ItInsightsWorld: iPhone Duo Inner Display Crack Reports Limited to Very Few Devices While Repair Details Stay Unclear

A crack problem reported shortly after the first foldable iPhone Duo launched has now received a response from Apple. The company says only a very small number of devices are affected, but it has not explained what caused the inner-display cracking or whether a repair plan is coming.

What Apple said to MacRumors

In a statement provided to MacRumors, Apple reiterated that the issue involves very few iPhone Duo devices. It did not disclose a root cause, and it did not say whether it will introduce a fix. Apple wrote: “Early user feedback on iPhone Duo has been very positive, and we are seeing developers quickly update apps to take full advantage of its unique form factor, which is exciting. We have learned that a very small number of iPhone Duo devices have issues with the inner display. If a user encounters a problem with the iPhone Duo screen, they should contact AppleCare for replacement service.”

Where the inner screen cracks appeared

The reported failures show a repeated pattern. Cracks were described on the lower portion of the inner display in the same area, extending along the hinge. Before visible damage appeared, some users said the folding section felt stuck, sometimes with a slight pop. That sequence suggests the issue is more likely related to a mechanical irregularity in the hinge during repeated opening and closing than to an external impact such as a drop.

Possible hinge causes identified by iFixit

Repair analysis from iFixit opened the iPhone Duo and listed several possible ways the hinge could fail. The fault zone contains multiple internal components. One possibility is that the central support bar inside the hinge, which should retract, did not retract normally, then pressed on the flexible inner display and caused damage. This aligns with the user reports of a stuck feeling and a pop.

Replacement options and remaining unknowns

At present, affected users can receive a full-device replacement at Apple retail stores. However, limited stock means some may need to wait before the replacement is finished. Because this is a newly launched device with a relatively high starting price and production capacity still ramping, that wait can extend the time required to resolve the problem. As of press time, Apple has not published the batch range or failure rate of affected devices, and has not indicated whether software updates or hardware revisions will be used. Prospective buyers should watch for a stuck feeling, unusual noise, or fine cracks near the hinge area of the inner display and contact AppleCare early to prevent further damage.
