i dont have discconets while flying but i get disconects when i start everything up,i turn on the mav then the rc then the phone and when it prompts me to open djgo or itchi i press djigo just once and it will open and ill see the camera for 1 second then get the red disconect, i close the app then do it again same thing then usualy on the 3rd attempt it stays green in gps mode, litchi doesnt seem to do that though, a few times it took more than 3 i gave up and used litchi for my flight, ill try a file cleaner app maybe,i have tried a new cord and changing my settings for phone to never sleep etc but still does it, i have tried a few versions of djigo too, some seem good for a dozen flights thenthey start dissconcects
