Thanks to a bug surrounding message pop-ups and the Arabic language, a gamer by the name of 'Sinfulz0r' has shown the world how to restart a friends phone just by text messaging them.
The scene is set in front of some click looking Tt eSPORTS peripherals and it is explained that there has to be a few things going your way in order for this to work. It is explained that the 'victim' phone must either be on the home or lock screen and have drop down message notifications active.
According to 'Facebook experts' (random people on the internet) what is happening here is a glitch with the way your iPhone processes the Arabic text - filling up the phone's RAM and forcing it to restart. Either way it seems to work every time he sends a message to his mother's phone.
