that is cool!
it is crappy weather here so i am grounded. thank for sharing.
by the way,i noticed you taking pictures and was wondering if you can do video and take a picture without interrupting the video?
i am guessing yes.
I think the screen capture / record function is built into the xperia Phone and is not part of the DJI app. Usually you will have to root the phone to run another app to capture the screen on the Android Platform
