Although smartphones with 2K screens are nothing new, the resolution is only just now starting to become the de facto standard for flagship devices. In order to distinguish itself in a crowded market, however, ZTE will reportedly be the first company to equip a smartphone with a 4K display. According to reports, the company’s upcoming Star 3 flagship will come with a 5.5-inch 2160×3840 display, which would offer an insane 806 pixels-per-inch.
