One of the problems with facial recognition systems like Face ID on the iPhone is that you need to more or less stare directly at the phone for it to be unlocked. It is a security feature because it wants to make sure that it is you unlocking it, not someone holding it to your face, although the downside is that it isn’t as easy to unlock compared to using a fingerprint.
However, the good news is that with the iPhone 11, Apple is expected to make some changes to Face ID where it will now support multi-angles. What this means is that the sensors will be able to detect the user’s face even if the phone isn’t necessarily held straight up, and where it could potentially even allow the phone to be unlocked while it lies flat on the table.
This isn’t the first time we’ve heard reports that the iPhone 11 could feature an enhanced version of Face ID. Analyst Ming-Chi Kuo had previously reported that Face ID on the iPhone 11 could have a more powerful flood illuminator that could be used to overcome interference from other infrared sources.
That being said, it seems that despite these improvements, there is a chance that Apple could still bring Touch ID back to the iPhones. There have been some reports that suggest that the 2021 iPhones could feature both Face ID and an under-display Touch ID.
