Recently my phone's power button fingerprint scanner has been failing a lot lately. Normally it doesn't work the first few times, every once in a while. I'm not sure why but this week especially I feel the scanner hasn't worked much at all. It still will sometimes but there are dozens of times a day, now, where I am required to enter my pin. Is anyone else having this issue? Is this related to the latest updates or some kind of forced malfunction to push people towards upgrading to the newest phones?
What @Oxford said, as well as did you do a diagnostic on the fingerprint scanner? The fingerprint scanner on the side button was always the worst possible idea; my guess is it's failing from fatigue and old age. While planned obsolescence is definitely a thing, I do not think Samsung is deliberately targeting your device so you will be forced to upgrade.
