My iPhone 5s was purchased Nov 2013 and I setup Touch ID at that time and it has been functioning without any problem until Mon 15 Sep when I was running iOS 7.1.2 - I had not made any changes to the iPhone but the functionality just stopped working
The iPhone unlock and the iTunes & App Store unlock were off but on each attempt to activate these I receive a Failed message - unable to complete Touch ID setup
I have tried a hard reset but this did not resolve the issue
Today I successfully upgraded to iOS 8 and I thought that this would restore the functionality of Touch ID but unfortunately that is not the case - same error message when trying to activate the iPhone lock
The passcode is active and continues to function and has not been changed since originally set Nov 2013
Can anyone assist in re-activating the Touch ID functionality ?
