haven't had any connection problems haven't flown out to far (500-600m)...I always start the drone, then controller, then the app... BEFORE... I plug it into the phone... always hooks up OK, binding, GPS test.... flying!!!!... I also have a cheap Samsung phone, J3 I think... 1.3 quad... only problem I've had is yellow, purple flashing... switched to manual camera mode took care of that, hopefully until the next cam. update.... good luck
