Smartisan U1 is designed to be appropriate rather than only affordable. Like many everyday objects, it’s humble yet elegant, without any compromise on design quality. It has an iconic front face inherited from Smartisan T1, whose proximity and ambient light sensors are integrated with ear speaker into one single pill shape. The changeable back covers for U1 come in a range of rich colors and the classic line design makes the phone interact with hands tactilely. The perfectly symmetrical geometry makes it suitable for both right- and left-handed user. It runs simple and easy-to-use with Smartisan OS 2.0.
