iPhone Duo screens crack at hinge within 24 hours of launch

Apple's new foldable iPhone Duo is already showing display cracks along the hinge within 24 hours of launch, with early adopters worldwide reporting the defect. Photos on Reddit show consistent cracking patterns from top to bottom at the fold point, causing bright white lines on screens. Users in the U.S., China, and Australia report audible cracks after minimal use, with Apple offering replacements in stores. Independent durability tests by JerryRigEverything found the device failed, with dust entering the hinge and a bend test causing permanent screen damage. Apple's one-year warranty and 14-day return window cover affected units.
