Blinking Controller Signal (what does it actually means?) and video transmission

[oikonomoupetros]

In any case is it better to use the usb in the left or the one in the bottom when flying?
Will this give better distance-signal?
I am trying to fly my Mavic in Mykonos island and can go up to 850 meters distance. Then it will loose all bars and video feed.
Also a message strong interference will saw up.
iPhone 5s,
Mavic n controller updated.

bottom port is always better and more stable the crap cable DJI supplies will break down after a few flights 850m is fine it depends on where you are flying and what interference you have in that area go fly many places and see how range is affected. with all the new NFZ anyone is gonna be lucky of they can fly more than 500m soon unless they are in a desert
