Iphone 6s Plus Touch ID not working after IOS11
Hi guys,
So having an issue with my iphone that the touch ID is not working. I updated to IOS 11 from IOS 10 and a week later I wanted to reboot my iphone since it hasn't been shut down for almost 6 months. After reboot first thing I saw on the screen it was "Unable to activate Touch ID on this iphone". And I tried to go to TouchID & Passcode to activate it I get "Unable to complete Touch ID setup. Please go back and try again". And I can see "Add a fingerprint..." this option is disactivated. My phone has never been damaged the screen is in good shape and its never been replaced. I need help ASAP.
iPhone 6s Plus, iOS 11.0.3
