Does the iPhone X support dual camera recording?
No. iPhone X shipped in November 2017 with Apple’s A11 Bionic chip, one full generation before A12 Bionic — the exact chip Apple documents as the floor for AVCaptureMultiCamSession, the framework simultaneous front-and-back capture is built on. iPhone X is not a marginal case the way some later phones are; it predates the chip generation the capability depends on, so there is no path to it on this specific device.
It is also not just a chip question. iPhone X cannot run iOS 17, which DualCam requires — Apple’s newest software line drew its own line one generation later, at iPhone XS and up, so iPhone X stopped receiving major iOS versions at iOS 16. Two separate requirements, and iPhone X falls short of both at once.
A11 Bionic is one generation before the floor, not on it
Apple documents AVCaptureMultiCamSession as requiring an A12 Bionic chip or later. A12 debuted in September 2018 in iPhone XS, iPhone XS Max and iPhone XR. iPhone X came a full year earlier, in 2017, on A11 Bionic — a capable chip for its time, but the one generation that came just before simultaneous capture became possible at all.
This is different from a phone that clears the requirement narrowly. iPhone X does not sit at the edge of support the way iPhone XS does; it sits on the other side of the line entirely. No iOS update changes this, because the capability lives in how the image signal processor and camera hardware are wired together, not in a setting Apple could switch on later for an older chip.
The software ceiling would block it even if the chip did not
DualCam needs iOS 17 or later. iPhone X’s last major software version is iOS 16 — Apple’s iOS 17 release moved its own minimum supported chip up to iPhone XS and newer, which put iPhone X, iPhone 8 and iPhone 8 Plus outside it for the first time. That ceiling will not move; Apple is not going to backport a newer iOS to an A11 phone.
So the two requirements fail independently of each other: even in a hypothetical where A11 supported multi-camera capture, the iOS version alone would still stop a dual-camera app from running on this phone. There is no combination of settings or updates on an iPhone X that gets past either one.
Why this specific question comes up so often
iPhone X and iPhone XS are easy to mix up on purpose, in a sense — Apple kept the same glass-and-steel design, the same notch, and nearly the same size across both, and the name difference is a single letter. Someone reading an old review, comparing a used listing, or half-remembering which phone they owned two years apart has no visual cue to go on. The chip inside is the only thing that actually changed, and it is not something you can see from the outside.
That makes iPhone X the one model right on the wrong side of a line that a nearly identical-looking phone sits right on the right side of. It is a reasonable question to ask, not a confused one — the two phones genuinely look like the same device a year apart.
What this means in practice
If you are trying this on an iPhone X itself, the answer will not change with a software update or a setting — the device does not qualify, on chip or on iOS version, and an honestly built app should tell you that immediately rather than opening a camera view that could never produce a dual recording. DualCam performs that check at launch for exactly this reason.
If you are choosing between iPhones with this feature in mind — a used iPhone X versus a used iPhone XS, for example — the one year and one chip generation between them is the entire difference. iPhone XS, iPhone XR, or anything released after them clears the floor; iPhone X and everything before it does not, and no combination of iOS updates changes that on either side of the line.
Common follow-up questions
Is iPhone X the same as iPhone XS for this purpose?
No, and the one-letter name difference is exactly what causes the mix-up. iPhone XS runs A12 Bionic and qualifies; iPhone X runs A11 Bionic, one generation earlier, and does not.
Could a future iOS update add support to iPhone X?
No. Simultaneous front-and-back capture depends on how the A12 Bionic chip and later wire the camera hardware to the image signal processor. iPhone X’s A11 Bionic does not have that wiring, and no software update can add it.
Would iPhone X work if it could still run iOS 17?
No — the chip fails the requirement on its own, independently of the iOS version. iPhone X’s iOS 16 ceiling is a second, separate reason it would not run a dual-camera app, not the only reason.
What is the actual cutoff if I am shopping for a used iPhone?
iPhone XS and iPhone XR, both released in 2018 on A12 Bionic, are the oldest iPhones that qualify. Anything from the iPhone X generation or earlier does not, regardless of condition or storage size.
