iPhone Duo’s small display hampered by software, while Galaxy Z Fold 8 offers smoother one-hand use
Early reviews note that iOS limits the iPhone Duo’s 5.4-inch screen with a sidebar, whereas Samsung’s Galaxy Z Fold 8 provides more usable space and easier one-hand navigation.
Early impressions of Apple’s iPhone Duo suggest that its software design restricts the utility of the device’s 5.4-inch display. Reviewers observed that the sidebar, positioned on the right side of the screen, leaves a substantial portion of the display unused, making single-hand operation more difficult than on competing foldables.
In contrast, Samsung’s Galaxy Z Fold 8, which features a taller and narrower outer screen, is reported to be more navigable with one hand. The device’s use of a navigation bar—or optional gesture controls—reduces wasted screen space, according to hands-on testing.
"The iPhone Duo feels harder to use with one hand because the dock sits on the right side, leaving a big chunk of the display unused," said Allison Johnson of The Verge.
"The Galaxy Z Fold 8’s taller, narrower profile makes the cover screen more easily navigable," a reviewer noted on X.
Apple’s approach aims to conserve space on a small display by stretching media vertically, but reviewers argue that Samsung’s design, which leaves more area for primary content, delivers a smoother user experience. The iPhone Duo is currently available in limited quantities, while the Galaxy Z Fold 8 continues to receive positive feedback.
