On the resource Slashleaks there were renderings of smartphone Nubia – it is possible, it is model Z18. The device, like the vast majority of others, will receive a frameless display with an aspect ratio of 18: 9. The smartphone is allocated to others – it has a second screen located on the back panel.
The renderers are not particularly informative: they are simply displayed on the rear display. What else the screen will be used for is not yet clear. The matrix used is also not specified. In the Russian YotaPhone, for example, the second display for saving the charge was performed using E-Ink technology, as in most e-books.
At the bottom of the smartphone there is a 3.5 mm jack and a USB-C output. The fingerprint reader is likely to be located on the faces – it is possible that the sensor will be two at a time.
