YouTuber’s teardown points to design flaw behind iPhone Duo’s “crackgate” failures

A popular technology YouTuber who recently opened up an iPhone Duo claims to have pinpointed the mechanical weakness that is causing the device’s screens to shatter shortly after purchase, a problem that has been dubbed “crackgate” on social media.

Since the Duo’s launch, members of the iPhone Duo subreddit and numerous TikTok and Twitter users have shared videos of the foldable phone snapping shut, emitting a distinct cracking sound, and leaving the display fractured within a matter of hours. Many describe the hinge catching on an unseen obstruction before the audible break, suggesting a repeatable failure mode rather than isolated accidents.

In his detailed disassembly, the creator documented that the hinge’s internal spring mechanism is positioned too close to the glass panel, creating a high‑stress concentration point at the fold line. He noted that the metal housing that should shield the glass is undersized, allowing the hinge’s metal pins to press directly against the screen during normal opening and closing. According to his measurements, the tolerance gap is less than half a millimeter, leaving virtually no room for manufacturing variances.

The issue arrives at a time when Apple is still refining its entry into the foldable market, an arena dominated by Samsung and Huawei. Foldable smartphones demand precise engineering to balance durability with the thin, flexible displays that consumers expect. Early prototypes from other manufacturers have suffered similar setbacks, but Apple’s brand reputation amplifies scrutiny whenever a design flaw surfaces.

Consumers who have experienced the breakage are facing costly repairs, as the Duo’s screen is not considered a standard replacement part. While Apple’s warranty covers manufacturing defects, the company has not yet issued a formal statement linking the incidents to a specific design oversight, leaving owners in a gray area between warranty coverage and out‑of‑pocket expenses.

The YouTuber’s findings have sparked a wave of discussion among tech enthusiasts, with some urging Apple to initiate a recall or at least a firmware update that could modify hinge tension. Others caution that a software fix may be insufficient if the root cause is purely mechanical. So far, Apple has responded only with a generic reminder to contact support for malfunctioning devices.

Analysts say the next steps will likely involve Apple’s engineering team reviewing the hinge geometry before the Duo’s next production run, possibly delaying future shipments. Observers will be watching for any official acknowledgment or a targeted repair program, both of which could influence consumer confidence in Apple’s foldable ambitions as the market continues to expand.
