My experience so far with Mavic Pro and Android.
On first DD flight, it launched, flew the route, took photos, but they were out of focus.
A few days later, I tried to redo the route to get in focus pics. Mavic got to first waypoint and just hovered, no photos, no following mission, nothing.
Yesterday, tried again. Took three batteries. Using DJI pro, went up to altitude, manually set camera focus and exposure, killed DJI GO, started DD. Went to first waypoint and drone just hovered. Tried to get it to go but it just sat there. Finally brought it back and changed battery.
2nd try, same procedure, Use DJI GO, up, focus/exposure. Kill DJI Go. Start DD. Off to first waypoint. This time it starts going, but it is not taking photos, and the camera is pointing at the horizon rather than down. Try to force camera down, but it just returns to horizon. Return to home.
Last try, fresh battery, Use DJI Go, Up, focus/exposure. Kill DJI Go. Unplug controller from tablet, plug in to tablet. Select DroneDeploy. Start mission. Same as before. Goes to first waypoint to start mission but camera immediately goes to horizon.
So, not having much luck finding that perfect sequence of events to get this to work on Android. And using DJI first to go up, hover at altitude, set camera, close DJI, Start DroneDeploy, get everything loaded there, uses up about 10% of the battery so...
