I'm a new user of DJI products (in fact I'm still waiting for my Mavic to be shipped) and recently downloaded and installed the latest version of the DJI Go App from the Google Play Store.
However, there are two things that I don't like about the app:
First, it still doesn't support the new Android permission system, where an app requests permissions at runtime when they are needed. Second, it requests tons of permissions when it is installed, and for some of them, I simply don't see why the app would ever need them.
This is especially true for the "Phone" permissions: The app is granted the permission to dial phone numbers and to redirect outgoing calls (!). I have no clue how these permissions actually work and if one would be notified if an app tried to use them, but nonetheless, I would like to see them removed - or at least explained why they are needed.

I have no idea of that.
I think lots of app will granted these permission. Maybe you can just ignore that.
