Apple's foldable iPhone Duo hides the crease, but is heavier

Apple's first foldable, the iPhone Duo, stands out for having no visible crease on its folding screen, according to a week-long review. The passport-size phone weighs the same as the iPhone 18 Pro Max but is about 25% heavier than Samsung's Galaxy Fold 8, which reviewers noticed when opening and closing it, often with one hand.
