Mavic Pro uses Occusync instead of Wifi so you wouldn't see the same issue. Spark uses wifi mainly and if there's a lot of interference, you will see the disconnects. I have tried to go back to flying without an OTG cable but have had very limited success so I only mainly fly nowadays with the OTG cable.Stupid question, I also have a Mavic Pro platinum. If i take out my Mavic Pro and try to fly it on the same spot? If it is definitely interference, should the Mavic Pro Platinum also be disconnecting and connecting? I haven't tried this but if it does disconnect/connect then I can "scientifically" somewhat say, yes it's definitely interference. If it doesn't do it??? Hmmm...
