While most folding displays are designed to stay in one of two positions the Z Flip has a three-stop hinge which lets you use the phone in a revolutionary way I like to call half opened. With this, you can fold the Z Flip part-way and use it in effectively two halves.
Unlike the Motorola Razr, and other folding phones of its kind, the Galaxy Z Flip also doesn’t have a big screen on the lid so you can use it while your phone is closed. Instead, the Z Flip has a tiny 1.1″ display next to the camera that you can use to check out your notifications, see who’s calling and all that.
