Hi my iPhone 6s Touch ID seems to have gotten worse When I first got it it was blisteringly fast but since updating to 9.1 it now takes 3 seconds to unlock. I've tried ..... Restoring Restoring with no back up and starting fresh Adding my print 5 times If I reboot it works perfect but later on it'll **** the bed again. Anyone have the same prob? Anything else I can try before I take it to Apple. Thanks.
