iPhone 5s, iOS 8.2, Fingerprint sensor is suddenly not working. I have the iPhone 5s with iOS 8.2, and the fingerprint sensor suddenly stopped working. It worked fine earlier today and before.I had the fingerprint feature on since i got the phone when it came out with no issues until now. I deleted all of the fingerprints and tried to set them up again, but now it keeps saying that my fingerprint are unreadable. But a few times it makes it through the set up, but they will not work unlocking the phone. I tried resetting it a few times with no avail. Hoping someone here could help.
The clip that holds the ribbon cable plug in 
Place on the home button has come lose allowing the plug to Free float in the socket. 
Open the phone being carful not to open 
It too far and snap the clip back in place,
And never subject your phone to excessive 
Vibration like a bike Handlebar cradle. 
Close the phone and you are good to go.
