iPhone Duo durability test reveals why broken screens are rare at launch

A YouTuber's durability test shows the iPhone Duo's display is more resilient than expected, potentially explaining the low number of broken units reported since launch. The device survived extreme bending and scratching despite some damage. In the video by JerryRigEverything, the outer Ceramic Shield display resisted scratches up to level seven on the Mohs scale, while the flexible inner screen scratched more easily, similar to other foldables. A bend test caused screen line faults but did not snap the phone, and the hinge held under pressure. Despite social media posts showing cracked screens, AppleInsider surveyed seven Apple stores, including four flagships, and found no devices returned for broken displays. The central fold remains the most vulnerable area, but early failures appear rare relative to sales volume.
