Has the thickness of phones reached a physical limit?

Not much more contect needed I think. (If yes, what stops us?)

There's nothing directly keeping phones from getting thinner.  There's a number of things that will make it unlikely anybody would decide to, though-- the biggest of which is probably the camera.  Cameras are effectively setting the phone thickness limit right now, to the point where the common design workaround is to make the camera stick out.  Without the camera, you could take all the parts in a modern phone and lay them out so it was even thinner.  Even something like the new iPhones could be thinned out-- their innards are still a sandwich of multiple layers.  At a very simple level, you could just put the battery, screen, and mainboard next to eachother instead of on top of eachother.  The result might be ugly and wide and so forth-- but it would be substantially thinner than currently without having to even invent anything new.
