I personally don't. I try to avoid having to push too many buttons before and after the flight. If I turn on airplane mode, I will most certainly forget to turn it off, and that can be bad.
Never. IPhone 7. 150 flights, zero problem. Pro: always an updated map besides your GPS location.
I have a brand new Mavic drone (and I'm a new pilot), and want to know if I use a dedicated device (Samsung S7 Edge) will that be fine if I don't have cellular service. I won't have a Sim in it, so will it still gather flight data? Do I need to connect to a service before each flight? I see people mentioning downloading map locations etc, and I'm so green.... I'm hoping to get some direction. Or do I just use my current cell phone and just turn to airplane mode minutes before flight? Help help help please!You must pre-cache the maps for this to work. Open DJI GO 4, and hit the menu in the upper right of the splash screen (first screen that comes up). You'll see the Offline Maps option there. You don't need to be plugged into the controller or connected to the Mavic to do this. I too fly in airplane mode, even though I'm on a dedicated device without cell service. I also have USB Debugging turned on in Developer Options (Android), which some have said "might" help with video lag.
