I came across one also where if I tried to add a finger print after installation it would not let me, I could delete it just fine, but after I deleted it would not let me add another, only if I completely wiped and reinstalled was I able to use the finger print againThere is a very big problem in this rom. After adding my fingerprint. Whenever I lock my screen or press the power power button. And when I agai. Press the power button the screen just stays blank. I mean I still can feel the vibration of my pin. But the screen stays black. And if I press the pin number just randomly then the screen just wakes up with only option to unlock my phone through pin. So this is the reason I am only using pin. Tomorrow I will be providing the logcat.
