The iOS device suffer from another alarm bug backlash. Numerous iPhone users complained that instead of going one-hour forward the device went back one-hour instead.
On the morning of March 13, 2011, many iPhone users discovered that their devices were two-hour behind schedule. My Gadget News reports:
…..today was the first time the issue actually trended on Twitter. On Sunday morning it seemed everyone was full of complaints about the unexplained two-hour mix-up.
If your iPhone is set back, then restart the device. You can also switch to “airplane mode” and then regular mode.
This is not the first time, the iPhone had been affected by alarm bug. In November 2010, after switching from daylight saving time, iPhone users in Europe woke from sleep late as the alarm of the device did not go off on time. The iPhone bug again reactivated in the first two days of the New Year. This time, the non-repeating alarm of the iOS devices did not go off in the first two days.
