[Galaxy Note 3 Android Development] javarithms:
I have a T-Mobile Note 3 and have the reboot issue too. According to last_kmsg it's caused by the modem crashing. I don't see an option to attach the last_kmsg file so I've pasted the error section only in case it helps. Sorry in advance if this is not the kosher way of doing it. Any help would be greatly appreciated. Thanks.
