The Chinese corporation ZTE filed a patent application at WIPO (World Intellectual Property Organization) last year. But the patent was received only on April 5 of this year. It is designed for 2 devices.

One is frameless, and there is not a single connector on it. There are no buttons on the front panel. There is only one button, and it is located on the side, on the right side of the device. The fingerprint sensor is supposedly located under the display glass. In the upper left corner of the rear panel is the built-in main video camera.
The second device, judging by the images presented in the patent, is aimed at covering the budget segment of the market. The fingerprint sensor is located on the back. The main camera is dual. At the top of the display, a small slot is visible under which the earpiece is located. A pair of connectors are visible on the sides of the case. One for a wired charger, the second for connecting headphones. There is also a “rocker” to adjust the volume and a button to turn on the smartphone.
