If BEN decides to wreak havoc on your phone (or any electronic device really), there is one surefire way to get rid of him: A factory reset. Not only will this expell him from your device, but it'll also erase him from the world. He's come up with many counter-attacks for this though, so be patient when attempting a factory reset to get rid of him.

(Guess who fixed their phone with a factory reset? I DID! Guess who might've accidently erased BEN! I... did...)
