# Apple Investigates iPhone Duo Screen Cracking Linked to Supplier Defects Defective hinge materials are causing internal screen failures in a limited number of units. - **Source:** [Tom's Guide](https://www.tomsguide.com) - **Published:** 2026-11-09 - **Topic:** [technology](https://brifing.si/c/technology) - **Original article:** - **On Brifing:** https://brifing.si/s/28b5b2e1-29fd-4924-b9fb-f9d95745005b ## Unexpected Screen Failures iPhone Duo users are reporting internal screen cracks occurring without apparent physical impact. This phenomenon, labeled as crackgate, has sparked concerns regarding the durability of Apple's first foldable device. While social media reports suggest widespread issues, Apple maintains that only a small number of units are currently affected by these failures. ## Tracing Supplier Defects Leaked information suggests the root cause is defective materials sourced from one of two hinge suppliers. This indicates the problem is isolated to specific manufacturing batches rather than a fundamental flaw in the device's hinge design. Consequently, the majority of iPhone Duo units are expected to remain free from these defects. ## Serial Number Identification Reports indicate that Apple can identify potentially affected devices using their unique serial numbers. This capability allows the company to potentially track which units contain the substandard hinges. Proactive identification could enable Apple to manage the situation more effectively, though the company has not yet announced a formal public tracking tool. ## Repair and Replacement Policy Apple is currently bypassing standard repair wait times for affected customers. Users experiencing screen cracks are being offered free device replacements under the standard manufacturing warranty. Notably, this policy applies regardless of whether the user holds a paid AppleCare+ plan, ensuring support for all owners of the impacted foldable units. ## Warning Signs for Users Social media reports suggest that a raised bump on the hinge may appear before the internal screen actually cracks. Users are advised to monitor their devices closely for any physical irregularities. If such signs emerge, owners should immediately contact Apple support or visit an Apple Store for a professional hardware inspection. ## Supply Chain Uncertainty The total number of units produced with the faulty hinges remains undisclosed. It is unclear if this manufacturing issue will impact delivery timelines for customers currently waiting for their iPhone Duo orders. The limited initial supply of the device makes it difficult to gauge the true scale of the hardware defect. ## Design Integrity Confirmed If the reports regarding supplier-specific material defects are accurate, the iPhone Duo's core engineering remains sound. This distinction is vital, as it suggests the foldable design is not inherently prone to failure. Future production runs using different materials should theoretically resolve the issue, preventing the device from becoming a widespread liability. ## Future Mitigation Strategies Apple faces a choice between waiting for failures to occur or proactively reaching out to owners of affected serial numbers. Implementing a public serial number verification tool could stop the spread of negative social media imagery. Moving forward, the company must ensure stricter quality control protocols with its hinge component suppliers. ## Sources covering this story - [Tom's Guide — Apple Investigates iPhone Duo Screen Cracking Issues Linked to Supplier Defects](https://www.tomsguide.com/phones/iphones/iphone-duo-crackgate-could-be-at-an-end-as-leaker-claim-apple-has-figured-out-why-some-screens-have-been-randomly-breaking) - [r/Apple: Unofficial Apple Community — Rumored End to iPhone Duo 'Crackgate' Issues](https://www.reddit.com/r/apple/comments/1xrvrda/iphone_duo_crackgate_could_be_at_an_end_leaker/) --- _Summary written by Brifing from the original reporting.
