While local competitors like Vivo, Oppo, Xiaomi and Honor have been trying various sliding mechanisms to achieve all-screen, notch-free smartphone designs, Nubia decided to take the easy approach: Getting rid of the front cameras and forcing you to use the rear cameras for selfies. This is why the freshly-announced Nubia X is a dual-screen flagship smartphone, with its 6.26-inch FHD+ LCD covering almost the entire front side, and the back featuring a smaller 5.1-inch 1,520 x 720 OLED panel to go with the dual cameras. A bit like Yota’s implementation, except it’s OLED instead of E Ink on the back; plus no front cameras, of course.
