iPhone Duo: Seven years late, but it’s kind of fine

Apple’s first foldable iPhone was always going to divide opinion. For people who have wanted a folding screen without giving up their iPhone, it is a welcome addition. For those already using an Android foldable, there is an obvious question: what took so long?

Samsung introduced the Galaxy Fold in 2019. Apple’s iPhone Duo arrives in 2026, entering a category that other manufacturers have spent years developing. There is plenty here that has been done before, but that does not mean there is nothing to get excited about.

The interesting part is what this format could change for iPhone users, and whether those changes justify the price.

We have been opening phones for years

The iPhone Duo opens like a book, with a 5.4-inch outer display and a 7.6-inch folding display inside. UK pre-orders start on 16 October, with availability from 23 October 2026.

The basic idea is familiar. Samsung’s original Galaxy Fold combined a smaller cover display with a larger flexible screen. It supported three apps at once and allowed users to continue using an app after unfolding the phone. Multitasking and moving between displays were part of the appeal from the beginning.

Microsoft took a different approach with Surface Duo. It had two separate displays joined by a hinge, giving users space for different apps and allowing them to drag content between compatible ones. Despite the shared name, that is physically different from the iPhone Duo’s continuous folding inner screen.

Apple has plenty of earlier examples to learn from. Its challenge is to make its own version useful enough to earn a place in people’s pockets.

Some of those new features might look familiar

Apple’s Duo Preview lets the person being photographed see a live preview on the outer display. Kid Cue plays animations to attract children’s attention towards the camera. Both give the second screen a practical purpose beyond showing notifications.

Google already offered Dual Screen Preview on its foldables. Its Pixel 9 Pro Fold, announced in August 2024, added Made You Look, which uses animations on the outer screen to catch a child’s attention during photographs. It also supported split-screen apps and dragging photos between them.

That helps explain why some Android users find the excitement excessive. They are watching familiar features being introduced to a different audience.

For iPhone owners, though, those features may still be a welcome change. Their value depends on how well they work and how often people use them.

What changes when the folding phone runs iOS?

The biggest change is having an iPhone interface designed for a device that opens, closes and works in different positions.

Apple’s Split View allows two apps to run side by side, including dragging a photograph into an email. The Duo can stand on its own for hands-free FaceTime calls, too. Apple has also announced support for Apple Pencil USB-C, although that is coming later this year.

If you regularly switch between a conversation and the information you are discussing, the appeal is easy to understand. You could check booking details while planning a trip or refer to a document while writing a reply, with less jumping between apps.

How useful that becomes will depend on the apps you use and how well they adapt. The extra space needs to make everyday tasks easier to justify carrying, and paying for, a folding phone.

Why people are excited

For an iPhone owner interested in foldables, the Duo removes one significant decision: whether a different screen is worth changing operating systems.

That is arguably its strongest appeal. People can want different hardware while being perfectly happy with their existing apps, habits and Apple services. The Duo gives them another option within a system they already use.

Early impressions have offered some encouragement. TechRadar’s hands-on account praised the display transitions and software experience, despite reservations about missing features. That is one reviewer’s assessment, but it suggests there may be more to the appeal than the novelty of a folding iPhone.

As of 15 September 2026, the Duo is still awaiting general release. A promising first impression cannot tell us how satisfying it will be after months of daily use.

£1,999 leaves plenty to question

The iPhone Duo starts at £1,999 for 256GB in the UK, rising to £3,199 for 2TB. At those prices, buyers have every reason to look closely at what they are getting.

The Duo uses Touch ID in its side button rather than Face ID. Its rear camera system includes a 48MP main camera and a 48MP ultra-wide camera, with 2x optical-quality zoom provided through the main sensor. There is no separate telephoto camera. It is also eSIM-only, so you cannot simply transfer a physical SIM from your old phone.

Some buyers may welcome fingerprint unlocking. Others may question spending that much on a phone without the camera arrangement they want. The folding display does not automatically make it the right upgrade for everyone.

Durability is another consideration. Apple specifies IP68 water and dust resistance under laboratory conditions, but that cannot establish how the folding screen and hinge will hold up over years of everyday use.

The jokes were inevitable

Arriving seven years after Samsung’s first Galaxy Fold makes Apple an easy target. Any suggestion of a breakthrough is going to be compared with what competitors have already released.

Samsung has already mocked Apple for revisiting familiar ideas, according to reporting on its social media response. It is an opportunity to remind people who got there earlier, although a competitor’s jokes tell us little about how good the Duo will be.

The fair criticism is that Apple should not receive credit for inventing features that other manufacturers have already shipped. But arriving later does not, by itself, make a product pointless either.

The price, the compromises and the familiar features all give people something to question. Whether those concerns outweigh the benefits will come down to what buyers want from their phone.

What this means for Apple

The Duo gives Apple a different reason to encourage upgrades. A folding display changes how someone can use their phone, and it could appeal to customers whose current iPhone already handles their everyday needs well.

It also gives people interested in foldables a reason to stay with Apple. Some may even find that a larger phone display covers tasks they previously reached for a small tablet to do, although that will depend on their needs.

Those are opportunities, rather than guaranteed outcomes. Apple still has to convince buyers that the extra screen is worth the cost and that its first attempt is dependable enough to keep.

The iPhone Duo does not need to be the first folding phone to matter. It needs to make people glad they bought one after the freshness has worn off.
