iFixit iPhone Duo Teardown Points to Possible Cause of Screen Cracks

To see where the stresses build up from folding, we built a 3D hinge model from teardown footage, patents, and CT scans, then compared it with the reported damage locations.

The breaks cluster near the transition from the gap for the crossing flex cable to the central hinge support.

The damage we're seeing in photos isn't right where the display cable passes through the hinge, but slightly lower, at a point where several edges meet and change how the thin display is supported as it bends.
