samsung team plz work on "3D face recognition model" to make face unlock even more secure, better and faster it will improve face unlock of other samsung mobiles with samsung note 20 ultra.
Great suggestion, it would feel more secure and accurate if Samsung does this👍🏻 But Face Unlock is always going to be less secure than Iris. I really miss the Iris scanner from my old Note 8 (especially now in the 'mask' era, we need it even more).
I think they had to remove that because of design aspect (single pinhole for camera on the front). Otherwise it would have been the same design with multiple sensors at the front on thick bezel (which could have looked outdated in 2020).
Technically speaking, I don't think there is a way to fit Front Camera + Iris Scanner in one pinhole. A dedicated sensor is required for Iris.
