iPhone: text message leads to total crash
A simple emoji combination in a text message on iMessage should be enough to crash the iPhone. However, this only works with iOS 10.
Again, a few tinkerers came up with a way to crash the iPhone. As recently as December, it was enough to send a manipulated contact file to another user and cause the iPhone to crash. Now four characters should be enough to crash someone else's iPhone with iOS 10.
iPhone crash: this is how it should work
According to the instructions on preston159.com, four characters should be enough to cause the iPhone to crash. A white flag emoji, a character called VS16, a zero, and a rainbow emoji. It is also mentioned here that this combination only crashes iPhones from iOS 10.0 to 10.1.1. Therefore, users should urgently update to iOS 10.2.
However, the message cannot be sent directly from the iPhone. You have to get them from this side copy and from the iCloud paste directly into a note. You then have to share this with your contacts in iMessage on the iPhone in order to exploit the bug. For iOS 10.2 and higher, there is a manipulated contact file on the site that you have to send to a contact via iMessage in order to crash the iPhone. Above this link it should then be possible to repair the destroyed Messages app.
