Unlike previous models (such as the Surface Pro 4), there doesn't appear to be a diagram posted online showing the locations of the microphones, cameras, and speakers on the Surface Pro 6. The 5.0MP front-facing camera and 8.0MP rear-facing autofocus camera are pretty obvious. I know there's also security lights and a Windows Hello face authentication camera that I can probably locate by trial and error, though the infrared element needs clarification. But to make it simple, could someone please name each embedded device on both the front and the back going from left to right? There are 6 openings on the top front (some of which are hardly noticeable) and 3 on the top rear. Thanks in advance.
