Yes, definitely it is the 'Force Stop' operation that allows Drone Deploy to work and also allows DJI GO to control the Phantom 3 Standard from an android device. With both DD and DJI GO installed on my Samsung 5 phone, neither will work if the other is not Forced Stopped.
With DD un-stopped, DJI GO shows 'weak signal', max altitude =0, Return to Home altitude = 0 and when the quad is powered up the camera gimbal goes bonkers.
With DJI GO un-stopped, DD shows no waypoints selected so it won't allow the quad to take off.
Both apps. are loaded on my S5 phone, select Apps, select 'Settings' (white gear over blue square icon), scroll down through settings to Application manager (4 white squares
in a blue circle), scroll down in App. manager to app. DJI GO and hit FORCE STOP. This allows DD to work on the quad. To then fly your 'point of interest' route using DJI GO to shoot the side angles of the scene do the same procedure and FORCE STOP D.D. and activate DJI GO by clicking on the icon for it on your device.
Now to attempt to upload the images (data).
