Jumping from a 4.8-inch display to an almost Note-like 5-inch Full HD Super AMOLED display, the S4 promises 441 ppi which should mean a massive jump in terms of clarity for what is already one of the brightest and most vibrant smartphone displays on the market. The new Adapt sound and Adapt display tech will also change the screen and sound settings to suit whether you are watching a video or reading an article on the web.
