I will say I have been playing with an iPhone 6+ and the Touch ID on that has worked like ... 99.9% of the time. Pretty nice. I just wish on the Note 4 I didn't have to swipe on the button... That would help with the failure rate I bet.
It is all about the set up.
When doing the initial 10 swipe set up use any and all angles.
Doing that I have had no trouble at all.
Another option is to set up multiple prints
It set up easy enough but man I couldn't access my phone! So I turned it off![]()
