It looks like a new bug has been discovered in Apple’s iOS that will crash your handset when a message is received. The bug was originally spotted by Italian blog Mobile World. Tom Warren from The Verge has tested the bug out and released a video of it in action.
The video below which was posted on Twitter shows the bug happening on an iPhone when a specific message is received.

The message is a character from the Indian language Telugu, when it is sent to Apple devices on iMessages it will cause the device to crash. It looks like once this has happened the messaging app will no longer open the messaging app.
The way to fix this is get one of your friends to send you another message and then open the app. Once it is open you will then need to delete the message with the character in it.
