Nubia X

The Nubia X is an Android smartphone which was launched on 31 October 2018. Given the tendency in the late 2010s toward bezelless displays, instead of trimming the display with a notch or hole for housing a front camera, it opts to use two screens (on both sides of the phone). Selfies and videocalls are made with the main camera and the rear display as viewfinder.[2]
