I had set my phone up as an erased “new iPhone” prior to the repair. After completing this repair my Touch ID appeared to be working normally and I added 4 fingerprint profiles. After a few hours Touch ID failed and the fingerprint profiles disappeared. Attempting to add them again would not work. After performing a “Hard Reset” the previously entered fingerprints returned and functionallity has been completely normal for a couple of days now. I will repost if another failure occurs.
