Using iPhone XR, and the only way it fits in the controller harness is vertically, but the camera view is always on landscape mode (even though my iPhone's portrait mode is not locked).  How can I correct this?

Hello there jeremyjwatts. I am sorry for the trouble this has caused and thank you for reaching out. Can you please try using a different mobile device to see if the issue will still persist? For reference I will post the list of recommended mobile device for the DJI Phantom 3 Pro below. Please keep us post for further assistance. Thank you.
