The green tint you’re seeing is only the focus‑guideline overlay that appears while you’re adjusting settings in Pro Video/Log mode – it doesn’t affect the actual photo, so the colors will return to normal once the picture is taken. If the preview still looks off after you’ve captured an image, try resetting the Camera app’s settings (Settings → Reset → Reset camera settings) or clearing its cache.
Should the issue continue, please report it through the Samsung Members app and attach the relevant log files so the team can investigate further
