Apple's iPhone Duo Survey Asks Buyers About the Crease, Display Size and Under-Display Camera

Apple has started emailing surveys to some iPhone Duo buyers, asking for feedback on the display size, the crease, the under-display camera and other features, according to MacRumors. It matters because the Duo is Apple's first foldable, and as of the November 5, 2026 report it had been on sale for only about two weeks. The questions give a rare peek at what Apple is checking first.

What's just as interesting is what the survey leaves out. A few of the Duo's most talked-about complaints don't appear in it at all, and that's worth knowing if you own one or are thinking about buying.

What Apple's iPhone Duo survey asks buyers

The first question asks why you bought the iPhone Duo now. The answer options include "I wanted to try Apple's first foldable," "It was an impulse purchase," and "I expect smartphone prices to increase." So Apple wants to know whether buyers came for the novelty, acted on a whim or were thinking about costs down the road.

After that, the survey moves to the hardware. It asks about the size of the display when the phone is closed, how visible the crease is, whether the under-display camera is distracting, and how good that camera's images look. The final question is open-ended: what would you add or change about the iPhone Duo? MacRumors notes that it isn't unusual for Apple to run surveys after a new product debuts, so this fits a familiar pattern.

Crease and display size: what the questions focus on

Two of the questions deal with how the Duo looks and feels in the hand. One covers the size of the closed display, the other how visible the crease is. The Duo's outer display measures 5.4 inches, which MacRumors says is about the same as the discontinued iPhone mini line, so the closed size is a natural thing to ask about.

The source doesn't say why Apple is running the survey or what it plans to do with the answers, so it's best not to read too much into it. What the questions do show is the list of topics Apple considers worth asking about on a first-generation foldable. If you've used the Duo, the crease and the compact outer screen are exactly the things you'd expect to have an opinion on.

Moving your data to a new phone or foldable

Whether you jumped on the Duo at launch or you're still deciding, a new phone usually means moving a lot of stuff. Photos, videos, contacts and messages all need to come across, and old devices tend to be full of duplicates and forgotten downloads. A good data transfer app makes that part less painful, and it's worth sorting out before you switch rather than after.

Smart Transfer is one option. Its Clone tool moves pictures, videos, contacts, messages, apps and more between Android and iOS devices over Wi-Fi, so Data transfer doesn't mean starting from scratch, and the same app covers File Transfer and Sms Transfer type jobs when you share things or bring messages over. Its Storage tools can help you Free up storage by grouping duplicates, similar and blurred images, screenshots, downloads and WhatsApp media into folders. Used that way, it works as a data organiser app as well as a data transfer app, and a tidy library makes any move to a new device simpler.

How the 4MP under-display camera fits into the feedback

The camera gets two questions of its own: whether the under-display camera is distracting, and what the image quality is like. That's a sensible focus. The inner display's under-screen camera is limited to 4MP, and MacRumors says it was one of the main complaints in reviews.

So here the survey and the reviews line up. Apple is asking directly about something reviewers already flagged, which is the kind of overlap you'd hope for in a feedback form. If you own a Duo and the camera bothers you, or doesn't, this is where your answer counts.

Complaints the survey leaves out: Touch ID, unoptimized apps and hinge cracks

According to MacRumors, the survey doesn't ask about Touch ID, about using apps that aren't optimized for the Duo, or about the display cracks some owners have reported. MacRumors describes all three as top complaints alongside the camera. The App Store does show screenshots of Apple's built-in apps running on the Duo, many in landscape, but the survey itself doesn't touch on how third-party apps behave.

The cracks deserve a careful read. Some owners have shared photos on Reddit and the MacRumors forums showing damage along the hinge, and most show a line of bright pixels across one side of the screen. Almost all the reported faults sit right along the hinge. These are user-shared photos, though, and the source doesn't establish how common the problem is, so there's no basis for saying it affects a lot of devices.

What the survey means for early foldable buyers

If the email lands in your inbox, the last question is your chance to say anything the earlier ones missed. Since Touch ID, unoptimized apps and hinge damage aren't covered by the multiple-choice questions, the open-ended box looks like the natural place to mention them if they affect you. That's a suggestion, not something Apple has said about how it reads the answers.

If you're still on the fence, treat the survey as a checklist of things to look at yourself: how the closed display feels at 5.4 inches, how visible the crease is to you, and whether a 4MP under-display camera is good enough. Also keep an eye on the hinge area and on reports from other owners, since this is a first-generation device and the picture is still forming.

Apple's survey shows it is asking about the crease, the closed display and the camera, while Touch ID, unoptimized apps and hinge cracks stay off the form. If you own a Duo, the open-ended question is where those can go.
