Apple’s first foldable iPhone is here. Your applications need to be ready for a screen that opens, closes, and runs two apps side by side.
Perfecto has a long record of supporting new Apple releases, and the iPhone Duo continues it. In this post, you’ll learn what the iPhone Duo means for your testing strategy, how Perfecto helps your team test on it, and how Perforce Autonomous Testing keeps your tests working as devices change.

What Is the iPhone Duo?
The iPhone Duo is Apple’s first foldable iPhone, announced on September 9, 2026. Closed, it has a 5.4-inch outer display. Open it, and you get a 7.6-inch inner display, the largest screen Apple has put on an iPhone. It runs on Apple’s A20 Pro chip with iOS 27, and Apple says it supports Split View, so people can use two apps side by side.
For QA and development teams, a foldable adds a new test surface: a screen that changes size in the user’s hands. Layouts need to adjust when the phone opens or closes. Apps need to hold up when they share the screen with another app. Each of those changes is a new path to test before your customers find a problem for you.

Perfecto commits to support for customers on all new releases. It even offers beta support, so teams can prep their apps before a release lands. With the iPhone Duo, that track record now covers Apple’s first foldable.

Perfecto’s cloud device lab gives your team real devices, simulators, and emulators. You can test on the newest hardware and operating systems without buying and managing every device yourself. Here’s what that means in practice:
- Real-device access to the latest iPhone models and iOS versions
- Parallel testing across devices, browsers, and operating systems
- Cross-platform coverage for web, mobile, and desktop
- Faster feedback so defects show up early, not in production
How to Test Apps on the iPhone Duo
A foldable changes how people use your app, so your test plan should change too. Start with the situations your users will hit most often.
| What to test | What to look for | Why it matters |
| Opening and closing the phone | The app keeps its state, resizes cleanly, and doesn’t lose user input | People will fold and unfold the phone mid-task |
| Outer and inner displays | Content and navigation fit both the 5.4-inch and 7.6-inch screens | One app now has to look right on two screen sizes |
| Split View and dual-app use | The app works when it shares the screen with another app | Users will run two apps side by side |
| Camera features | Camera flows work with the outer display’s live camera preview for subjects | The Duo adds new ways to use the camera |
| Core user journeys | Login, checkout, payments, and other key flows work from start to finish | These flows drive revenue and trust |
Start now. Test against the new form factor right away, then keep checking as iOS updates arrive. The teams that handle new devices best treat readiness as an ongoing practice, not a last-minute sprint.
Back to topHow Perfecto AI Helps You Prepare for the iPhone Duo
A new form factor puts pressure on testing teams. You need to validate quickly, cover more scenarios, and do it without adding weeks of manual work. Perfecto AI is built for that kind of shift.
With Perfecto AI, you describe what you want to test in plain language, and Perfecto designs, runs, and maintains the test for you. There are no locators or scripts to manage. Because the AI adapts to changes in your app, your tests can keep running as your team updates layouts for a new screen size.
Autonomous Testing in Action: Functional, Performance, and Mobile Testing from a Single Prompt
Perfecto AI's prompt-based tests include visual and semantic validation, which helps them adapt as your app changes. That cuts down on the false positives that stall releases.
If your team still uses scripts, you don't have to start over. Perfecto integrates with existing frameworks and tools, so you can blend AI-driven testing with the workflows you already have. AI-driven reporting and analytics give every team member quick access to results, so your team can find and fix issues faster.

Any major device launch brings the same set of challenges:
- Inadequate test coverage that leaves new behaviors unchecked
- Overreliance on manual testing instead of scalable automation
- Late defect detection that pushes bugs into production
- Slow feedback loops that delay release decisions
Large organizations feel this most. Banks, healthcare providers, telecom companies, and retailers all deliver essential services through their apps. For these teams, a smooth experience on day one is a must. A single broken flow can affect thousands of customers within hours of a new device hitting the market.
