A short video, circulating on the internet, is causing some iphones and ipads to crash in just seconds.
Several "Reddit" users, and technology websites say the video shows a man performing a magic trick with a deck of cards, and then the word "honey" appears on the screen.
The video then tries to re-play itself, but it quickly causes the phone to freeze.
Some reports say resetting your phone could help to un-freeze it.
iphones running iOS 10.1 and beta versions of 10.2 seem to be the most vulnerable.
