BG105515554 Had the same issue..for the calibration it made a difference when I turned on the controller and synced the drone, then with a clear view of the sky 0 satellites became 18, and it could fly. Turning both off and then on reset it and it all calibrated correctly.

BG105515554@BG152018512 Video is jumpy from drone movement, still pics transfered by wifi look good on the phone but not useful to enlarge much..and video recording length on mine is poor..0 to 14 seconds..then starts another clip..even at close range. Not real useful for video needs.

BG105515554 This drone connects very well usually and its WiFi should show up quickly in your phones list of available wifi's in settings, then select it. If it drops the WiFi..it could be a setting in the phone to only pick WiFi with internet?? must try it away from home and other WiFi sources and test. Usually a great drone unless faulty. Good luck.

BG105515554 Very sad it didn't come back...but not connecting properly to at least a few satellites can be a problem. Anyone reading this should avoid real flights with a "0" number of satellites, and avoid crashes like I had. I turned either the remote or the drone off then on(with GPS on) and after the joystick sync to the drone was done...up to 18 satellites finally showed up, flying easy, and no drones lost or crashed. With calibrations completed it has everything it needs to fly...and find its way back to the takeoff spot if needed.

BG105515554 What part doesn't work? Batteries?, calibration, startup?
