The two cameras function as follows:

The primary camera produces clear images with great color reproduction. It captures the preview image of the person or object. If the primary camera lens is blocked, the preview image will be unavailable.

The secondary camera is used to gather extra brightness and contrast information. If the secondary camera lens is blocked, the preview image will not be affected. However, the contrast information provided by the secondary camera is missing, which will result in a poor image quality.

When taking photos, ensure that both cameras are not blocked or covered.
