iPhone Duo hinge cracks reported days after unboxing, sparking defect concerns

Apple iPhone Duo owners are reporting inner screens cracking along the hinge within days of unboxing, raising concerns about a possible hardware defect, though the scale and cause remain unclear. Reports on Reddit describe cracks running down the hinge's center line with a horizontal block of white pixels staying lit. Some devices broke during initial setup, and 9to5Mac notes most affected buyers received replacements at Apple Stores, though carrier purchases may face difficulties. A theory suggests a defective hinge component, slightly misaligned and protruding toward the screen, may cause the damage. Apple has not issued official guidance, and only a small percentage of shipped units appear affected.
