How do you download your completed (edited) videos without sharing them?  After I 'complete' editing I have the option to share... but I do not want to upload it to a service I just want it on the spark's sd card (or my phone's sd).
I see the edited videos when I select create, but they are not on the sd card.  
thanks.

Sorry i don't have an android phone..
But should be similiar... instead of FlightRecord, there should be something called video cache or exports or something like that

For Android devices:
Connect your device to a computer via a USB cable and go to "DJI/dji.pilot/FlightRecord" (for DJI GO 3) or "DJI/dji.go.v4/FlightRecord" (for DJI GO 4).

If you are using an Android device, you can try to find the edited videos by this route: GO4: DJI/dji.go.v4/VideoEditor/production

I can only speak for iOS, but maybe it's helpful:
Press share, press the round button with the three dots, press save Video. Done, saved to the camera roll.
