Can I suggest to DJI to add voice control via mobile phone?. I.e. press a button like calling up Siri or Google assistant and issue commands like fly to xxx location (preset) come home, hover, land, circle, take pano etc. Maybe more effective then gesture and fiddling with settings.

Take off - Beam me up Sparky!

That would be awesome to add that in.

I just registered solo to reply to this thread! Yes yes yes, please do this! I don't even own a drone yet, but I'm pretty set on the Spark, and I've been trying to see if this was available or could possibly be available in a future firmware update. Sure would be cool to use voice controls through your phone rather than gestures. Would be awesome to instruct it to move back 5 feet, or 10 feet, or initiate a  maneuver like a Circle, or Follow Me. Regardless of whether or not this ever becomes a thing I believe I'll be looking forward to playing around with the Spark.  

Please no button press - I’m busy flying.
Don’t forget the voice command “clear messages”.
