It was previously covered that Apple will include a LiDAR scanner on all iPhone 13 models. At this point in time, only the iPhone 12 and iPhone 12 Pro Max feature a LiDAR scanner. However, it seems this year it will be the same and the iPhone 13 Pro models will be exclusive to house the LiDAR scanner. Scroll down to see more details on the forthcoming iPhone's camera features.

The LiDAR scanner is a 3D depth measuring sensor that measures objects up to five meters away. The tech basically enhances the augmented reality experience and also gives room to other features. At this point in time, Apple has incorporated the LiDAR scanner on the iPad Pro series and the iPhone 12 Pro series. Initially, the sensor made its debut on the 2020 iPad Pro and now it will make its way to the iPhone 13 Pro series.
