Apple's newly released iOS 7 looks very cool, but there are too many bugs. Although this is a necessary path for the initial release of an operating system, iOS 7's performance is really far from satisfactory.
According to foreign media reports, iOS 7 has encountered another issue, mainly causing incorrect calendar time display when switching to daylight saving time.
Users report that after switching to daylight saving time, the "current time" line in the iOS 7 calendar will be one hour ahead, but the time displayed before the "current time" line and on the system notification bar is correct.
Although this defect does not affect the calendar and alarm functions, it still makes people feel somewhat amused and frustrated.
