Apple will replace iPhone Duo handsets with inner display problems, days after its first foldable phone went on sale.

The company confirmed the iPhone Duo screen replacement offer on Monday, October 26, telling affected owners to contact AppleCare for a replacement unit. Apple described the issue as one affecting a small number of units, and it did not say how many phones are involved or what causes the damage.

That timeline matters because the phone only reached stores on October 23, priced from $1,999, with initial online orders selling out in minutes. Owners started posting photos over the weekend of cracks and bright lines across the 7.6-inch inner display, mostly where the phone folds.

That was fast.

What Apple said, and what it didn’t

Apple’s statement was short, and the gaps in it are now the story. “We are aware of an issue impacting the inner display on a small number of iPhone Duo units,” Apple said in a statement. “If users experience issues with their iPhone Duo display, they should contact AppleCare for a replacement.”

Reuters reported that affected units tend to show the problem quickly, which fits the weekend pattern: phones that had barely left the box were already showing lines along the fold. Apple did not comment on what might cause the issue, and it did not immediately comment on iFixit’s separate findings about the hinge.

How the damage showed up

Over the weekend, social media posts showed the Duo with cracks and lines in the inner display along the central hinge where the phone folds, according to Reuters. Some owners also reported hearing a crunching noise when opening the device, and others shared photos of lines running across one side of the unfolded screen.

One owner cited by the BBC, Justin Lokos, posted an image showing lines across the right side of his display. He later shared a photo of a replacement handset alongside the damaged device and thanked an Apple store in New York for its help, according to the BBC’s account.

Don’t read every photo online as proof of a broken phone. The BBC’s account also noted that the extent of the problem remains unclear, and that some images circulating online may have been generated or manipulated using artificial intelligence.

What iFixit found in the hinge

iFixit, the repair firm that publishes teardown reports and repair guides, went looking for a physical explanation. It said it used teardown footage, patents, and CT scans to build a 3D simulation of the Duo hinge, then compared that model with the reported damage locations.

Its finding points to one spot. iFixit said the reported damage clustered just below where a display cable runs under the screen near a central support bar. That bar might be failing to drop out of the screen’s way as the phone is folded, “creating a small stress hotspot near the reported break location,” the company said.

Apple did not immediately comment on those findings, Reuters reported. iFixit also concluded that the Duo is the most repairable foldable phone it has tested, an odd counterpoint to a launch-week display problem.

Foldable hinges have bitten other makers before. Samsung faced a similar setback in 2019 when reviewers reported screen failures in its first foldable phone, the Galaxy Fold, shortly before its planned launch.

iPhone Duo screen replacement: what owners should do

If your Duo shows cracks, lines, or bright marks on the inner display, Apple’s stated route is AppleCare. Contact AppleCare, describe the inner display problem, and ask for a replacement unit. Note when the problem first appeared, since Reuters reported that affected units tend to show it quickly.

If your phone looks fine, Apple has announced nothing for you to do. No recall, no inspection program, and no software fix have been mentioned in the reporting so far. That could change if Apple finds a cause that points to a wider batch, but for now the offer covers units that actually show display trouble.

Why this matters

Francisco Jeronimo, a vice president at market research firm IDC, said Apple’s quick replacement offer was the “right first step” in responding to the problems, according to Reuters. He’s right about the speed, but speed alone doesn’t settle the question that matters most: is this a handful of early units, or the first sign of a hinge design that needs a fix?

For Apple, the stakes go past one phone. The Duo is the company’s first foldable, its entry into a category rivals have sold for years, and a $1,999 statement that Apple can charge more than anyone else for a phone. A small, well-handled replacement program would barely dent that story. A growing count of cracked displays, or a confirmed hinge flaw, would land differently, because it would hit the exact part of the phone that makes a foldable worth buying.

Watch the next data point, not the next headline. If Apple revises its statement, names a cause, or widens the offer, that will tell buyers more than any teardown can. Until then, the honest summary is the one Apple gave: a small number of units, a replacement route through AppleCare, and a cause that remains unconfirmed.
