Over the last few years, new phones have had nothing to differ from competition. We saw more powerful cameras and bigger screens, but the basic design was a little touched. Over the past week, however, Samsung and Huawei have shown folding devices that can be expanded from pocket size to a larger, tablet-like screen. And companies such as Oppo and TCL also demonstrate their own concepts, though for the moment they are just prototypes. In terms of what you can buy soon, we took the incoming Galaxy Fold and Mate X and put them up against the only folding phone that made it on the market so far: Royole FlexPai. There are many more than those watering prices to look at below.
