Several iOS 6 users are reporting that their iPhone’s Do Not Disturb feature isn’t deactivating as scheduled this morning. iPhone owners at the Whirlpool forums and the MacRumors forums are describing the issue. Do Not Disturb lets users silence iOS 6 alarms for a given period of time. Note that not all users are affected. My iPhone disabled Do Not Disturb this morning at 7:00 AM as expected.
This isn’t the first time Apple’s iPhone has struggled with New Year’s Day. In 2010, single-use, non-repeating alarms failed to sound. Later that year, alarms struggled again with Daylight Savings Time.
