Touch ID not working after screen replacement (original Home Button)
Hello, yesterday I changed the display on an iPhone 6, everything was working fine except for Touch ID. As I already repaired many iPhones I know that only the original homebutton will work with touch ID so I used the original button, but everytime I try to register a fingerprint it says "Touch ID failed" (don't know the correct translation as my phone is in german). Pressing the button to get to the homescreen and so on works fine, just touch ID is giving me problems. I did definetly not damage any part of the flex cable or the button.
I already tried performing a factory reset and also restarted with home and power button but still no success, also reattaching and cleaning the ports with isopropanol didn't fix it.
Does someone have an idea what else I could try?
