iPhone Duo review: Apple's foldable hides the crease

Apple's first foldable, the iPhone Duo, stands out for a screen with no visible crease, tackling the biggest complaint about foldables, a review finds. It weighs the same as the iPhone 18 Pro Max but is 25% heavier than Samsung's Galaxy Fold 8, which is noticeable when opening it one-handed. The design and hinge feel sturdier than other first-generation foldables.
