Started with EXTBlue 09sept, had the phone freeze up a couple times when exiting sleep mode. Flashed a nightly over that, problem persisted. Also had it randomly restart a few times. From there, started over by wiping everything, and flashing a nightly (091710 I think). Still had the problem, found the so-called "6.1" update, wiped again and went with that. I still have the original problems, and now it's also freezing up on the camera screen. Otherwise happy with the performance and such, any suggestions?
