I just received my first drone. Phantom 3 standard I have calibrated the IMU. The controller. Downloaded new firmware. Connect with the. Copter via iPhone 6s I see video through the camera and can move the camera. Red at top of app says compass needs calibrating. Intake the unit out in my field and try to calibrate and it persistently says magnetic interference try new location. I moved to multiple locations even driving across town with same result I connect my phone to the phantom wifi while trying to calibrate with the DJI dance. Planning to try customer service in morning. Feeling like compass must have been damaged during shipping.
