I believe it will not be more than 2 months since the launch of iPhone 12, and more and more news leaks. This time it comes from a picture of a suspected iPhone 12 Pro glass back case posted by Mr. White on Twitter.
This picture clearly sees two back shells, the larger one should be the iPhone 12 Pro Max, and the smaller one should be the iPhone 12 Pro.
Although the two glass back shells are also designed with three lenses, the Pro Max one has an additional "hole" at the bottom right of the lens module, which looks similar to the iPad Pro 2020 LiDAR. That is to say, only the iPhone 12 Pro Max will be equipped with a LiDAR sensor for optical detection and ranging.
