When shooting in Pro Mode (DNG + JPEG), the DNG files appear rotated 90 degrees in Samsung Gallery, even though the matching JPEGs from the same shot are correctly oriented after export from Lightroom, Snapseed or any software exporting DNG.
The issue persists after cache clear, camera reset, and latest firmware update. It occurs with both main and telephoto lenses and is visible directly in the phone’s default Gallery app (no third-party software involved).
This confirms that the camera is writing incorrect EXIF orientation data to DNG files at capture time. Please escalate this to the camera firmware / image-processing team for verification and correction in a future update.
