iPhone Duo vs Samsung Galaxy Z Fold8 Ultra - Design

From the outset, the two foldables are constructed in the same broad manner. Both are book-style foldables, opening to reveal a tablet-sized inner screen. To save users from having to open the devices every time they want to use it, there's a smaller secondary screen on the outside. This gives users the best of both smartphone and tablet worlds. In terms of size, the iPhone Duo is a little shorter but wider overall, at 6.48 by 4.64 inches when unfolded, and 3.31 by 4.64 when folded up. The Fold8 Ultra is taller at 6.24 inches, but the width varies between 5.64 inches when opened to 2.87 inches when folded.
