This is how to attach a smartphone to the DJI Phantom 3 controller.  I demonstrate using the iPod Touch model listed below and also the iPhone 6 Plus.  I had the devices upside down on purpose, in case e-mails and messages came through while filming the video.  Don’t feel bad if this confused you too!  Out of the box, the DJI Phantom 3 controller’s smartphone mount is a little confusing.  It’s not immediately apparent that those little tabs pop up.  I know that mine were tight until I popped the up the first time.  They loosened up after that though.
