Iris Sensor Not Responding

[Dr Jones]

Anybody else having issues with their iris sensor just randomly not working? It's been happening almost daily. A phone reboot corrects the issue... but that is really annoying. This isn't an issue of "iris not recognized"... this is an actual error displayed that says "iris sensor not responding. try again later".

I never received that message, but my first S8 (returned to Best Buy after one week when Samsung BOGO came out) wouldn't unlock with iris at all until I disabled facial recognition - which never worked anyway nor does it work on my current S8.
