I just received my Phantom the other day and have been setting it up and doing "ground maneuvers" I continually get "Phantom Connection Broken" even when controller and aircraft are next to each other. I am using a Samsung S4 smart phone and I'm not sure if the problem is with the phone or the range extender/aircraft. I noticed in my searches that the Samsung Note 3 had similar problems. Any ideas on what problem I might have? Thanks for your time.
