so if you have dry hands fingerprint won't work. Mine were dry so came home and moisturized and worked instantly

a few things, 1 do you have a screen protector ?. if yes go to touch sensitivity and make sure it's on. 2 erase your finger print and try another finger

Yep, that will definitely do it. My hands get extremely dry during the winter. Applying some hand lotion or wetting your finger slightly usually works. 

When medical professionals do an ultrasound scan they typically apply gel to the area. Same concept with in screen fingerprint scanners. If your finger is too dry, the scanner can't properly read it.

I have two fingers registered (thumb, index) because sometimes the thumb doesn't always work

I also use Face Recognition ... fairly reliable
