Windows users must be familiar with the "Blue Screen of Death" (BSOD) aka a blue screen error message that appears when the system crashes.
If it's sticking, then the only way to make it back to work is by restarting.
Such a thing was not the monopoly of Windows alone, but may also occur on the Apple iPhone 5S.
As reported by The Verge, a number of users reported a case in which the popular smartphone stopped working (hangs) with a blue screen and restarts by itself.
Blue screen incident was allegedly related to a bug in the iWork application suite which is bundled with all the latest iOS devices.
A video shows that the iPhone 5S BSOD appears when users perform multitasking, move between running applications.
Some users also reported that they often do the iPhone 5S randomly reboot itself while in use.
Apple itself had previously released the iOS 7.0.2 update to address security bugs scren lock screen on the operating system. But the sudden reboot problem still occurs.
Users who experience this problem channeling complaints through a number of threads on Apple forums and Twitter posts. Crashes associated with iWorks reportedly can be muted by turning off iCloud sync feature for apps Pages, Keynote, and Numbers.
