  "account": "A YouTuber scrutinized the hinge of the iPhone Duo through a CT scan, revealing its intricate design and limitations. The iPhone Duo launch surprised many by offering multiple functions at various angles, unlike conventional smartphones. According to HTX Studio's testing, the iPhone Duo can remain open between 15 and 145 degrees. Below 15 degrees, the phone snaps shut due to magnets, while beyond 145 degrees, the screen unfolds fully. The hinge comprises nearly 100 components, concentrated in six sections. Two outer sections consist of hinges connected to a central shaft, while the middle sections involve gears that rotate in unison. Above and below the middle section are mixtures of springs and cams that either support or resist each other, depending on the screen's angle. When fully open, the cams align with the springs, while the springs press against them when folded, creating frictional torque that overcomes the phone's weight. A central section houses flex cables connecting the two sides of the device. The screen's curved design utilizes a \"bending space\" of 3.85mm, which is comparable to other foldable phones. Unlike most rivals, the iPhone Duo lacks bumps at the crease to protect its hinge, opting for a smooth screen instead. The hinge assembly is encased in a titanium cover for added strength, allowing the iPhone Duo to support an Apple Pencil without leaving visible marks on the display.",

HTX Studio used a CT scan and then built a 3D model of the iPhone Duo hinge to examine it - image credit: HTX Studio. One of the surprises at the iPhone Duo launch was how it wasn't just built to either be fully open or fully closed. Instead, Apple has built it to offer…",
