Apple iPhone users have another possible problem to watch out for. Resetting the date to January 1, 1970 in Apple devices such as iPhones, iPads an iPods, running iOS 8 and above, could permanently brick the device.
Apple partially confirmed a widely reported rumor in its official support site. "Manually changing the date to May 1970 or earlier can prevent your iOS device from turning on after a restart."
Apart from indicating that, an upcoming software update will squash the bug. The company has also provided few other information about what went wrong or why the iOS devices brick. Meanwhile, 9to5Mac, has posted a video showing the bug in action.
The report also says, "this bug affects any iOS device that uses a 64-bit processor and is running iOS 8 or newer, including iPhones, iPads, and iPod touches," but a 32-bit processor should be fine.
However, some Reddit users have explained the theory that timezones, may be the culprit in the bug. The fact that January 1, 1970 sets the clock to a value less than zero, which causes the crash.
