^ Gave it a go right now on the phone while I recorded the experience (already hid the notch yeah lol), my first experience with this kind of under the display fingerprint. I can't compare with the Mate RS but this seems pretty usable and fast enough.
Doesn't even begin to compare to the other scanners on the P20 or Mate 10 though. This one struggles upside down while on surface level scanners I could basically just not give a crap and put the finger anyway I wanted and tap the scanner instead of leaving the finger there. Well I'll just use the face unlock anyway, as on the P20.
I'm curious about the battery of this boy. I'll be using it at 1440p to test it out compared to the Mate 10 Pro.
