Is this the case with all batteries? I am assuming you have more than one?
BDOG, Thank you for your assistance , there is no tone from controller and RTH takes control.This is abnormal behavior for sure. Do you hear a tone from the Remote Controller as if the button for RTH is being pressed when it initiates the RTH? You can try and completely remove the DJI GO 4 app. Restart device and then reload. Write down all your custom settings within the app before removing it as those settings will need to be input again after reinstall.
BDOG , Since new I have had no problems wtth the drone , it only started occuring two days ago, I can start the flight but after 2 minutes it starts RTH sequence automatically.OK. So it seems it would not be a physically "stuck" RTH Button on the Remote Controller.
Is the drone new and this has been exhibited since new? Or has this drone worked without this issue in the past? Dropped Remote Controller at any point?
