iPhone Duo inner screens crack early; teardown points to hinge support bar

Tucked under the inner screen of Apple’s first foldable is a hinge built from more than 100 components, and in the middle of it sits a flat center support bar. Its job is to hold the middle of the display flat when the phone is open. iFixit’s teardown suggests that bar may be the problem: in the repair company’s stress simulation, it does not always drop out of the way as the screen folds.¹²

The spot in question is where a display cable crosses the hinge. The bar’s shape there makes several edges, and iFixit’s lead teardown technician, Shahram Mokhtari, told The Verge the damage lines up with a black spot where metal appears to press into the flexible panel. He says the inner screen is “extremely sensitive.”²

In plain terms, the theory is that a stress hot spot forms between the flat bar and the bent screen when the Duo is closed. This is iFixit’s reading, not an Apple finding, and it rests largely on iFixit’s teardown plus owner photos and posts on Reddit and social media. The cause has not been officially verified.²³

The Duo went on general sale on Friday, October 23. Owners soon posted photos of screens with a crack or glitch above the hinge and lines running down one side.²¹ One Australian owner wrote that the screen broke within six hours; they felt something near the hinge, kept opening the phone and heard an “audible crack.” The Guardian could not verify that account, and the owner said the local Apple store replaced the phone straight away.¹ Bloomberg also reported similar issues in the US and India.¹

Apple has confirmed “an issue impacting the inner display on a small number of iPhone Duo units” and tells owners to contact AppleCare for a replacement.³¹ It has not said how many phones are affected. Mokhtari said Apple likely holds more data than it is sharing.²

Experts the Guardian spoke to say it is too early to call this widespread. IDC’s Francisco Jeronimo called early problems common with a new product and said Apple’s replacement offer is the right first step. CCS analyst Ben Wood said there is no evidence yet of a broader fault.¹ WIRED’s own review unit has had no trouble after more than two weeks of daily use.³

Mokhtari said the phones are in people’s hands and mostly working fine. A certain number of foldable screens and hinges will fail, he said, because both are delicate. Apple is not recalling the Duo. If the same failures keep showing up three months from now, he said, the problem would look more widespread and could lead to a recall. He also expects Apple to redesign the part at fault for its next foldable, though that is his prediction, not an Apple statement.²

The repair picture matters here. iFixit gave the Duo a provisional 5/10 repairability score, the highest it has given any foldable. The battery and back panel are straightforward to swap, but the inner display is held on with adhesive that has to be softened with a heat gun, and Apple’s inner screen repair service costs $999.³ The Duo starts at $1,999.⁴

On the bench: if you own a Duo, open and close it gently, and if the inner screen shows a crack, a white strip or lines, take it to AppleCare, which is replacing damaged units. If you are still deciding, the $999 inner screen repair bill is the number to weigh, since the replacement offer is the safety net for now and iFixit’s three-month benchmark is the one to watch.³²
