YouTuber Discovers Hinge Design Fault Behind iPhone Duo Crackgate

Reports of the iPhone Duo’s rapid, spectacular failures have swirled across social media and the device’s subreddit, with users noting that the screen cracks in the same spot after only a few hours of use. YouTuber CuriousHagi reproduced the cracked screen during durability testing and then disassembled the phone to locate the root cause. He found that the Duo’s hinge is unusually complex, combining a gear‑like central hinge with two distinct types of linking hinges. The intricate arrangement appears to concentrate stress at a single point, leading to the audible crack and screen break. The discovery clarifies why the failures occur in a predictable location and provides a concrete mechanical explanation for the widespread “crackgate” reports.
