There is a video that is being distributed as a prank, which slows down any iPhone and makes it eventually crash. The video from Miaopao, a video sharing app, plays normally on an iPhone for about a minute and then eventually freezes the phone making users to forcefully reboot the phone.

Most people are not aware of the fact that a video like this even exists and they end up being pranked until their phones are eventually taken to the home screen with the spinning logo on a black screen.

This bug affects every iPhone that is running iOS 5 and above which means it affects devices from the iPhone 4 to Apple’s latest offering the iPhone 7. The bug depends on how old the phone is i.e. the older the phone the faster it will freeze.
