What use would any of these have on a phone that would compare in any way to the jump from flip phones to smart phones?

Have you not seen those Samsung videos?

The use of a folding screenw oudl be that you could have a tablet sized phone fold in half to be the size of a normal phone to fit in your pocket.

The use of a screen that rolls up woudl be so that you could have it roll into a pen like size and more easily again fit into a pocket or purse or something.

Here is a video from like 2013. https://www.youtube.com/watch?v=HRSGzfz6zwI 

Would those concepts not be cool?

Phones can already fit in your pockets.
