YouTuber identifies potential design flaw behind widespread iPhone Duo screen cracks
Durability testing and teardown analysis suggest a thinner hinge link with a structural weak point may be causing the device's documented cracking failures.
What happened
YouTuber CuriousHagi reproduced cracked screens during durability testing of the iPhone Duo, then disassembled the device to investigate. He found the hinge assembly consists of a gear-like central hinge with multiple linking hinges of varying thicknesses. The middle linking hinge is notably thinner than adjacent links and fractured at a small notch where it would be mechanically weakest. Evidence of marks where the hinge met the support plate suggests the mechanism may have caught during failure.
Context
Multiple reports on social media and the iPhone Duo subreddit document rapid screen failures, with some users experiencing cracks within hours of purchase. The failures cluster at the same location, suggesting a systemic design vulnerability rather than isolated defects. If the hinge link design is indeed the root cause, this represents a potential widespread durability issue affecting the device's core function and user experience.
What's disputed
The finding is based on one teardown analysis; no statement from Apple or confirmation of the flaw as the universal cause across all reported failures has been reported in the source.
