Online speculations suggest that the next-gen Pixel handsets will ship with some sort of a hardware-based 3D facial recognition feature that will be more secure than the software-based options available on most Android devices thus far. Whether the new feature will employ a Time of Flight (ToF) sensor like the iPhone X-series devices is anybody’s guess, but Google is now said to be collecting facial data from people around the US for its next-gen facial recognition feature in the Pixel 4 and Pixel 4 XL.
