As noted by MacRumors, the iOS 15.7.1 Release Candidate made available earlier this week appears to prevent Face ID from working on at least some iPhones.
According to user reports across Reddit and Twitter. Affected devices include iPhone 12 Pro and iPhone 13 Pro models at a minimum, but it is quite possible that other models are impacted too.
Affected users who attempt to reset Face ID on their iPhone receive a “Face ID Is Not Available” error, resulting in facial recognition being completely broken. According to MacRumors, “it’s unclear what the cause of the issue is or whether Apple is aware of the problem.”
