Apple iPhone 8 is subject to several rumors, speculations, and leaks. Past leaks have suggested several features like wireless charging, infinity display, 3D camera, vertical dual camera, Iris scanner and much more. However, the latest leak seems to be trustworthy since it is coming all the way from the firmware of HomePod. The latest leak suggests that upcoming iPhone 8 could boost the infrared face unlock feature.

This Google HomePod’s firmware code base was firstly spotted by developer, Steve Troughton-Smith and has several references of “BKFaceDetect”, which presumably stands for BiometricKit. In the code, there is a new phone with the code name “D22,” which is assumed to be the iPhone 8.

The code also reveals that the HomePod is running on the full-fledged version of Apple iOS and depends on a shell app called SoundBoard for control. The leaked code base also confirms the existence of infrared camera, which could be there to detect a user’s face in the dark. The next iPhone from Apple is rumored to launch this year in September.
