What are these two small circles at the bottom right of the iPhone 12 Pro lens?

The circle in the small box is a noise-reducing radio microphone. The circle in the big box is the exclusive LiDAR optical radar scanner with three lenses of iPhone 12 Pro series.

It can have better ranging performance and focusing ability. It can be helpful in AR application or night shooting. In addition, the 12pro series has specially added the format of AppleProRAW for users who like to take pictures, so that you can keep more details of the material when shooting images, and you will have more freedom to adjust more places during post-production.
