ELI5: why in 2016 do cell phone cameras still have a better quality one on the back and a lower quality one facing you? would it really up the cost of the phone to just put 2 good cameras in it?

I realize you don't necessarily need 12MP to take pictures of yourself, but it seems like it would just be easier to slap 2 of the same camera in there.

The front facing camera has to fit between the edge of the screen and the edge of the phone, and people like having the screen as large as possible, which means that the front facing camera has to be really small, and it's hard to make good small cameras.  The one on the back is behind the screen and can be as wide as they want.
