One thing holding me back from upgrading is how fast my 8's fingerprint sensor is. Sometimes it's too fast for me to use Apple Pay, as it unlocks faster than I can double click. It is so fast, it feels like I'm simply clicking the button to unlock, instead of clicking to wake, read my fingerprint, then unlock.
