The phone consists of a much larger 5.5-inch AMOLED touch display providing Full HD 1080 x 1920 pixels screen resolution and 401ppi pixel density. The 10-point multitouch screen is made of top-of-the-line Corning Gorilla Glass 5 for best-in-class protection. The screen employs ASUS ZenUI 4.0 user interface which is the 2017-released version of the UI and improves navigation experience.
