So I bought a iPhone 6 Plus with a busted up screen and missing home button, got it pretty cheap. I repair iPhones so I’m always looking to buy broken ones to resale. I installed a new screen and homebutton on the iPhone and new front facing camera. My Touch ID never worked and I didn’t expect it to because I knew it was a after market homebutton. Well like 10 makes minutes ago I installed the new iOS 11 and after the update completed it asked me to set up my Touch ID and I was surprised when it was actually scanning my finger print! And now my Touch ID feature works again even with this aftermarket home button!!! Is this a glitch with the new iOS? Or have they allow d aftermarket homebutton to be able to set up the Touch ID feature?
Tested on an in-store phone we use for parts diagnostics. Didn’t work. You may have just gotten very lucky and had the serial numbers match.
