iPhone Duo selfie cameras: outer, under-display and rear

The iPhone Duo has two front cameras: a 12MP Center Stage camera in the 5.4-inch outer display and an under-display FaceTime camera beneath the 7.6-inch inner display. Reviewers mostly agree: the outer camera handles everyday selfies, the under-display camera is for calls, and the sharpest selfies come from the rear cameras.

More on the rear cameras in the iPhone Duo camera review.

What Apple's spec page says

Apple's iPhone Duo spec page lists the outer camera at 12MP with an f/2.2 aperture, Retina Flash, Night mode, Portrait mode with Focus and Depth Control, Photographic Styles and Smart HDR 5. It records 4K Dolby Vision video at up to 60 fps, Cinematic mode at up to 4K and 30 fps, and 1080p slow motion at 120 fps.

The under-display FaceTime camera gets a wider f/1.8 aperture, 1080p video at 30 or 60 fps, Center Stage for video calls and ultra-stabilized video. Apple's spec page gives no megapixel figure for it, and MacRumors noted in September that Apple hadn't revealed the resolution.

Apple's launch announcement says the inner camera "stays hidden when not in use to keep the screen uninterrupted."

The outer camera is the one reviewers point to for selfies

Gizmodo's Raymond Wong wrote in his iPhone Duo review that selfies from the outer camera look decent, and liked that its square sensor shoots horizontal or vertical selfies in either hold.

Macworld's Jason Cross, in his iPhone Duo review, called it a much better camera than the inner one, but compared the 12MP sensor to the one in the iPhone 17e or earlier. MacRumors points out that the iPhone 17 and iPhone 18 Pro use an 18MP front camera, so the iPhone Duo's 12MP outer camera is a step down from those models. The screen around that camera has its own outer display review.

The under-display camera is mostly hidden, and clearly softer

It's the first under-display camera on an iPhone, according to MacRumors, and reviewers split on how invisible it is. Gizmodo said it shows as a black hole-punch when a camera app is open and otherwise blends in, if a little pixelated.

Macworld described a small circle without the anti-reflective nano-texture that's easy to spot but soon stops registering. MobileSyrup's Dean Daley was less forgiving in his column: "you can pretty much always see the UDC." More on that coating in the nano-texture layer explainer.

On image quality, the verdicts are harsher. Marques Brownlee called its photos "trash," as MacRumors reported (see the MKBHD review summary). Gizmodo found photos "low-res, washed out, and just not sharp at all," and Macworld cited weak dynamic range and over-processing artifacts.

Macworld and Gizmodo both describe it as 4MP. Apple hasn't published that figure.

For calls, its stated job, reviewers were kinder. Gizmodo called FaceTime video muddy but serviceable, Macworld said the compressed, low-resolution stream of a video call lets it do an okay job, and MobileSyrup judged it adequate for FaceTime. Joanna Stern found it fine for FaceTime in good light and bad elsewhere (see the Joanna Stern review summary).

Edge Light could help in dim rooms. Apple lists it for under-display video calls, and MacRumors reports that it arrived in iOS 27.2 and lights the edges of the screen to brighten your face in FaceTime and apps such as Zoom. It works only when the iPhone Duo is unfolded, and you turn it on from video effects in Control Center during a call (see the iOS 27.2 guide).

Rear-camera selfies are the real selfie camera

Apple says you can take a selfie with the higher-resolution rear cameras, the 48MP Fusion Main and Fusion Ultra Wide, and preview it on the outer display.

MacRumors' how-to lays out the steps: unfold the iPhone Duo, open Camera, turn the phone around and drag the Show Camera slider on the outer display, then frame and shoot from there. It works only while the phone is open.

Macworld's Cross said this gives "better selfie quality than any iPhone ever before." The trade-off, on paper, is holding a 254 g phone open and backwards.

Two screens add a few camera tricks

Apple describes several features built on the outer display. Duo Preview shows the live preview there so subjects can check their framing, Smart Take captures automatically when subjects are posing, and Kid Cue plays Peanuts animations to get children to look at the camera.

Apple's Pose iPhone Duo guide describes folding the phone like a tent so the outer display faces the person you're photographing. More in tent and laptop modes.

On calls, Duo FaceTime lets someone join using the outer display and camera, and Dual Capture shares front and rear camera feeds at once. MacRumors reports that iOS 27.2 brought Dual Capture to Group FaceTime calls.

Macworld said Smart Take should come to every iPhone, though The Verge found that camera features using both displays, and Smart Take, got hot and lagged (see The Verge review summary).

Bottom line: who should care

For casual selfies, the outer camera covers the basics on paper, and the rear-camera trick gives the best results reviewers saw, if you unfold the phone.

For frequent video calls with the phone open, expect softer, muddier video than an iPhone front camera usually gives, per Gizmodo and Macworld, and Joanna Stern found it bad outside good light. If a sharp front camera matters most, the iPhone 18 Pro comparison is worth reading first.

We think the under-display camera is the most clearly first-generation part of the iPhone Duo's camera system. More verdicts are in the launch reviews roundup. How often do you actually use the inner camera?
