Apple entered the foldable smartphone market with the iPhone Duo, bringing a new display. The foldable category was led by Samsung for years. While the iPhone Duo and Samsung Galaxy Z Fold 8 share similarly sized inner screens, their display designs take different paths.
The iPhone Duo features a 7.6-inch Super Retina XDR OLED inner display and a 5.4-inch outer screen. Both displays support ProMotion and can reach up to 3,000 nits of peak brightness. The inner screen also uses an under-display FaceTime camera, allowing Apple to avoid a visible camera cutout in the middle of the large panel.
Samsung’s Galaxy Z Fold 8 also features a 7.6-inch internal display. However, its cover screen measures around 5.5 inches and uses a taller 16:10 format. The inner display follows a 4:3 ratio. Samsung aims for a more traditional book-style foldable experience, with a major change in screen proportions when the phone opens.
The biggest display talking point on the iPhone Duo is its crease treatment. Apple uses a custom nano-texture finish and optically clear adhesives. This allows the display layers to move as the device folds. The tech giant claimed that this reduces stress and minimises crease visibility.
The iPhone Duo does not reinvent the foldable display. Apple focused on refining the experience. A flatter-looking inner panel, reduced crease visibility and a consistent screen shape are central to that strategy.
Samsung still masters the foldable experience behind the Galaxy Z Fold 8. Apple, meanwhile, is betting on hardware and software integration that can make its first foldable feel more premium than its competitors.
