iFixit Probes iPhone Duo Screen Failures, Suspects Hinge Stress Point

iFixit is investigating whether the iPhone Duo's hinge geometry could explain reports of inner-screen failures, identifying a possible stress hotspot near the center support but stopping short of confirming the cause. Owners have reported hearing a pop or crunch when opening or closing the phone, followed by bright lines across the display. Damage clusters near a flex cable crossing point, with a hypothesis that a center support bar may not drop far enough, allowing the curved display to press against it. Pressure, trapped particles, and manufacturing defects are also possible explanations. Despite vulnerabilities, iFixit awarded the Duo a provisional 5 out of 10 for repairability, its highest score for a foldable smartphone. The outer display and batteries were easily removable, but the inner screen and hinge require substantial disassembly, with a $999 out-of-coverage service charge. The nano-texture cover scatters reflections to hide the crease but scratches easily.
