Oppo's camera hides on the front of the screen under the display. Oppo

Chinese phone maker Oppo published new photos on Wednesday of a prototype phone that hides the front-facing selfie camera completely inside the screen. The prototype was on display at the MWC tech conference in Shanghai. Right now, since cameras aren't yet able to sit beneath a screen, manufacturers like Apple need to create a notch at the top of the screen that allows the camera and other sensors to sit on the front of the device while still allowing as much screen as possible.

Even with the camera launched, it hides below the screen in the black border above, where the pixels have been turned off. Oppo

Samsung has helped to alleviate this with its new Infinity-O displays, which leave just a tiny hole for the camera lens. And OnePlus, which is owned by the same company as Oppo, has worked to create smartphones where the whole front is one big display by including a mechanical camera that hides inside the phone and pops up when you need it.
