I have the phone for a few mouths and all was good, but for a few days the finger print is no longer working. The light of the fingerprint gets light for a second then get off and on while I have the finger on the scanner. I clean the screen, restart the phone, turning it on and off. Also the Add a fingerprint is greedy out and if I delete the one that I have it remain grayed out until I restart the phone. I also notice some glitches on the screen but there are no repro steps.
