Last night it started buzzing and will not stop! I have restarted many times. It did stop for about 4 hours this afternoon and went back to buzzing again it also drained the battery from 100 to 0 in that 4 hours. Any help would be appreciated, the live chat was not useful at all!
Pretty much the same thing happened to me, I "cleared user data" which is as close to factory reset as possible. No data was lost, and it works now. Still has a bug though (I can't set alarms for some reason)
