Fingerprint sensor problems

[woody1]

The fingerprint sensor has been working for me just fine ever since I got my M3, but today it suddenly became unreliable. I have to try several times to get it to work and I have to move my finger around on the sensor before it will detect. I decided to delete and re-register one of my fingerprints. When I try to register now, the registration screen will register 4%, then it won't go any further. After a few tries, it says "Unable to register, please try another finger, etc."

My tab is a WTV-W09 on Android 7, EMUI 5 rooted with SuperSU. I haven't done any software upgrades, so I don't know what would cause the change. Does anybody know what the issue might be?

I've found that both my mediapad and my LG G6 are struggling to get a good fingerprint read in the past few weeks. It seems to be related to the cold dry weather. Even when I'm indoors, my fingertips are very rough, dry, and often chilled, compared to more normal weather.

That could be the problem. I'll experiment some more and see.
