The iPhone 5s has been presenting a strange display to some users recently — the blue screen of death, presumed before now to be a uniquely Microsoft feature.

The problem, spotted first by The Verge, has been reported by several users in various threads on Apple’s support community, as well as MacRumors’ forums. Some users have also taken to Twitter to vent their frustrations.

It appears that the blue screen of death may be linked to Apple’s iWork apps — Pages, Numbers and Keynote. One user captured the appearance of the blue screen on video.

Apple’s iOS 7 rollout has been rather bumpy. Earlier this month, the company said it was working on a fix for problems with iMessage, with suggestions that it may be testing a new iOS update – iOS 7.0.3 — which will bring a fix to the software issue. It also recently patched up a vulnerability with its lock screen password system by releasing a new version of iOS 7.
