September 10, 2026 — The first hands-on impressions of Apple's foldable iPhone Duo are in, and the early verdict is surprisingly consistent: Apple may have solved the crease problem better than anyone expected — but it made a compromise that photography enthusiasts won't love .

Following the September 9 event, tech reviewers and YouTubers were given brief hands-on time with the device at Apple Park. Their first impressions, shared across social media and video platforms, paint a nuanced picture of Apple's first foldable .

The Crease Debate: Almost Flat, But Not Gone

The foldable crease has been the most scrutinized aspect of every foldable phone ever made. For the iPhone Duo, the early hands-on reports are mixed — but mostly positive .

The Positive Reviews

YouTuber "壹加壹" member Lean shared his impressions on Instagram, saying the fold "is actually very flat — when you touch it, it's just a tiny feeling, very shallow, very beautiful." He added that it "almost doesn't affect the touch experience at all" .

The key to this achievement, according to 36Kr's in-depth analysis, is that Apple took a different approach than other manufacturers. Rather than thickening the UTG (Ultra Thin Glass) or adding hinge filler — the "traditional route" — Apple applied the nano-texture glass from its flagship Studio Display XDR to the inner screen .

The Not-So-Positive Reviews

Not everyone was convinced. Notebookcheck reported that "in hands-on videos emerging from Apple Park, the iPhone Duo's crease is quite clearly visible from certain angles." The publication noted that "real-life usage will definitely have its impact, making the crease more visible as the device accumulates more fold cycles" .

Chinese tech reviewer "李大锤同学" shared footage showing a "relatively obvious crease" when the screen is unfolded, and said that touching the fold area "you can still feel some crease," though it wasn't obvious .

The Design: A Smart New Approach to a Wider iOS

Beyond the crease, reviewers were impressed by how Apple adapted iOS to the foldable form factor .

The most praised design decision: moving the Dock, app toolbars, and status icons to the right side of the screen when unfolded. This vertical arrangement maximizes the usable horizontal space in the wide-screen mode — something no other manufacturer has attempted .

Lean described it as "a very smart layout" and noted that the gesture controls feel more natural with the Dock on the side .

Other design highlights from hands-on reports:

• Single-hand unfold: The device can be opened with one hand
• Touch ID position: The side-mounted fingerprint sensor is "well-designed" and easy to reach
• Matte screen finish: The nano-texture glass gives the display a premium, anti-glare feel
• Camera preview: When unfolded, the front screen can show the photographer's view in real-time, or play animations to attract children's attention

The iPhone Duo features a 5.4-inch outer display and a 7.6-inch inner display with a resolution of 2670×1878 (430 PPI) . The inner screen supports 1-120Hz ProMotion, always-on display, and 3000 nits peak brightness. Notably, Apple included an under-display FaceTime camera on the inner screen — a rare feat that Samsung has abandoned .

The One Regret: No Telephoto, No Variable Aperture

If there's one consistent criticism across all hands-on reports, it's the camera system .

The iPhone Duo has two rear cameras: a 48MP Fusion Main (26mm, f/1.6) and a 48MP Fusion Ultra Wide (13mm, f/2.2). Both are capable sensors — the Ultra Wide is identical to the one on the iPhone 18 Pro .

But the Duo lacks two features that define the iPhone 18 Pro's camera system:

Engadget put it bluntly: "The lack of a dedicated telephoto lens won't be a good fit for concertgoers, nature photographers or anyone else used to the powerful zoom performance of Pro-series iPhones."

Lean echoed this sentiment, calling the camera the "only regrettable part" of the Duo — no telephoto, no variable aperture .
