Reports of iPhone Duo screen failures have surged, with users describing cracks forming in the same location after brief use. A YouTuber named CuriousHagi conducted a detailed analysis of the device, identifying a potential design flaw in its hinge system. During durability tests, he was able to replicate the cracking issue, leading to a deeper inspection of the phone's internal components. The hinge, which is composed of multiple interlocking parts, appears to have a structural weakness. Specifically, a thinner link in the middle of the hinge snapped at a small notch, indicating a point of vulnerability. The analysis also revealed marks where the hinge may have caught on the support plate, contributing to the cracking. These findings align with user reports of consistent crack locations, suggesting a systemic issue rather than isolated incidents. The implications of this discovery could affect consumer confidence and potentially influence future product designs. As more users report similar issues, the pressure on Apple to address the problem intensifies.
