My phone froze up and was unable to get it to respond to any input and I had to hard reset it. After this it would not allow finger print authentication at all wouldn't even vibrate like there was an error. I went in and noticed that no fingers were registered, I used to have my right and left index fingers registered. I tried to add them back but it said "Please try to set the different finger". So I went ahead and registered another finger (right middle) once this finger was registered, and is the only one on the screen I was able to unlock with my right middle, and left and right index. It still shows that only my right middle finger is registered. This is kind of concerning that 1) some how the original finger prints don't show up. 2) There are hidden finger prints that will unlock the phone. This is with a TA-1045 with Build 00WW_3_260_SP01.
