Nubia Z18S surprised with two color displays

The Chinese manufacturer ZTE, apparently, wants to surprise the users. The future flagship Z18S will come out without a front camera, but with color displays on both sides of the smartphone.
Recently, the problem of the location of the front camera is excruciating almost all manufacturers of mobile devices. In order to save space on the display, someone makes a cutout for it, someone uses special retractable mechanisms, and ZTE went even further and simply abandoned the front camera. That's right, why it is needed, if there is a second color display on the back of the gadget, with which you can do selfie directly to the main camera.
