Face Unlock feature for one plus 5

The OnePlus 5T's other party trick (besides the tall screen) is Face Unlock a quick glimpse at your phone is all it takes to sign in. But is it really worth buying just so you don't have to use a fingerprint reader?
"Due to popular demand, Face Unlock is coming for the OnePlus 5," tweeted out OnePlus chief Carl Pei on Christmas Eve. "Thanks for the feedback, and merry Christmas!"

Pei didn't dive into any details so we'll have to wait for more information to know exactly how this is going to work, but presumably a software update for the OnePlus 5 will be enough to enable the forward-facing camera to recognize faces and let you past your phone's lock screen.

The wider access is possible since Face Unlock is strictly a software feature. It's not as secure as Apple's Face ID (which uses depth mapping and projection to verify that it's you), but it's faster and more flexible. If there's a gripe, it's that there's no known plans to bring Face Unlock to older phones like the 3 or 3T. You won't feel burned if you just bought a OnePlus handset several months ago, but you might be out of luck if it's significantly older than that.
