[DiaryPoint=Reporter Eom Ju-yong] Reports say the iPhone Duo’s hinge issue may stem from the materials used in a particular component rather than a design flaw. Coverage citing a Weibo post by Kang, a Chinese leak account, said on November 9 that the component was sourced from two suppliers.
Users had previously posted photos and accounts online showing lines on the inner foldable display or cracks near the hinge. In a case reported on October 23, an Australian user said a crack appeared after fewer than 20 folds; reports said Apple replaced the device.
In a statement to media outlets, Apple said it was “aware of an issue affecting the internal display on a small number of iPhone Duo devices.” The company advised users experiencing display problems to contact AppleCare and ask about a replacement. Service eligibility and cost depend on the device inspection and warranty terms.
According to coverage citing Apple’s guidance on hinge problems, symptoms to check include a device that will not open or close fully, unexpected sounds when opening or closing it, and a hinge that feels loose, bent, or broken. Apple advises users to first remove the case and screen protector, then check for dust or debris around the hinge and dents or scratches on the exterior.
If the hinge catches or makes an unusual sound, avoid forcing the device open or closed. It may help to document the symptoms and the device’s exterior before booking an inspection through Apple Support. If the display develops a crack or bright line, contact AppleCare or an Apple Authorized Service Provider to check repair or replacement options and costs. Apple says it will inspect the device before providing a final repair estimate.
