iFixit has identified a possible mechanical explanation for some reported iPhone Duo inner-screen cracks: a central hinge support bar may press against the folding display if it does not retract far enough during closing.
The teardown offers a hypothesis, rather than a confirmed cause covering every affected phone.
A possible pressure point beneath the fold
Using teardown footage, patents and CT scans, iFixit built a 3D hinge model and compared it with reported damage. Several breaks appear near the transition between the cross-device cable opening and the central hinge support.
In its simulation, a support bar that fails to lower sufficiently creates a concentrated stress point as the screen folds onto it. The team presents this as one possible explanation, not a demonstrated fault in every unit.
A bright line can exaggerate the damage footprint
A small failure in electrical connections can disrupt a full row or column of pixels. Consequently, long bright lines do not necessarily mean the entire visible line has physically cracked.
The phone received a provisional repairability score of 5/10, with complex inner-display and hinge repairs among its weaknesses.
What the findings mean for readers
For Malaysian owners following the reports, the distinction between an investigative lead and a confirmed diagnosis matters. These findings alone cannot establish a failure rate or determine the cause of an individual phone’s damage. They also do not establish a recall or a Malaysia-specific replacement policy.
