Nubia X hands-on: Two displays, two fingerprint scanners, almost no bezels5
Taking a page from the same book that treated us to the Vivo NEX, the Nubia X is a device that would most likely turn heads due to its pretty obvious, telltale design highlights - the dual-screen setup that has allowed the complete forgoing of a selfie camera at the front as well as the nearly bezel-less display that spans edge to edge and doesn't boast a notch of any sort. That's not a new concept, but there's definitely more going on with the Nubia X.
For example, instead of utilizing a button to switch between the front LCD display and the rear AMOLED one, the Nubia X utilizes a nifty squeeze gesture that's essentially similar to the one the Pixels employ. You squeeze the frame, and voila, the other display will light up and become active. This is certainly a boon to multitasking as you delegate the essential feature of switching between the two displays to an intuitive gesture.
Aside from being a fully-functional display, the rear one also functions as action buttons while playing games, a gaming-oriented feature that is similar to the Nubia Red Magic Mars and the Vivo NEX.
