I wonder if it will ultimately be tablets, and not phones at all, that will be primarily redesigned in their best and most common form to be foldable.
Notes
- They would open up similar to a book with the screen only on the inside, but most importantly have a much larger single screen when flipped into portrait orientation like a tablet when opened.
- They would also fit in a much smaller space so that a tablet opened up to be about 9 inches, like an iPad mini, could fit in your pocket while being wider and shorter than a typical phone when closed.
- They would not have any screen on the outside to function like a phone, but would be designed more like a book or notebook, with the screen fully protected inside the device when closed.
