To fulfill our promises regardingdisplay in full screen, OnePlus has implemented a front-facing pop-up camera in the 7 Pro.

Nexus One boasted a rollerball,located below the display, which could be used instead of a sensor to, for example, scroll through the menu on the phone. (At one time, I myself used the HTC Hero for some time, which also had a similar feature with a roller under the screen - ed.).
