The fingerprint scanner on my SM T720 has suddenly become very unreliable. This is on a stock, unrooted device. Software is up-to-date. I've tried rebooting, reregistering fingerprints, etc. Does anybody know a way to fix this?

The problem was fixed when I cleared the system cache on my tablet. Just in case anybody else runs into this problem.
