Apple confirmed a small number of iPhone Duo units are experiencing inner display cracks along the hinge, directing affected users to contact AppleCare for replacements. The issue was reported by early users three days after the device's launch, with some experiencing cracks during initial setup. Apple's statement emphasized the problem's limited scope but did not specify technical causes.
A defect in the hinge's central support bar may cause excessive pressure on the display, leading to cracks along the midpoint. iFixit's teardown identified multiple hinge components as potential failure points, though no definitive cause was confirmed. Some reports suggest the issue appears quickly after purchase, while others note fake images circulating online.
Apple stated most users would not encounter the issue, but affected owners without AppleCare+ can still receive replacements. Some reported receiving devices through Apple Stores, though stock availability varies. The company has not disclosed the number of affected units or plans for hardware revisions.
