Apple is trying to ensure that the iOS ‘Do Not Disturb’ glitch that appeared on New Year’s Day is fixed by 7 January 2013.

Apple said in a statement that the ‘Do Not Disturb’ scheduling feature will recommence normal operations from that date. "Before this date, you should manually turn the Do Not Disturb feature on or off," Apple said.

The iPhone maker received many complaints that the feature, which silences calls, alerts, and notifications when enabled, had been jammed in the ‘on’ position since 1 January.

Apple, confirming the problem, said that after New Year’s Day, the Do Not Disturb mode stayed on ‘past its scheduled end time.’ Not all the users of iOS 6 seem to have been affected by the problem.

Apple had released the Do Not Disturb feature in June 2012, along with other iOS 6 features that include a modernised Maps application, Siri on the iPad, Facebook integration, and FaceTime video chat over cell networks.

But the mapping application turned out to be faulty, as it gave users wrong directions and displayed incorrect landmarks, for which the Apple CEO Tim Cook apologised.
