Hands-On With the iPhone Duo: The Crease is Still There, But Barely

How Does the Crease Compare to Previous Models

Apple unveiled the i Phone Duo at its September 9, 2026 event in Cupertino, inviting select media to test the device immediately afterward. The foldable smartphone features a dual-screen design that unfolds into a tablet-sized display, marking Apple’s first entry into the foldable market. Journalists were given brief hands-on time to assess build quality, screen performance, and usability.

Initial impressions confirm that while the visible crease along the hinge remains present, it is significantly less noticeable than in earlier prototypes or competing devices. Apple appears to have refined the hinge mechanism and layering of materials to minimize the indentation, though it can still be detected under certain lighting or when touched directly. The device feels solid when closed, with a seamless transition between the two halves when opened.

Can Users Really Ignore the Fold Line

Testers noted that the crease on the i Phone Duo is far shallower than on the first-generation foldables from other manufacturers, with one describing it as „almost imperceptible during normal use.” The display maintains consistent brightness and color accuracy across the fold line, with no visible distortion or dead pixels reported during testing. Apple has not disclosed the exact materials used in the hinge, but experts suggest a combination of ultra-thin glass and a new polymer layer contributes to the improved feel.

While the crease is minimal, it is not entirely gone. Some testers reported being able to feel it with a fingernail when pressing firmly along the center of the screen. However, during typical interactions like scrolling, typing, or watching video, the fold line did not interfere with touch responsiveness or visual experience. Apple’s software appears to compensate for the hinge area, adjusting touch sensitivity and UI elements to avoid placing critical controls directly over the crease.

Is the crease completely gone on the i Phone Duo? No, the crease is still present but greatly reduced in depth and visibility compared to earlier foldable devices, making it barely noticeable during everyday use.

Frequently Asked Questions

Does the fold affect screen durability or performance? Apple has not released durability test results, but during hands-on sessions, the screen showed no signs of damage, lag, or display anomalies across the hinge area after repeated opening and closing.

Will the crease worsen over time with regular use? There is no data yet on long-term wear, but Apple claims the hinge is rated for hundreds of thousands of folds, suggesting confidence in its longevity under normal conditions.
