Why is the direction information sometimes attached to images and sometimes not?

Orientation information may not be recorded if a magnet or other magnetic item is placed near the camera. In such cases, it is recommended that you calibrate the electromagnetic compass by moving the camera in figure eight before taking photos.

In addition, you can check the status of the calibration of the electronic compass with the presence or absence of COMPASS_CALIBRATION by using State which obtains the state of the camera through the Web API.
