Tech-savvy guys must be aware of this Most Annoying Prank! The “effective power text,” also know as the “text of doom,” has been crashing all iPhones that receive a specific string of Arabic, Marathi, and Chinese characters with the words “effective” and “power.”
Apple have warned about the ‘effective. Power’ text, which causes your phone to shut down, and has advised on how to safeguard against it. This is a surefire way to annoy all your friends- a bug in the Apple operating system means that if you send this text to your friends, it will reset their phone.
Only the people who know the characters will be able to send it to their friends, and once they do, the phone will crash.
It only works if you send it to someone who also has an iPhone.
Twitterati have found the prank funny and are using it to bug their friends.
