Dark circle on front camera

Hello, Acefrom96.

Thank you for using Apple Support Communities.

From what has been read on your post, you're seeing a dark spot whenever you use your camera on the iPhone. It's good that you've checked over the camera to make sure there was nothing damaged.

Does the dark circle appear after taking photos or videos?

Have you tried different lighting when taking photos or videos? If you see a flare, haze, or spot near the edge of your photo or video

Try cleaning the camera to see if that helps and remove the case if you have one: If the camera or flash on your iPhone, iPad, or iPod touch isn't working

"If the camera isn't working

1. Remove any case or film that might block the camera. A metallic or magnetic case or camera attachment might interfere with the camera on your device.
2. Test the camera by trying to take a photo. 
3. If the photo is blurry, clean the front and back camera lenses with a microfiber cloth. If you see dirt or debris inside the lens or if the camera lens appears to be misaligned or blocked, contact Apple Support for help with your iPhone, iPad, or iPod touch.
4. Restart your iPhone, iPad, or iPod touch. 
5. Test the camera again by taking a photo. If your device has a front and rear camera, check if one or both isn’t working. To switch cameras, tap the rotate button ".

Keep us updated.

Cheers!
