YouTuber tears down iPhone Duo, points to weak hinge link behind screen cracks

Owners of Apple's foldable iPhone Duo have reported screens cracking at the same spot, sometimes within hours. YouTuber CuriousHagi reproduced the failure during durability tests and then took the phone apart. He found that one hinge link in the middle is thinner than the others and snapped at a small notch, with marks suggesting the hinge was catching on the support plate.
