A Weibo user named Kang shared a video, pointing out that the section above the hinge on the inner screen of the iPhone Duo has a soft feel. When pressed, it sinks in and might show temporary wrinkles. Once the finger is removed, the screen reverts to its smooth state. Several devices display this same issue. However, at present, this observation is solely derived from user tests and social media posts. Independent durability tests have not been conducted yet, making it impossible to ascertain whether there is a defect in the device.
