iPhone Duo Durability Concerns Rise After Hinge and Screen Failures in Tests

Apple's first foldable iPhone Duo has reported cases of cracks or bright lines at the inner screen hinge since launch, raising concerns about quality and durability, though Apple has not yet publicly responded. The issues emerged after tech reviewer JerryRigEverything's extreme durability tests, which included sand exposure and bending. The device failed dust protection, with sand jamming the hinge, and a green line appeared on the screen during bending, though the cause remains unclear. The iPhone Duo, priced at 74,900 yuan, previously passed 32,000 open-close cycles in a test by journalist Joanna Stern. Whether the hinge and screen withstand normal long-term use remains a key consumer concern.
