The spate of iPhone Duo screen issues has allegedly been traced to a material problem at a hinge component supplier, rather than there being a design flaw with the hinge itself.

Apple put a lot of work into designing the ideal hinge for the iPhone Duo, only to deal with reports of the hinge repeatedly failing in one specific place. It now seems that the problem was due to the components Apple used.
According to Chinese leaker Kang, reposted by Ice Universe, the hinge issues are due to the materials used for a specific component in the hinge. This is a component sourced from two suppliers.
