Broadcom Wi-Fi SoCs on modern Smartphones, such as Google's Pixel 7 and 8, come with built-in functionalities for ToF proximity measurements. We analyzed similar functionalities on former chips related to Apple's Auto Unlock feature in the past. In this work, we search for modifications made since our last analysis, evaluate functionality and accuracy of the system, and elaborate innovative use cases. For this, we use firmware reverse engineering and modification.
