Your iPhone can be disabled by a string of Arabic characters, and there's currently no fix. Should have got an Android.
A new messaging bug has emerged that can crash iPhones and even switch them off.
Although it appears to be a harmless string of words and Arabic characters, just receiving the text will cause an iPhone with its screen locked to reboot without warning, or, if the iPhone is on, freeze or crash when a notification banner is displayed. Unfortunately, if the notification is displayed again when the phone restarts, it can get into a cycle of repeated crashes, effectively making your handset unusable.
The bug appears to stem from how the iPhone's notifications present unicode text, but it isn't clear why it doesn't seem to be affecting iPads or the iMessage desktop app. There are also differing reports on whether it's simply an iPhone to iPhone phenomenon or if it can be triggered by SMS texts from an Android handset or Windows Phone.
A fix in the works?
The issue is already trending on Twitter, and naturally enough many people have sent the message to others as a practical joke. Although Apple hasn't yet come up with an official solution, there are a few ways of quick-fixing an affected iPhone.
The bug only works when the message is displayed as a notification or on the Messages app, so asking somebody to send you another message will break the cycle of crashes. Removing banner alerts or intercepting the message on an Apple Watch or Messages Mac app will work too.
