True. This could have been implemented by manufacturers, like Nokia did with the shells for their 33xx-series phones. Instead they seem to be focused on style rather than usability.

I can’t think of anyone in my social circle who owns and uses a phone sans-case in exactly the way the manufacturer sells it. It’s in a wallet case, or a normal case, or it’s got a clear jelly case, or a case that facilitates mounting in the car, etc etc.

I am always surprised at the colour of my phone on the rare occasion I take it out of its case, it’s white, and my case - that entirely wraps it - is black.
