Fingerprint sensor repair
Hello
I have an iPhone 5s 16GB which is out of warranty now. I am using iOS 8.4 on it.
My fingerprint sensor scratched or rather has a small crack at the base of the circular home button. The button works fine and has not lost responsiveness but the finger print does not work anymore.
I know that the crack is the reason why it won't work and I want to fix that issue by other fixing the home button. From what I have read online so far, it seems that I am doomed with this phone and it won't ever read finger prints again. However, my conversation with apple over their toll free number has them telling me to send in the phone for repairs and they will be able to fix that and my finger print scanner will work again. Is that true? Because my understanding is that each home button is uniquely paired with the phone and changing it won't ever get the finger print functionality back.
Please respond as to whether I should send in my phone for repairs to Apple.
iPhone 5s, iOS 8.4
