So I am an AT&T subscriber and a couple days ago I got an OTA update. I haven't noticed any changes so far, except that the stock Clock app is now broken. It starts to load, freezes for awhile, then says "Unfortunately, Clock has stopped." Every time. I use Clock heavily for alarm clocks and timers, and while I can get third party apps to replace it, I'd rather use the stock app. The weird thing is that my alarms are still going off, so it's like Clock is still running somewhere. Anyone else having this problem or know if I can fix it somehow?
