Adding a LIDAR to the design would be useful in some cases and in theory should cost 5-10 bucks per LIDAR.

We're kind of rushed for space already, I think this could maybe be an add-on instead

What are some instances where LIDAR could be used in a smartphone? It seems like it would need to be well compensated with a larger battery. I think that a add-on for this might be a more accommodating idea.
