CuriousHagi reproduces an iPhone Duo screen crack during testing

YouTuber CuriousHagi reproduced an iPhone Duo screen crack during durability testing, according to The Verge. The test recreated a failure that users have described on social media and the iPhone Duo subreddit, where some say the hinge catches before the screen audibly cracks and breaks.

The Verge says users have reported experiencing the problem after owning the phone for only a few hours. Those accounts describe cracks forming in the same area of the screen. The reported sequence is a hinge that appears to catch, followed by a crack and screen break; the outlet does not establish that every device fails this way.

After reproducing the damage, CuriousHagi took apart the device to look for a possible source. The Verge describes the hinge assembly as complex: it has a gear-like central hinge along with two different types of linking hinges. The account identifies the hinge as an area of concern, but does not report a confirmed engineering finding that explains why the screen cracks.

JournalArta’s headline likewise characterizes CuriousHagi’s teardown as pointing to a weak hinge link behind the screen cracks. That headline supports the general hinge-related framing, but offers no further details about the testing or the teardown. The Verge’s account presents the hinge as a possible weak spot rather than a proven cause.

The reports described in The Verge raise a practical concern for iPhone Duo users: a screen can reportedly crack after the hinge catches, and users say the damage appears in a recurring location. CuriousHagi’s test shows that the break could be reproduced under durability testing, while the teardown offers a closer look at the hinge’s multiple components.

The Verge also notes that social media and the iPhone Duo subreddit contain accounts of the device failing quickly. Those posts are user reports, not a quantified measure of how often the failure occurs. The account gives no total number of affected devices and does not report a statement from Apple about the reported cracks.

The central issue documented so far is whether the hinge’s structure is connected to the recurring screen damage users describe. The Verge’s account and JournalArta’s headline both point toward the hinge, while the reported teardown details the assembly’s components without establishing which part, if any, causes a crack.
