Turn up volume by text (for when your phone is lost in the eternal depths of the cushions.)
Left your phone on vibrate or silent? Then the tentacle-couch monster snatched it away but not your friends' cellular device? Good news! Just have a friend text you the simple and easy phrase of "SCREAM_" then wait a minute and all your phone, and rescue it from the dreaded tentacle-couch monstrosity, and remember one thing! IT is more afraid of YOU, than YOU are of IT!
