Apple’s latest iPhone 5S has an unexpected feature: the Blue Screen Of Death (BSOD). While it’s typically an error found on older Windows PCs, a number of iPhone 5S users are reporting random reboots on their handsets following a BSOD. The blue screen reboots appear to be iPhone 5S specific and are largely occurring with Apple’s own iWork apps that come free with all new iOS devices. Videos detailing the issue show that multitasking between apps seems to trigger the BSOD. iPhone 5S users are also reporting random reboots during device use. Apple has released iOS 7.0.2 to primarily fix lock-screen security bugs, but the latest version does not address the reboot issues. Several threads on Apple’s support forums highlight the problem, and a number of Twitter users have also expressed their frustration. One workaround to alleviate the iWork-related reboots is to disable iCloud syncing for Apple’s Pages, Keynote, and Numbers apps.
