I have had his same problem where it would work maybe 1-2 tried out of every 10i have had my 6s plus since launch day and maybe two or three times the Touch ID doesn't recognize. It doesn't even say to try again. I have to swipe and then press my finger on Touch ID. I'm assuming it's software bug since it works 98% of time but anyone have this hapoen
Since I have purchased an otterbox and the little fingerprint sensors thing built into there cases has actually improved it a ton!!
