My fingerprint scan issue persisted. Angry, today knocked off came home, try without screen protector (spigen), re-scan and use, looks okay the first 15 mins, left the phone alone for 30+ mins and came back, finger print fails again. Tried last resort, factory reset with no screen protector, scan works fine and all, then left for 30mins alone, came back and prints not working well again. Feels like a bug more than sensor problem, but I'm not sure. Gonna open ticket with amazon to see if I can still return it.. I have so much accessories bought for it, not sure if I should give it another try.
