Apple’s first foldable iPhone Duo has made display-crease visibility one of the most closely watched details of its design. Samsung, meanwhile, has had several generations to refine the folding screen on its Galaxy Z Fold series. A new side-by-side comparison gives an early look at how the iPhone Duo and Galaxy Z Fold8 handle one of the biggest visual challenges of foldable phones.
The comparison is particularly interesting because neither company is simply trying to make the physical fold disappear. Instead, Apple and Samsung are using different combinations of display materials, structural support and reflection control to make the crease less distracting during everyday use.
iPhone Duo and Galaxy Z Fold8 Look Similar Head-On
A short comparison video from technology journalist Joanna Stern provides a useful visual test of the two foldables.
When both displays are viewed directly from the front, the center fold on the iPhone Duo is difficult to distinguish. The Galaxy Z Fold8 also looks relatively smooth from a straight-on viewing angle.
The difference becomes easier to notice when the phones are tilted toward a light source. Reflections running across the center of the flexible panels can reveal the fold more clearly, showing that crease visibility depends heavily on lighting and viewing angle.
This is an important distinction. A phone can have a physically noticeable folding area while still appearing almost flat during normal viewing. Conversely, a strong reflection can make a relatively subtle crease appear much more obvious in a photograph or video.
Why the iPhone Duo’s Crease Can Be Difficult to See
Apple has placed considerable emphasis on the appearance of the iPhone Duo’s inner display.
The 7.6-inch folding screen uses a nano-texture treatment designed to reduce glare and control reflections. That matters because reflected light is one of the main reasons a fold becomes easier to see.
When the display is viewed under bright indoor lighting or near a window, the surface can reflect surrounding objects and light sources. A surface treatment that reduces those reflections can therefore make the central fold appear less prominent.
However, it is important not to confuse reduced crease visibility with a completely crease-free display.
The iPhone Duo still uses a flexible panel that repeatedly bends around a hinge. The nano-texture surface can influence how the fold looks to the eye, but it does not remove the underlying mechanical challenge of repeatedly folding a large OLED panel.
Galaxy Z Fold8 Uses Both Structure and Reflection Control
Samsung approaches the problem somewhat differently with the Galaxy Z Fold8. Foldable display technology continues to evolve rapidly, with manufacturers experimenting with new hinge designs, screen materials, and display structures to make foldable phones thinner, more durable, and less noticeable when unfolded.
The Fold8 uses a reinforced internal structure that includes titanium components around the folding display. This construction is intended to provide support to the flexible panel while maintaining the thin profile expected from a modern foldable phone.
Samsung also uses an anti-reflective treatment on the main display.
That combination is significant because the crease has two different aspects: the physical deformation of the flexible panel and the way light reflects from that deformation.
The structural layer addresses the first problem, while the anti-reflective surface helps with the second.
As a result, Samsung’s strategy is not simply about hiding the crease. It is about controlling both the physical support of the folding panel and how visible that fold becomes under different lighting conditions.
iPhone Duo vs Galaxy Z Fold8: Crease Comparison
| Feature | iPhone Duo | Galaxy Z Fold8 |
|---|---|---|
| Foldable design | Book-style foldable | Book-style foldable |
| Inner display | 7.6-inch folding display | 7.6-inch folding display |
| Crease visibility | Very subtle when viewed straight on | Relatively subtle when viewed straight on |
| Surface approach | Nano-texture treatment | Anti-reflective treatment |
| Structural approach | Engineered folding display and hinge system | Reinforced structure with titanium components |
| Reflections | Reduced through surface treatment | Reduced through anti-reflective display |
| Main difference | Strong emphasis on minimizing visible glare and fold | Combines structural reinforcement with reflection control |
The table highlights why a simple “which phone has no crease?” comparison can be misleading.
Neither device should be judged solely from one photograph. Lighting, viewing angle, screen brightness and the content displayed on the panel can all change how prominent the fold appears.
Is the iPhone Duo Actually Creaseless?
The answer is more complicated than the marketing impression may suggest.
From a normal straight-on viewing position, the iPhone Duo’s center fold can be extremely difficult to notice. That gives Apple a strong advantage in perceived display smoothness.
But the crease can become more apparent when light hits the screen at an angle.
This is also true of the Galaxy Z Fold8. A reflection traveling across the fold can make the center of the screen easier to identify even when the display looks nearly flat from directly in front.
Therefore, it is more accurate to describe the iPhone Duo as having a less visually obvious crease rather than claiming that Apple has completely eliminated the physical fold.
That distinction will become even more important after long-term use, when repeated folding cycles provide a better indication of how each display ages.
The Real Difference May Appear in Everyday Lighting
For most users, the more useful question is not whether either phone has a mathematically perfect flat screen.
Instead, the question is:
How often will you actually notice the crease while using the phone?
This depends heavily on the environment.
Under soft indoor lighting, both displays can look remarkably clean. Outdoors or near strong light sources, reflections can expose the folding area more clearly.
The iPhone Duo’s nano-texture approach could give it an advantage in situations where glare is the main reason the crease becomes noticeable. Samsung’s anti-reflective technology serves a similar purpose, while its reinforced internal structure focuses on supporting the folding panel itself.
This means the two companies are solving related problems from slightly different directions.
What the Early Comparison Does Not Tell Us
A short video can demonstrate visual crease visibility, but it cannot establish long-term durability.
It does not show how either display will look after thousands of folding cycles, how the hinge will age, or whether the appearance of the crease changes after months of daily use.
That is particularly important for the iPhone Duo because it represents Apple’s first generation of foldable iPhone hardware.
Samsung has considerably more experience with foldable phones, giving the Galaxy Z Fold8 the benefit of multiple generations of hinge and display development.
A proper long-term comparison will therefore need to examine more than the appearance of the crease on a brand-new device.
iPhone Duo vs Galaxy Z Fold8: Early Verdict
The early comparison suggests that both Apple and Samsung have made substantial progress in reducing the visual impact of the fold.
The iPhone Duo appears particularly impressive when viewed straight on, where its central crease can be difficult to distinguish. Its nano-texture display also gives Apple another way to control reflections that can draw attention to the fold.
The Galaxy Z Fold8 takes a more established approach by combining structural reinforcement with an anti-reflective display surface. Its crease can still become visible at certain angles, but Samsung’s design shows how far the company’s foldable technology has evolved.
For now, the most accurate conclusion is not that one phone has completely eliminated the crease. Instead, both devices are becoming better at making the crease less noticeable during normal use.
The iPhone Duo may have the visual advantage in some lighting conditions, but a longer hands-on test will be needed to determine whether that advantage remains after extended daily folding.
For buyers choosing between Apple’s first foldable iPhone and Samsung’s latest Galaxy Z Fold, the crease is therefore only one part of the decision. Display quality, hinge durability, software, camera performance, battery life and overall device thickness will ultimately matter just as much.
