Have you verified that the images in question actually contains orientation information? Use ExifTool or some other application capable of reading these data, and verify that they are there. If that's the case, you need to post a sample of one such problematic image.

As @Nadahar says, a null here suggests the metadata isn't there. If you can see metadata in another app (e.g. exiftool) then please attach a sample image here to allow further debugging.

I'll close this for now as we do not yet have evidence of a bug. If you believe a bug exists, please attach an image that demonstrates the problem and we can reopen this. Thanks.
