Ok, I feel seen. I had trouble with TouchID on the 5S, upgraded to a 6S, and a 7 and continued to have trouble. It never reliably worked for me. I partially blamed it on oily hands, but my fingertips are fairly scarred as well. As soon as FaceID was revealed, I jumped ship to the X series phones and can't imagine going back. It's crazy how much more reliable FaceID is for me than TouchID ever was.
