Apple will replace iPhone Duo units whose inner screens crack at the hinge

Apple’s first foldable phone has a hardware problem in its first week on sale. Over the weekend of October 24 and 25, iPhone Duo owners began posting photos of inner displays cracked along the fold. On October 26, Apple told 9to5Mac it knows about the issue and will replace affected phones through AppleCare.

The timing makes this more than a forum story. The iPhone Duo reached stores on October 23 in the US and more than 70 other countries and regions, according to MacRumors, and Apple’s launch release added 28 more countries from October 30. It costs $1,999 for 256GB and $3,199 for 2TB. A wider rollout is happening while the cause is still unknown.

What owners are seeing

On October 25, 9to5Mac’s Benjamin Mayo counted about ten separate cases, with more on the r/iPhoneDuo subreddit. The failures look alike: a crack down the centre line of the hinge, then a horizontal band of pixels stuck glowing white. Some phones had been out of the box for less than a day, and a couple of owners said the screen broke during first setup.

One owner who bought through a carrier said they were told the phone must have been dropped and that they would have to pay for the repair. That is the scenario most buyers will worry about, and Apple’s statement a day later addressed it.

“We are aware of an issue impacting the inner display on a small number of iPhone Duo units.”

That line comes from Apple’s statement to 9to5Mac. Apple said affected owners should contact AppleCare for a replacement. According to 9to5Mac, an AppleCare+ plan is not required, and people who bought from a carrier should go to AppleCare directly rather than back to the carrier.

Two caveats apply. Apple has not said how many units are affected or what causes the failure. And 9to5Mac’s Chance Miller noted that a handful of the Reddit posts were fake, AI-generated images, so a count based on social media will overstate the problem by some unknown amount.

What the teardown points to

iFixit’s teardown, published on October 25, does not name a single cause. The team built a 3D model of the hinge from CT scans, teardown footage and Apple’s patents, then compared it with where the screens broke. The reported cracks cluster where the gap for the display’s flex cable meets the central hinge support.

iFixit offers one possible answer. In its closing simulation, the centre support bar “fails to drop far enough” when the phone shuts, and the screen’s curved fold then lands on it, creating what iFixit calls a small stress hotspot near the break location. It stresses that several edges meet at that spot, so there are other possible culprits, and asks whether the centre pivot, which looks different from the rest of the hinge, could be getting stuck.

Apple’s launch materials made strong durability claims. The release says the phone “is built to last”, describes custom adhesives that let the display layers slide “like the pages of a book”, and lists a titanium plate under the panel with high-strength glass above and below it. What it does not give is a fold-cycle rating. Its one hinge claim, more than 100 components that “support the center of the display”, covers exactly the area iFixit’s simulation now questions.

The repair bill if you are out of warranty

iFixit gave the iPhone Duo a provisional 5 out of 10 for repairability, its best score for any foldable so far. The outer screen came off cleanly and both batteries use adhesive that releases with an electric current. The inner display and hinge cost the most points, and iFixit lists an out-of-warranty inner display repair at $999.

“The early reports of screen failures make clear that display replacement is more than a distant possibility.”

That is iFixit’s own conclusion, and it changes the cost of owning this phone. On a regular iPhone, accident cover is a nice extra. On a phone whose inner screen costs about half the purchase price to replace, it is close to essential. Apple’s release says AppleCare+ covers accidents such as drops and spills.

What to do now

If you already own an iPhone Duo and see a crack or a stuck white band, go to Apple, not your carrier, and point to Apple’s statement. Take photos of the phone’s frame and corners first, so a claim that the phone was dropped is easy to answer. Do it while the phone is under warranty rather than waiting to see whether the damage spreads.

If you have not bought one yet, the open question is whether units shipping now differ from the first batch. Apple has not announced a hardware change, and nobody outside Apple knows whether replacement phones use a revised hinge. Buyers who need the phone now should buy where returns are simple and keep the packaging. Everyone else loses little by waiting a few weeks, which should show whether failures keep appearing in later stock and in replacement units.

Three things are still unknown: the cause, the failure rate, and whether Apple will set up a formal repair programme instead of handling cases one by one through AppleCare. Until Apple answers at least the first two, the iPhone Duo’s main risk sits in the part that makes it a foldable.
