The Samsung Galaxy S4 has Full HD Super AMOLED display. The product's 5-inch screen has 441ppi and utilizes Corning's new Gorilla Glass 3.
The new feature, Samsung Smart Pause, enables users to control the screen by where they look. When the user is watching a video, the video pauses when the user looks away then it starts right up again when the user turns back. In addition, Samsung Smart Scroll allows users to scroll the browser or emails up and down without touching the screen, Samsung said. The feature allows the smartphone to recognize the user's face when the user is looking at the screen and detects the movement of the user's wrist to scroll the pages up or down accordingly.
