Overview
- Apple launched the iPhone Duo on Oct. 23 and within days some buyers in the U.S., India, Australia, Canada and China reported cracks, bright lines or other display damage along the phone’s inner fold.
- Apple told Xinhua it has seen a "small number" of affected units and told MacRumors that users with inner‑screen faults can contact AppleCare to request a replacement.
- CNET has run a live durability experiment on a retail iPhone Duo in Louisville that passed more than 103,000 folds without visible hinge or screen failure and the test is continuing until the device breaks.
- Teardown analyst iFixit has suggested, as an unconfirmed hypothesis, that the hinge’s internal parts could concentrate stress on the inner screen when the phone folds, but Apple has not verified this theory.
- Because Apple has not released failure counts, rates, or a technical cause, investigators will need wider field data to tell whether the problem is a rare defect, a manufacturing batch issue, or a first‑generation design limitation that could affect early adopters.
