So I have played with the hand gestures and depending on lighting and clothing color I can get them to work a majority of the time. The scary thing is doing them without your phone or remote connected! Twice now I start the video gesture and wave it away. Now I start walking around and let it follow me for awhile then it looses me. I'll admit I have not read any manuals but there seems to be now way to get it to recognize you again and have it come down. the double arms up to summon it does not seem to work at this point. It does seem that after a short while it will descend where you can grab it.
