Hello, that was happening to me with my Galaxy S8+ and it was mind boggling because I tried every single trick I knew to reset, reinstall, clean cache, calibrate, and try different devices but then all of a sudden the other day I accidently used the DJI app and signed into the app and updated it (meaning the DJI Go App) and now it's working fine!! I'm thinking DJI has somehow figured out a way to backdoor getting past there crazy take over of all drones!! I really don't know but you may want to try that...???
