Here are some steps you can try to address the shadow problem on your photos:
1. Check Camera Settings: Go to your Camera app settings and ensure that any additional settings or effects that might be causing these shadows are turned off. Sometimes, updates can reset certain settings.
2. Reset Display Settings: Occasionally, display-related issues can affect how photos appear. Try adjusting the display settings or resetting them to default to see if that resolves the problem.
3. Update to the Latest Version: Keep an eye out for any new iOS updates. Apple often releases updates to address bugs and issues reported by users. Updating to the latest version might fix the problem you're facing.
4. Check Photo Editing Apps: If you use any third-party photo editing apps, they might be causing the shadows. Try editing a photo directly from the native Photos app to see if the issue persists.
5. Reset All Settings: This step should be handled with caution as it resets all settings on your device. Go to Settings > General > Reset > Reset All Settings. This won't delete your data but will reset preferences like network settings, display settings, etc.
6. Contact Apple Support: If none of the above steps resolve the issue, consider reaching out to Apple Support. They can offer more personalized assistance or direct you to a solution specific to your device.
