Another Touch ID not working question
I bought an iPhone 7 with a screen that had a single crack in it. Tested it and everything worked fine including touch id. Had an extra screen laying around that may have been water damaged and thought I would test it just to see if it worked, which it didn’t.
When I connected the old cracked one back touch id wouldn’t work anymore.
First it reacted like I was double tapping. Inspected every cable and pin, but can’t find any breaks. I also did an DFU reinstall, but touch id still won’t work.
When I try to add a fingerprint it doesn’t register anything.
The home button works fine besides touch id.
What could the fault be?, could the screen I test fitted have caused damage?.
When I removed the old screen I didn’t touch home button flex cable, but could damage to the other three flex cables that connects to the logic board result in symptoms like the ones I have?
