We’ve already known about the G8 ThinQ for some months now. And a few weeks back, LG made the whole camera rig official, announcing that the handset would be getting a ToF image sensor on its front-facing camera, bring, among other things, advanced face unlock technology.

The company did manage to save a few tricks for the product announcement, including a strange little biometric addition. LG says the phone’s Hand ID tech is the first to use “advanced palm vein authentication” — which could well be accurate. Certainly it’s not a mainstream feature yet.
