Isn't this going to be awesome?

Samsung Galaxy S4:

A Galaxy which is just 5 mm thick, Razor shop edges and on screen buttons.



Samsung Galaxy S5:

The first ever phone which expands phone display to become Tablet sized screen on the fly!!

Samsung Galaxy S6:

The first ever foldable display screen, which has multi-level folds. First fold can make it look like a phone and second fold makes it look like a Tablet.

Is all this possible?
