> GPS might be helpful for drones (though it should be on the drone, not your phone) but there is absolutely no reason to use it for something like a phone stabilizer

Wouldn't the app need GPS permissions just to show you where the drone is on a map, etc.?

No, it doesn't, since the drone will show you where the drone is. For your own location relative to the drone, it is though. You can do without, but just showing home (take off) location on the map is not ideal.

How so? The drone can send its own location. The app might show you your location on the map, but that's not mandatory for operating a drone. It is a good user experience, I admit, but you can operate drones without this.

And it doesn't explain why phone stabilizers require location access. Tried it myself with the OM 5.
