Once you've had the phone for a few weeks, reprogram your fingerprints. I've done this and have now noticed major improvement in its accuracy. I had a theory that, after owning the phone for a while, you develop habits on how you hold the phone. Once those habits are developed, how you place your finger will likely have more consistency. This seems to be accurate with the improvements I have seen post reprogramming. So what are you waiting for.....go do it.
