There were a few postings that suggested that you can turn on flight information in the video, but I have not be able to do this on the Android app. Alternatively, if there is any way of saving the GPS information from the flight, I would like to be able to match that with the video output.
Thanks

I would also be interested in this.  I have an app that records flight info but does so to a .csv file.

Not available in the DJI Vision app, some here use Flytrex or 3rd party apps.
