Contributor guide
Research direction
Start by reproducing the issue in the Nextcloud Android app using a locally downloaded photo with EXIF Orientation 3, then compare it with the same photo opened after local deletion. Trace the offline/local-storage image display entry point and verify that the photo is rendered with the EXIF rotation in Android 15; done means the offline view is no longer upside down while the online view remains correct.
