Purchased on Jan 15 straight out of the box no IMU data is displayed in the boxes on the Sensor Page and Will Not Calibrate. I have posted this issue on DJI forum and received a response that they are working on the issue and should be corrected with a new firmware. I am wondering if ALL Units are affected or only Some Units? Please vote if you own a Phantom3 4K to see if this is widespread or not. Thank you! The poll I am posting is NOT for the standard compass calibration you perform before flying but instead is only for the Sensor Page where you can see sensor information in small boxes showing various data. Thanks.
