If the DJI Fly App is pre-installed on my RC2 controller for my Mini 4 Pro, why do I need a wireless connection to an Android phone?

Will you clarify please? In order to use the Pro4, with 'say' waypoints,
Yes

Do I have to use a phone (I have the RC2)?

No

Do I have to share my location?

No and your equipment doesn't share your location except that the drone shares it's location with the controller and vice versa.
You worry unnecessarily about something that doesn't happen.

Hi B and M,
Not 100% clear, but I suspect it shares as much as it can, if allowed to, even though it says it doesn't.
It appears to be the way of the modern world.
I don't worry that much, but don't like it.

I was listening today, about the slimy tricks F'book has used. That lovely family sharing site.

What you suspect just isn't true.
You need to ease up on the paranoia.

Hi M,
I can assure that I'm not paranoid, just don't like the trend, that's all.
