We have long known that Google is in the process of being destroyed proper face recognition to Android to compete better Apple's Face ID. With that new Android Q beta 4, we finally see system settings related to facial recognition.
Years ago, Google included face recognition as a way to get your Android smartphones (the Galaxy Nexus, for example, had the technology). When Android Lollipop rolled out, Google moved the face unlock option to the Smart Lock section of Android. This allowed users to unlock their devices with their faces, but they still need a fingerprint or password to do things like approval Google Pay transactions.
Theoretically, face recognition in Android Q will work just like a fingerprint sensor. This means you can use your face to do things like approving app purchases, approving Google Pay transactions, and of course unlocking your phone.
Unfortunately, face recognition doesn't work in the latest beta of Android Q yet. However, you can see options related to technology within settings by doing a "face" search. This makes it very likely that this new technology rolls out. with the stable version of Android Q.
With face recognition that will probably start with Android Q, more OEMs will need to include the correct sensors to enable secure face recognition, such as time-of-flight sensors. Huawei and LG have sent their latest flagship with these sensors, but many other OEMs – including Google – do.
