I have to say, I love the feature on my phone as it works incredibly fast and reliable. Samsung could be planning on doing away with the fingerprint scanner. According to a tweet out of China, a member of Samsung's staff allegedly said, "We will kill the fingerprint, it's obsolete." The Samsung Galaxy S8 and Galaxy S8+ both have a fingerprint scanner and an iris scanner on board.
However, a recent report said that the iris scanner has been working too slowly and has not been reliable, forcing Sammy to add facial recognition to its new flagship handsets. The latter will supposedly unlock a phone in .01 seconds.
Now, the cycle starts over; before you know it, the iris scanner will have followed in the footsteps of the fingerprint scanner going from rarity to commonplace. If the tweeted quote is legit, Samsung could ditch the fingerprint scanner by the time that the 2018 flagship model is unveiled.
