The bug was caused by a difference in formatting in the ISO calendar system versus the Gregorian calendar system. The feature would be left on past the scheduled time set by the user, allowing texts, notifications, and alarm settings to be missed. Many iPhone users experienced a bug with the Do Not Disturb feature when the calendar changed from 2012 to 2013. This was addressed for the iPhone 4S in iOS 6.1.1 which "fixes an issue that could impact cellular performance and reliability for iPhone 4S." Do Not Disturb In iOS 6.1, users reported problems with cellular connectivity. It has later been clarified by Apple that only the 4th generation iPad and the iPad Mini 1st generation or later will be able to use this. Location-based reminders do not work for iPads, even though they were promised to work on cellular enabled devices. As of October 2012, no solution has been provided by Apple.
