The Oxygen OS 5.0 update brings the OnePlus 5T’s new face unlock feature to the OnePlus 3T. The company had always said that the feature was a software-based implementation, so the news isn’t really surprising. In fact, Face Unlock isn’t even a feature OnePlus developed. Instead, it’s Google’s “Trusted Face” feature, that has been part of Android for years now.
The Trusted Face feature allows users to bypass the lockscreen when they’re in particular situations, which include Trusted Locations, Trusted Devices and more.
The Trusted Face feature was originally added in Android 4.4 KitKat, though it wasn’t known by this name at the time. Google started calling the feature Trusted Face since Android Lollipop, and it has always been part of Android’s Smart Lock implementation. This allows users to bypass the lockscreen when they’re in particular situations, which include Trusted Locations, Trusted Devices and more.
Using the feature on the OnePlus 3T is the same as using it on any other Android phone. You go to Settings, find Security and Fingerprint and choose the Smart Lock option. Although, OnePlus had brought the feature outside Smart Lock on the OnePlus 5T.
It’s also worth noting that many Android OEMs seem to have removed the Trusted Face feature from their devices. That’s likely because the feature isn’t completely dependable, which is something OnePlus had also warned users about at the launch of the OnePlus 5T.
