Focal Length is FIXED in auto focus mode

[hit2sjtu]

SPECIFIC ISSUE ENCOUNTERED

We are using ARCore for some development, but we found that the focal length obtained by the ArCameraIntrinsics_getFocalLength is the SAME for all frames when auto focus mode is turned ON. We can confirm the camera is changing focus and the result of same focal length during the process is kind of surprising.
We see the behavior on multiple devices such as pixel, Xiaomi Mix2S .etc

VERSIONS USED
