Hi,

I have a Phantom 4 and using the DJI GO 4 app on my Nokia 6 and having issues connecting the App to the controller.  I have observed and tried the following:

• The once loaded checked the firmware and updated the controller, but when "Enter Device" it was saying not connected in red.
• I tried restarting the App and turning the drone and controller on in different sequences but it still failed to connect when clicking on "Enter Device"
• On the initial splash screen where "Enter Device" is visible have noted sometimes this says connected with a green circle, even though the USB cable is not connected to the controller.
  

Any ideas or advice would be useful, I have also tried activating USB debugging but did not change anything and unsure if there are any best practice settings for the USB etc?

Thanks ,

Anja

Forgot to add this:  Phone is Android is version 7.1.2 and DJI GO 4 is version 4.1.14 (411-gpPhone)

I would say to try another device.  Problem with the Nokia.

If re-installing the APP does not work, you can change to another recommended mobile to verify. You can find the recommended list here: https://www.dji.com/phantom-4/info#downloads
