Good news for OnePlus and OnePlus 3T users, the latest update will not only bring Android Oreo onto your device but also add the face unlock feature as seen on the OnePlus 5T handset. This face unlock on the OnePlus 3 and the 3T should work as fast and as accurately as seen on the 5T.
If you have already updated to the latest Oxygen OS then there is face unlock feature on your OnePlus 3 / OnePlus 3T handset. All you need to do is go to settings, tap security and finger print and then tap smart lock and then trusted face.
You will need to register your face and once done, you will be able to unlock your phone with face unlock. This feature works great on the OnePlus 5T handset, I guess you will get the same performance on the OP3 / OP3T handset.
The OnePlus 5 handset will also get this feature. If you are using a OnePlus 3 or a OnePlus 3T device and have updated to the latest Oxygen OS, and if you have enabled and using the Face Unlock let us know how it is performing.
