Over the weekend, a handful of iPhone Duo users reported that their inner display had cracked along the hinge.
Apple issued a statement to 9to5Mac, saying it is “aware of an issue impacting the inner display on a small number of iPhone Duo units,” and that affected users can contact AppleCare for a replacement.
The company emphasized that the problem affects a very small number of devices and appears quickly, noting that most iPhone Duo units are unaffected and that a replacement does not require AppleCare+. If a device was purchased through a carrier, users should contact AppleCare directly rather than the carrier.
Reports of the crack spread on Reddit and other forums, with some posts being legitimate while others were identified as fake AI‑generated content. iFixit pointed to potential causes, suggesting that certain components may place excessive pressure on the display. Despite the issue, Apple highlighted the positive early reception of the iPhone Duo, noting that developers are rapidly updating apps to leverage its unique form factor. The issue was first noticed over the weekend, and Apple confirmed that the defect appears relatively rapidly, though it remains limited to a tiny fraction of the total shipment.
