iFixit identifies possible stress point in iPhone Duo hinge

iFixit has proposed a potential stress point in the iPhone Duo's hinge, though its simulation and stress tests have not identified the cause of reported screen cracks. The hypothesis remains unconfirmed. MacRumors published the simulation on October 25, suggesting a central support bar may not lower enough during closure, contacting the folded screen. Reports of damaged displays near the hinge emerged October 23, with one Australian owner citing cracks after six hours and fewer than 20 opens. iFixit built a 3D hinge model from teardown images and patents, noting a possible tension point near the flexible cable gap. It gave the iPhone Duo a provisional repairability score of 5 out of 10, describing the inner screen and hinge as difficult and costly to repair.
