iPhone 7 touch ID fail after battery change.
I changed the battery in my iPhone 7 with an IFIXIT kit yesterday. The repair went well except that the touch ID doesn’t register fingerprints anymore. The home button functions normally otherwise. I’ve removed and attached the screen several times now and can’t see any damage to the ribbon cables. I also disconnected and reconnected the battery.
Are there any suggestions for fixing the touch ID? I saw one similar question where the person bought a new screen and was successful. Is that the first or main solution, or are there any tests or other things to try?
Thank you for any suggestions.
