iPhone Duo software restricts its already-small display

Reviewers criticized the iPhone Duo's software: a sidebar on the 5.4-inch cover screen takes up a significant chunk of the display. By contrast, the Galaxy Z Fold 8, with its taller and narrower body, is easier to use one-handed and makes better use of screen space.

• iPhone Duo's cover screen is 5.4 inches, and the sidebar eats into usable space
• Galaxy Z Fold 8 is easier to use one-handed thanks to its narrower body
• With gesture navigation on the Fold 8, almost no screen space goes unused
