Factors that may negatively affect the quality of the iPhone 16 camera:
Dirt on images: This is influenced by factors like zoom, lighting, hand movement, aperture, and the specific camera used (front or rear).
Flash reflections and internal reflections: These can appear when there are light sources in the frame.
To improve photo quality, consider these solutions:
Adjust default settings: Go to Settings -> Camera -> Formats and set High Efficiency for camera capture, a resolution of 24 megapixels, and enable ProRAW and resolution control.
Force-close the Camera app: This can help resolve minor errors.
Restart your device: Press and release the volume up button, then press and hold the volume down button until you see the Apple logo.
Contact Apple Support if the issue persists.
