Just now iFixit published a disassembly report of the iPhone 13 series to show the changes in the internal structure and also found an unexpected bug. Although Apple has separated the Face ID components from the screen, if the iPhone 13 is replaced with a screen, the Face ID on it cannot be used. The iFixit team also tried various feasible methods, but they all seemed to be locked. According to the report, this may be a bug.
Because iFixit quoted a qualified repairer authorized by Apple as saying that the official has actually found the problem and will fix it in future iOS updates. In particular, overseas awareness of the maintenance rights and interests of electronic products is increasing, so Apple should be just a bug, otherwise it may trigger a new round of condemnation and even attract the attention of consumer rights organizations.
