How does the S21 face unlock work compared to the Pixel 4XL? As far as I can tell, it only has the one camera on the front. I read something about iris scanning on the S20. Is that part of it on the S21?
Also, does anyone know what making it faster does? I noticed that is a setting. I mean, I assume it makes it faster but how?
(simply can’t find this on the web, maybe I am not searching right)
