First test for this DJI Mavic 2 Pro with Smart Controller & Capture video by using DJI Osmo Action cam.  Overall very satisfied with the range and the smart controller, the smart controller can be do screen shots and screen recording as well.  By the way it's running on CE mode in Malaysia and still able fly up to 4.7km.

Nice work.

Hi, we do appreciate sharing your work and flight experience with us! Thank you for continued support.

Can anyone tell me if it would be possible to use the RC (or smart controller)  and the dji go app at the same time? I.e one person controlling with remote controller and another person controlling the camera/gimbel settings from a smartphone that is not connected to the RC

No that cannot be done.
