From what we heard it seems like Galaxy S8’s iris scanner will not turn as great as it could, with Samsung saying that it works ”too slow”. The company has decided, perhaps to combat the low performance of iris scanner, to also implement a facial recognition system into their upcoming flagship. Or maybe it is Samsung’s reaction to iPhone 8 allegedly coming out with the facial recognition. Whatever the reason, it is unknown whether the face scanner will take iris’ place or work alongside it.
