January 3, 2013 – A bug in the Apple iPhone and iPad that is date connected that started on Tuesday January 1, is continuing to affect both iPad and iPhone users. Both devices carry a “Do Not Disturb” button and when scheduled the button either does not turn itself on or turn itself off. That means that calls to an iPhone go directly into the owner’s voicemail and the phone does not ring.
The bug first was discovered on January 1 when many users who had the Do Not Disturb function scheduled to shut off in the morning, did not. However, because of the holiday and because many people who really preferred not to be disturbed, the incident did not raise a red flag until Wednesday when the function continued to send calls directly to the voice mail.
However, it does not seem to affect all of the iOS6, Apple’s new software, users. Adding insult to injury, Apple chose January 2 to launch an advertisement promoting of all things, the Do Not Disturb function on the iPhone, which includes a video with the Williams’ sister of tennis fame.
The cure for this ailment seems to be the same cure that most computers are solved by – turn the function off and then on again. By turning off the function it appears that, the settings get reset so it automatically functions again normally. However, tests show it is not a cure for the problem.
Bugs that deal with dates are among the most common in operating systems as there are numerous edge cases and different exceptions such as the length of months.
The problem should be addressed by Apple on January 2 with a patch. iPhone and iPad users will most likely receive that patch from Apple at no cost.
