wondering if anyone else has this issue and might now the answer? I'm using UgCS for DJI on a Lenovo Tab 3 running android 5.1, and this is the only android device we have, everything else is apple (I bought it expressly to use with UgCS). When I plug in the USB the tablet asks which app you want to use it with, DJI GO or UgCS - you can't chose more than one. So I can do my preflights and calibrations etc... in GO but then I have to unplug, replug and chose UgCS in order to fly the mission. That's not actually the problem, I don't mind doing that.
The problem I have is that DJI GO 4 then doesn't log any information about the flight, because it's not using the USB connection while UgCS is. To begin with I didn't even notice this because I was running one drone (a P4) and just using some simple forms for log book info like battery use, flight times, maintenance etc... But now we have 3 drones and the logging feature in DJI GO 4 is actually pretty useful because we sync it to Healthy Drones for maintenance records. We're also integrating all our records into a database with the intent of pulling the flight data directly from the DJI GO app.
So what I want to know is; does the latest version of android (7?) allow the two apps to share the data from the USB cable, like my iPad does with DJI GO and DronePan? If it does then it's a simple matter to upgrade the tablet. If not then I'm not sure what the solution is, because there's no sign of an iOS UgCS app.
