GoKawiilEarly iPhone Duo units reportedly cracking at internal hinge
A user reports that their iPhone Duo foldable broke along its internal hinge after only about six hours of use and fewer than 20 open-close cycles. The owner described feeling something shift near the hinge beneath the screen, followed by an audible crack and a visible break at that point. No external damage or marks were found on the hinge or screen surface that would explain the failure.
