Teardown points to a notched hinge link behind iPhone Duo screen cracks
Reports on social media and the iPhone Duo subreddit describe screens cracking soon after purchase, often with the break in the same place. YouTuber CuriousHagi reproduced the fault during durability testing and took the phone apart to investigate a possible cause.
He found a complex hinge with a central gear-like mechanism and several linking hinges. The link that snapped was thinner than those above and below it, and broke at a small notch; marks on the hinge and support plate suggest it may have caught there.
In short
- Some iPhone Duo screens reportedly crack within hours.
- CuriousHagi reproduced the failure and examined the hinge.
- A thin, notched hinge link may be the weak point.
Explained simply
The iPhone Duo is a foldable phone, with a flexible screen that bends as the two halves open and close. A hinge supports the fold and helps the screen move with the phone, so its design can affect how the screen holds up over time.
CuriousHagi is a YouTuber who tests devices and examines how they are built. In a teardown, a phone is taken apart to inspect its components; here, the hinge links and the plate supporting them are relevant because they sit beside the folding screen.
