Why does it seem there's fine dust inside the camera of the Galaxy device?

All Samsung phones undergo strict quality control measures, including activities to prevent foreign matter and rigorous inspections, to ensure they meet our quality standards. However, despite our best efforts during the manufacturing process, there may occasionally be instances where fine dust is present within an acceptable range, and this does not affect the camera's performance.

Furthermore, if there are no substances or particles visible when taking or reviewing pictures, it is not considered a product defect. Therefore, you can use the device with confidence.
