Touch id scanner dead after update 7.1. Tried remove fingerprints but cannot add new fingerprint because the touch id scanner DEAD. Tried rebooting the device and touch id scanner still doesn't work. For somehow the scanner works when the iphone is charging even it works slower than before the ios 7.1 update. APPLE PLEASE FIX THIS!!!
