iPhone Duo displays crack along hinge on launch day for some owners

Some iPhone Duo owners are reporting that the inner display is cracking along the hinge on launch day, a major defect for Apple's first foldable device. The crack runs top to bottom at the fold, causing a bright white pixel line on the right side. Reports have emerged from users in the U.S., Australia, and China, though the defect's prevalence is unclear. One Australian user received an on-the-spot replacement at an Apple Store after the crack appeared within six hours and fewer than 20 folds. Apple may collect broken devices to investigate and fix manufacturing issues.
