Affected devices include at least iPhone 12 Pro 和 iPhone 13 Pro、iPhone 13 Pro Maxand other models.
To this end, some netizens reminded on social platforms: Do not update iOS 15.7.1.According to feedback from affected users, when they try to reset Face ID on their iPhone, they receive“Face ID not available”, which makes the facial recognition function unavailable. It’s unclear what caused the problem or if Apple was aware of it.
RC version refers to“Release Candidate”, which is neither a beta nor a GM (“Golden Master”) version. Chinese meaning “candidate release version”, also known as quasi-official version. Under normal circumstances, the RC version is the same as the update content of the official version of iOS.
