Overview of the problem
Within hours of the Apple iPhone Duo hitting stores on 23 October, owners began posting videos that show a noticeable gap between the back panel and the hinge when the device is closed. The gap exposes the hinge mechanism and suggests that the back panel has lifted or bowed. This defect is especially concerning because the iPhone Duo is marketed as the first foldable with an IP68 rating for water and dust resistance.
First reports from the community
Reddit user MICAPe9 posted a short clip titled Check your Duo, highlighting the space that appears at the top half of the phone. Another commenter, MrOsterhagen, confirmed seeing the same gap on his unit and noted a small but visible bow in the upper section of the device. Several other users have since shared similar photos, indicating that the issue may affect a small batch of units rather than being an isolated case.
Apple’s response
Tech analyst Mark Gurman amplified the concern on X, acknowledging that the problem is real. Apple issued a brief statement saying it is aware of an issue impacting the inner display on a limited number of iPhone Duo units and advised affected owners to contact AppleCare for a replacement. The company did not provide details about the root cause or a timeline for a fix.
Related hardware flaws
In addition to the hinge gap, users reported cracks appearing on the right‑hand side of the inner display shortly after unboxing. The damage appears in the same spot across multiple devices, suggesting a faulty hinge that puts pressure on the flexible screen. This mirrors earlier “CrackGate” reports that surfaced during the initial rollout.
Comparison with competing foldables
The Samsung Galaxy Z Fold 8, announced alongside the Apple iPhone 18 and iPhone 18 Pro at Samsung’s September Surprise and Shine event, launched without the same early‑stage hardware complaints. While the Z Fold 8 also faces its own durability questions, it has not been reported to suffer from a systematic hinge‑gap issue. Apple’s late entry into the foldable market means expectations were high, and the iPhone Duo’s launch has felt rushed compared with the more polished rollout of competing devices.
Software ecosystem challenges
Beyond hardware, the iPhone Duo launch was hampered by a lack of optimized third‑party apps. Even after Apple’s 22 October press release promising a wave of apps and games tailored for the foldable, many popular titles remained unavailable when the phone reached stores. This lag in software support added to the perception that the Duo’s debut was a scramble rather than a coordinated launch strategy.
Looking ahead
If Apple can address the hinge gap and display cracking through a swift repair program, the iPhone Duo may still win over its fan base, especially when paired with accessories like the Apple Watch Series 10 or the iPad Air M2. However, repeated hardware setbacks risk tarnishing Apple’s reputation for premium build quality. The industry will be watching closely to see whether “GapGate” becomes a footnote or a lasting blemish on Apple’s foldable ambitions.
