This question is for those that ARE using one, I'm not asking if you use this or the fingerprint or the iris scanner alone. So if you use any of these two, which one?
Face unlock is a lot faster almost immediate during the day or on a well lit room and works on the desk, at an angle, up to 3 feet away.
Intelligent scan uses both face and iris but the face one seems to be inferior as works slower and it won't unlock on the desk, a pop up message comes up saying to put the phone straight and closer to my face and doesn't unlock until I put it straight and at around 1 ft of my face (bummer) BUT it has the advantage that it will still work at night or in the dark because of the iris scanner (but is also slow so I just use fingerprint most of the time in the dark)
