Apple has chimed in on the "Do Not Disturb" bug reported on New Year's Day, where the feature never turns itself off, thus meaning a user will never be disturbed again. The answer: Just wait; it will resolve itself.
In a support article on its website, Apple both acknowledged the bug is keeping iOS devices' "Do Not Disturb" feature active past its scheduled time, as well as mentioning a workaround. The Cupertino, Calif.-based company said that the bug will automatically resolve itself after Jan. 7, 2013.
"Do Not Disturb" is a new feature in iOS 6. Basically, the feature allows users to set periods in which their device will not notify them or ring. "Do Not Disturb" includes a scheduling feature which sets a timeframe during which the function is active; it is supposed to automatically shut the mode off at the scheduled time.
However, users noted that the feature wasn't working, starting on New Year's Day, 2013, or Tuesday.
Do Not Disturb scheduling feature will resume normal functionality after January 7, 2013. Before this date, you should manually turn the Do Not Disturb feature on or off.
To turn off the scheduling feature, tap Settings > Notifications > Do Not Disturb and switch Scheduled to Off.
It's just the latest in time and calendar bugs that seem to afflict iOS. iOS is famous for its Daylight Saving Time bug.
In order to fix the issue, users had to toggle the feature off and back on. Some said that the issue didn't get resolved unless their devices were rebooted.
