Nothing on it is decoration. Every key is a real control: the keypad jumps through the film from 10 to 90%, OK plays, ✱ mutes and # goes full screen. Hold OK and push it like a thumbstick to spin a 3D control dial for speed, volume, captions and tracks. The side rocker sets the volume, the camera key snaps the frame, pulling the aux cable cuts the sound, and when the battery (the video) runs dry, the phone charges itself ϟ(˘ᵕ˘)ϟ
