The iPhone 12 Pro became the first phone to have a back-facing Light Detection and Ranging (Lidar) camera, which enables more sophisticated augmented reality (AR). (Top-end Android phones use a similar Time-of-Flight, or ToF sensor.) Lidar can near-instantaneously detect depth and size, allowing for rapid and very detailed mixed reality functions for apps, such as furniture placement or full-body Snapchat Lenses. This should supercharge mobile AR spending and make such ads more feasible.
