Not OP, but I believe he's talking about how the iPhone's large notch size is due to additional hardware used by face id. Having that size notch on the left/right side wouldn't be much better than in the center. Personally, I'd rather use my fingerprint anyway.

They have infrared and dot projector, otherwise every phone has mic, speaker, proximity sensor, etc. They chose to stuff everything in the notch, it wasn't necessary.
