Your thumb la..Mine works fine on ip6s+...Only bluetooth function everyone talking about buggy...Battery seems to drain alot for me i feel..
I find waking up the phone and unlocking it via finger print is not as responsive as the 10.3.3 on my ip6s+. Sometime I need to make sure my thumb is still placed on the home button before the unlock happens.
I got feeling Apple has tons of bugs to fix for iOS11.
