Recent iPhone Fold leaks suggest Apple may take a very different approach from rivals like Samsung and Google. Instead of a tall phone that unfolds into a larger display, rumors point to a short, wide device that unfolds into something closer to an iPad mini.
3D-printed mockups based on these leaks reinforce the idea that the iPhone Fold could be more like an iPad you fold into your pocket, rather than an iPhone that simply opens up. While the final design may change, such a form factor would push iOS in a new direction and require major interface adaptations.
