samsung Galaxy S, DisplayMate discovered in a close look at smartphone screens. Apple's screen was undersaturated and too high contrast in photos, but its brightness, deep blacks, high contrast ratio and 960x640 resolution all made it the overall best display of five different models. The Galaxy S' Super AMOLED was better in blacks and contrast but, like many OLEDs, had oversaturated color and was noticeably dimmer.
