The next innovation in mobile is peeking its head for all to see today after Chinese companies Oppo and Xiaomi both showed off under-screen cameras.

Apple’s notch set the ball rolling as a new way to pack a front-facing camera without compromising on the screen size, but it is already feeling date. The industry has since given us smartphone cameras that pop out, flip up and slide out, while the hole-punch condenses the notch further still, but the next stage is going under the screen for full invisibility.
