A glitch in the iOS
There was once a time when sending a random set of characters to another person’s iPhone would result in their phone rebooting. To do this, all you had to do was text them the characters, and there would be a 50/50 chance that it would cause their phone to turn off and on again.
This guy discovered the sacred passage and decided to give it a try. Despite the other guy not being on board with the prank, he did it anyway. Legend has it that the friend’s phone rebooted and that he sent a flurry of angry texts to the original texter.
