Samsung is filing patents for some interesting technology and it is not foldable rather modular and interchangeable camera.

The sketches of this phone show different shapes, suggesting the range of devices will have different camera to choose or pick

Samsung files Patent for Phone with switchable camera module

Then there is something else, which is thin like a Phone, has a bit larger round-shaped camera module, and a heftier camera like grip on one end. It has a hardware shutter key and a dial with another button.
