Apple’s First Foldable Is Finally Here
The iPhone Duo arrived at Apple’s fall 2026 event alongside the iPhone 18 Pro. Closed, its 5.4-inch cover screen fits one hand; opened, it becomes a 7.6-inch display — a mini tablet in your pocket.
⚠️ Price and release date aren’t confirmed by Apple yet. Check Apple’s website for updates. Price aside, the real question is whether it’s worth it.

Early Hands-On Impressions
The crease: flatter than expected, still there
Early media and creator impressions agree: the center crease is strikingly flat. A fingertip barely feels it, and touch input is unaffected. Apple’s nano-texture cuts reflections, hiding the line from most angles.
Opinions still vary — some say they can’t feel it at all, others notice a faint trace. Try it in a store.
Opening and closing: the animation steals the show
Hands-on reviews praised the smooth unfold transition — the display grows from 5.4 to 7.6 inches with real elegance. The hinge packs over 100 tiny parts, feels solid, and carries an IP68 rating.
Multitasking: split view, but fixed
iOS 27 brings split-screen — two apps side by side, even two Safari tabs. The split is locked to 50/50, though, with no resizing. You can save app pairs to reopen together.
Apple Pencil support
The Duo supports Apple Pencil (USB-C) on both screens — handwriting and note-taking. A real ecosystem edge over rival foldables, opening later in 2026.
The Three Trade-offs
1. No Face ID — welcome back, Touch ID
To fit the hinge, Apple swapped Face ID for side-mounted Touch ID. A big adjustment for long-time iPhone users.
2. Two cameras, no telephoto
Main + ultra-wide only — no periscope, no variable aperture like the 18 Pro. If photo/video matters most, the Duo will feel like a step down.
3. 254 g — a heavy foldable
All that folding hardware adds up; at 254 g it’s among the heaviest mainstream foldables, about 53 g more than the Galaxy Z Fold8 (201 g). One-handed use gets tiring, and at 11.3mm folded, you need deep pockets.
Duo or iPhone 18 Pro?
| Priority | Pick |
|---|---|
| Photography, video, variable aperture | iPhone 18 Pro |
| Big-screen multitasking, long reads | iPhone Duo |
| Frequent travel, physical SIM | Note: Duo is eSIM-only |
| Best value overall | iPhone 18 Pro Max |
Bottom Line
The first-generation Duo is more polished than expected — hinge feel and display quality exceed predictions. But Apple is clearly testing the waters: two colors, no Face ID, cameras below the Pro tier, and a premium price.
- Apple loyalists who want the first foldable: go ahead, but wait for the October launch and real-world verdicts.
- Curious but not screen-hungry: wait for the next generation — Face ID, a third camera, and more colors may return.
- Serious shooters: skip the Duo; buy the iPhone 18 Pro series.
Apple staged its fall launches in two waves — flagships first, standard models later. The Duo is a bold experiment: tempting if you’ve got deep pockets and love new toys; the smarter play for most is waiting for a more complete, refined second act.
Availability: Taiwan pre-orders open October 16 at 8:00 p.m., sales from October 23.
