Just a quick update on DJI Go 3.0.1 with the latest firmware 1.0.3, 6 Dec 2016....
Had a flight this morning on my Mavic using DJI Go 3.0.1 and realised that the short-cut buttons, C1, C2, and the 5 way button no longer works with the new firmware... Clicking on C1 or C2 brings up the camera/video configuration screen. The 5 way button does not do anything at all, regardless of what is defined in DJI Go 3.0.1...
I then tried flying with the latest version of DJI Go 4 on android, and the short-cut buttons works as defined in DJI Go 4.. Also found out that the Here map in DJI Go 4 now follows the aircraft, but unfortunately, the map is just a complete blur with no map details to discern where you actually are on the map... Zooming in doesn't change anything at all.. Pretty useless map actually... Just wish DJI had stayed with Google maps instead of switching...
