Randomly the sound stops working for audible alert notifications. When you lock screen, it clicks, and that audible sound works....however the text/calendar/phone call alerts don't work, they vibrate. I can then move the slider on the locked screen from sound to vibrate, then back to sound and it all works....for a little while. Then all the sudden even though sound is still enabled, all text/call/email/calendar items vibrate....however if you lock screen, it still gives the audible click, but that is the only audible sould that works until you toggle to vibrate, then back to sound. This is a company phone used for on-call, if I get a call at 3 in the morning, I need to be woken up by the tone, with this bug, this isn't possible. Randomly the phone will change times even though I am no where close to where a time zone change is. So the time will change back, but the alarm still uses the other time zones time. This causes the alarm to be off an hour...even though the time on the screen is correct. For instance 2 days ago, instead of the alarm going off at 6:30 as it was scheduled, it went off at 5:30 current time, even though the alarm was set to 6:30 and it was currently 5:30 and the phone showing 5:30, the alarm still went off an hour early??? WTF?? This for sure has to do with the phone auto switching to a different timezone even though I am no where close to a time zone change. EDIT:: Phone not root, 100% stock with VZW OTA JB update. Also meant to note, that when the issue with the alarm happened, I set the time to manual, however I would like to have it auto change time zones for when I do travel, so that feature working again would be nice. I think moto needs more testers before releasing products.
