Touch id no longer recognizes my thumbprint when case is on phone
My phone no longer recognizes my thumb print when the Spigen protective case is on the phone. When I remove the case, the touch id works. This has been going on for a few months but prior to that, the phone was working fine ( a little over a year old). I took the phone to an Apple Store and the phone passed all of the diagnostic testing. They had no explanation as to why this feature no longer works consistantly with the protective case on. I have all the latest updates and re-calibrated my fingerprint multiple times.
