Under-Display Touch ID
A few years ago, Touch ID disappeared from the iPhone for good. Unless you have an iPhone SE, you’re probably unlocking your iPhone with Face ID, which does work pretty well.
However, the problem is that Samsung phones have been able to use both facial recognition and fingerprint sensors for years now.
Samsung solved this by adding the fingerprint sensor below the screen, which Apple should copy right away.
We’ve seen several rounds of rumors over the years that Apple was developing an under-display Touch ID feature. However, more recently, we’ve heard the under-display Touch ID project is dead, so it doesn’t seem likely to be available anytime soon. Apple seems to consider Face ID the way forward, and rumor has it that even the next iPhone SE will make the switch from a fingerprint sensor to facial recognition.
