OnePlus 6T Tips: How Does Face Unlock work? Is That Safety?

Face recognition technology is designed to enable a system to correctly identify the face of a person. The technology uses a set of algorithms which compares the various facial features, their size, and distance from one another to make an intelligent decision on the identity of such a face. Such scanned features are compared to those stored in the database and thus aid in making a correct match.

Facial recognition is widely applied in various systems. One area where facial recognition technology has received a considerable application is in the Face Unlock systems on Smartphones.

How does Face Unlock Work?

The Face Unlock works by comparing the facial details captured during the unlock session with those which were captured during the Face unlock set up.


The most intuitive of these Face recognition technologies is the Apple FaceID. The face recognition system does not only capture the size, shape and the proportional distance of various facial features but goes to an extent of capturing the groves and dents on your face. It is thus a 3-D technology implying that such a system cannot be tricked by the use of a person’s photo.

OnePlus has incorporated facial technology in their OnePlus 6T release. Though this technology is not as effective as that of Apple’s FaceID, it has a certain level of reliability. The technology captures over 100 different facial details which it uses to compare and differentiate the right face from the rest.



The face scan is usually done via the front camera. If the details of the captured face match those which are in the database, the smartphone unlocks. In case there are deviations between the facial details captured and those stored in the database, the smartphone does not unlock. For security purposes, the smartphone is set to prompt another form of unlocking the phone after 5 Face Unlock attempts.
