Some iPhone Duo Owners Report Cracked Screens, and Apple Will Replace Them
Apple says it knows about "an issue impacting the inner display" on a "small number of iPhone Duo units." Owners of affected phones should contact AppleCare for a replacement.
Owners have described cracked inner screens. In many cases, the crack is a bright line that runs from the middle of the screen to the right edge. Bloomberg reported on Sunday that the complaints are still early. They focus on the foldable inner screen, which measures 7.6 inches.
The damage seems to start at the hinge, the part that lets the phone fold. Some users said the hinge got tight, and that opening the phone caused a crack and bright lines on the screen. One owner told the New York Post they heard a crack as they opened the phone. The screen broke along the hinge. MacRumors reported on October 23 that hinge problems were already causing cracks. Photos of damaged screens were shared on Reddit and in the MacRumors forums.
Two explanations have spread after people took the phone apart. 9to5Mac reported a theory that the hinge contains a faulty part. In this theory, one piece sits slightly out of place and pokes up into the inner screen. iFixit's teardown analysis suggested the foldable screen may press against a metal bar in the middle of the hinge, right where the damage appears.
The screen is a delicate part. According to 9to5Mac's review, the inner display is built from more than 10 very thin layers. Think of a stack of paper sheets that must bend back and forth thousands of times without tearing. If one spot inside the hinge is slightly off, the bending force gathers at that one line. That is the mechanism the teardown theories describe. It would explain why a single misaligned part would cause a crack in one specific place, not random damage across the screen.
The phone's launch also matters here. Bloomberg reported on October 23 that the iPhone Duo starts at nearly $2,000 and that Apple quickly sold out of its limited in-store stock. Earlier, on October 16, Bloomberg reported that shipping times for both colors stretched from November into December. For some orders, the wait reached the end of January. Fewer phones in people's hands means fewer people testing them, which may explain why the number of affected units is still described as small. It also means AppleCare replacements will be the main way these cases get fixed.
In my view, the key question for buyers is whether the problem is limited to one hinge part or points to a wider stress issue in the screen. Apple's statement and replacement instructions deal with the first case. The second would take longer to become clear. Owners who already have a phone should watch for a stiff hinge and lines on the screen. They should not try to force the phone open to test it.
The broader context here is that folding phones depend on a few millimeters of hinge design and a screen that must flex thousands of times without cracking. If the replacement program and any later hardware fix solve the problem quickly, this episode may be remembered as a lesson in durability for a new kind of phone, rather than a verdict on folding phones as a whole.
