Discovered by Reddit users, this five-second video will force your iPhone to lock up and freeze, The Verge is reporting. All you need to do is click the MP4 file and watch it to experience the problem. Every iPhone tested so far seems to get locked up shortly after playing the video. The bug has been tested on multiple iPhones running the latest iOS 10.1 updates, as well as beta versions of iOS 10.2.
In our video demonstration of the bug, you’ll see that a link to the video, delivered via iMessage, will make iOS 10 play the file in the default player. It appears that the video is corrupt, generating a loop that causes the iPhone to crash around 10 seconds after watching it. We’re not linking to the video for obvious reasons, but it appears to only crash devices when it’s sent as a link rather than simply transferred as a file.
Apparently the only way to recover from the crash is to hold the power button and home button at the same time to perform a hard reset. An iPhone will work normally once it has rebooted.
A similar bug was discovered last year, where a string of text disabled the iMessage app on iPhones, which was addressed by Apple with an iOS update later on. Similarly, Safari started randomly crashing on iPhones due to a software issue earlier this year,, that was quickly resolved by an iOS update as well.
Apple is yet to issue a statement on the new crash problem. In the meantime, check out the video here demonstrating the bug.
