Can't register finger prints

Oh I see... Won't even recognize when you try to register them. Stumped on that one. Maybe try settings>apps>fingerprint>storage>clear cache/data>reboot phone and try again?
 
If your fingers are dry it will not register the finger prints. I've been having that problem for about a week. I wet my fingertip with water and then dry it off and it works.
 
Mine just don't register period, it's just the way my skin is, it never worked on any other phones I have ever had!!!
I am just using the Iris recognition method, it works without fail.

Ditto for me. Fingerprint recognition on any phone over the years is a total fail for me. I think it's my terminally dry skin.

Iris recognition is awesome.
