Looking at the schematic image from the patent application, we can say that the design of the novelty by and large does not differ from the line Mate. All the same rounded edges on the edges of the frameless display. Judging by the application, the manufacturer is still thinking about the placement of camera modules. The small display can be located at the top of the module, at the bottom or between two pairs of lenses.
Most likely, the mini-display will display the time and other notifications.
