Optical in-display fingerprint sensors use a camera module to map the grooves and ridges of your finger, and it’s likely OPPO is scaling up the tech to add a higher-res module underneath the screen. The phone in question is clad in a protective case that’s designed to hide any distinguishing features, but it is possible OPPO will launch a phone with an in-display camera module sometime this year.
Not to be left behind, Xiaomi also showed off its implementation of the tech in a teaser video. It’s likely we’ll see an in-display camera debut on the Mi Mix 4, which is due for an official unveil later in the year.
