I bought a built-in screened P4 + V2.0 before new year. At that time it was not allowing 3rd party apps so i changed it whit a controller without screen.
but at beginnig of april, i asked DJI if the situation changed or not, here is the reply;
“Regarding your email, I was able to coordinate this to our Engineers and yes, you can install some third-party software but we cannot ensure the remote controller is compatible with all software. Please try it with yourself as we do not have a tutorial for the third party app and confirm that cannot run any other flight control software like dronedeploy. The remote controller with built -in-screen only allows controlling fly by internal DJI GO 4 App.”
So i liked to learn if anybody can confirm that it Works or not. If it’s working i will rechange the controller.
