Apple's iPhone Duo Is Samsung's Old Roadmap — and That's the Point

What Samsung Dropped, Apple Picked Up

The most striking detail from ITmedia’s hands-on with the iPhone Duo isn’t hidden in a spec sheet. It’s in the fact that Apple appears to have reverse-engineered Samsung’s foldable mistakes — or rather, its retreats.

Samsung pioneered the foldable phone. Then it quietly walked away from two features it once championed: under-display cameras and reliable flex mode. The iPhone Duo, reviewed in Japan shortly after Apple’s September 9 event, includes both — and that reversal tells you more about Apple’s foldable philosophy than any press release could.

Samsung dropped its under-display camera on the Galaxy Z Fold 5 after judging the image quality unacceptable at the thickness it was willing to accept. Apple, according to the ITmedia hands-on, kept it anyway. The company hasn’t disclosed the camera’s resolution — a classic Apple silence on specs that usually signals either confidence or calculation. Either way, the reviewer who tested it directly found no objectionable drop in quality compared to a standard punch-hole camera.

The flex mode story is even more revealing. The reviewer noted they had been using a Galaxy Z Fold 8 as a comparator since August and initially thought flex mode was unnecessary. After a few days with the Duo, they changed their mind. The ability to prop the phone at half-open on a table — for video calls, for clock display while sleeping, for tent-mode media viewing — turned out to be a genuine utility shift, not a gimmick.

The Hardware: Restraint as Strategy

The Duo closes to a 5.4-inch form factor and opens to 7.6 inches. At 254 grams it feels heftier when folded, but the compact surface area makes it surprisingly pocketable. Open thickness is a slim 5.2 millimeters; folded, it measures 11.3 millimeters — noticeably thicker than a conventional flagship, but nowhere near the clunky profiles of early foldables.

The camera array is a 48-megapixel wide plus an ultrawide. No telephoto. Apple is again making a choice that reads like restraint to some and cost-cutting to others. In practice, the absence of a telephoto lens is less punishing on a device this large, where digital zoom and computational photography bridge much of the gap.

What’s genuinely novel is the nano-texture display finish. Most foldable discussions fixate on the crease — the visible ridge where the screen bends. The nano-texture diffuses reflections in a way that makes the crease nearly disappear when the display is lit. You cannot see the screen off in a hands-on environment, so the real-world verdict depends on whether that flatness holds in direct sunlight or dark rooms. Apple’s track record with nano-texture on iPad Pro suggests it will.

The Software: Where Apple Actually Wins

Hardware parity with Samsung is notable. Software execution is where the Duo diverges fundamentally.

The reviewed behavior is deceptively simple: open the phone halfway, and content on the outer display continues seamlessly onto the inner display. Close it partially, and the app reflows intelligently — Netflix, for example, can split the screen with controls on one half and video on the other, or anchor itself to the outer display in tent mode while the inner screen stays idle.

This is not magic. It is the same vertical integration advantage Apple has always held: hardware, OS, and apps all built by the same company. Samsung can do some of this now with its own apps, but the broader Android app ecosystem is not uniformly designed for multi-form-factor continuity. Apple’s first-party apps are; third-party adoption is slower but inevitable given the install base.

Split-screen multitasking on the Duo required no instructions. The reviewer — who had spent weeks with the Z Fold 8 — found the gesture intuitive within seconds. That continuity from flat to folded interaction is the experience Apple has marketed for a decade. The Duo simply extends it into a new dimension.

The Price: ¥360,000 and What It Means

At roughly ¥360,000, the iPhone Duo lands in a bracket that is brutally exclusive by Japanese standards. For context, the average annual salary in Japan is approximately ¥4.5 million. This phone costs nearly 8% of that — more than a mid-range car payment for many households.

The price is not accidental. It positions the Duo as a status object first and a utility device second. Apple has always priced itself this way. What’s different is that foldable phones historically struggled to justify premium pricing because the technology felt experimental. Apple’s version — with its refined hinge, invisible camera, and app-level continuity — removes the experimental label. It reframes the foldable as mature.

That framing matters globally. In markets where foldables are still seen as novelty items with compromised durability, Apple’s launch forces a reckoning: if a $1,000-plus foldable can do everything a $400 one does and look better doing it, the value proposition of cheaper alternatives collapses.

Who Loses

Samsung loses the most immediate narrative battle. The Z Fold 8 is a solid device, but the Duo’s flex mode and under-display camera reopen a gap Samsung thought it had closed — and then some. Samsung’s next move will be critical. If it accelerates its own under-display camera rollout, it risks repeating the quality misstep that forced its earlier retreat. If it holds back, it concedes the feature lead to a company that never claimed to lead in foldables.

Chinese foldable makers — Huawei, Honor, Xiaomi — occupy a middle ground they now struggle to fill. Their devices are cheaper and often more ambitious on paper, but they lack Apple’s software continuity and brand gravity. In Japan especially, where Apple’s installed base is enormous and Samsung’s foldable presence is well-established, the Duo’s arrival may compress demand for both.

What Happens Next

The real test for the iPhone Duo will come in six to nine months, when early adopter enthusiasm fades and reviewers begin comparing long-term hinge durability, battery degradation, and app compatibility across the full fold/unfold cycle. Apple’s first foldable carries the weight of its entire brand — any widespread failure will reverberate far more than a Galaxy Z Fold malfunction would.

Japan’s hands-on previews suggest Apple got the fundamentals right: the hinge feels solid, the software handles the transition gracefully, and the camera choices reflect a deliberate product philosophy rather than a spec sheet arms race. The question now is whether that philosophy scales to the millions of buyers Apple needs to move to justify the device’s existence.

One thing is clear: Apple did not enter the foldable market to compete on price or on raw innovation theater. It entered by doing what it does best — taking features the market had already vetted, removing the compromises that made them frustrating, and charging a premium for the result. The iPhone Duo is not trying to reinvent the foldable phone. It is trying to make the reinvention unnecessary.
