Hi guys, I recently went to Mexico, while flying I kept losing signal, strong interference was in red on my android tablet using DJI go 4 app. My mavic was less than 400-500 yards away, trees was an issue maybe on one occasion, not thick trees. The issue was every time a flew, I would have to reconnect the tablet and start the app, any tips, range extenders??? hope I can get help or is it the bloody app?
