To maximize the total screen real estate on a smartphone, manufacturers have taken different approaches. From notches to sliding cameras, this is what is commonly seen on devices. In order to achieve an edge-to-edge display, ZTE’s Nubia brand has come with an interesting new solution. Its new Nubia X doesn’t have a selfie shooter, thereby dispelling the need for a notch. Thanks to a secondary display on the back, the phone’s rear cameras could be used for taking a selfie. This is certainly a unique way to snap images, and we want to discuss the other hardware details with you too.

The front display of the Nubia X is 6.26 inches with a resolution of 2,280 x 1,080 pixels and an aspect ratio of 19:9. The phone does have really slim top and bottom bezels, and it has managed to achieve a screen-to-body ratio of 93.6 percent without the use of a sliding camera mechanism.
