iPhone 18 Pro Face ID Reboot Fix Is Coming

An iPhone 18 Pro Face ID reboot bug has a fix on the way. According to a September 24 report, Apple plans a software update early next week for some iPhone 18 Pro and Pro Max phones that restart after Face ID fails while opening a protected app. Apple has not publicly named the update version.

What triggers the iPhone 18 Pro Face ID reboot

The reported pattern is specific. A user tries to open an app that requires Face ID. If authentication fails, the phone can unexpectedly restart instead of returning to the app. The issue does not appear to affect every new Pro model, and the report does not establish how often it happens.

9to5Mac reported on September 24 that Apple expects to deliver a fix early next week. The outlet suggests iOS 27.0.1 as a likely version number, but Apple has not confirmed that label. Treat the timing as a plan until the update appears in Software Update.

What to do before the fix arrives

If your phone has not shown this behavior, you do not need to change how you use Face ID. If it has restarted, start with a current backup. A backup gives you a safer position before any software update or support visit. It will not fix the restart by itself.

Check for the official update

Open Settings, then General, then Software Update when Apple releases the fix. Install only an update that appears through Apple’s normal channel. The version could differ from the one people expect today. Keep the phone charged and connected to a reliable network while it installs.

Keep a short record of the issue

Note which app was protected, whether Face ID failed, and whether the phone restarted right away. Avoid repeated attempts just to reproduce the bug. If restarts happen in other situations, contact Apple Support rather than assuming they share the same cause.

What remains unknown

Apple has not listed the affected device count or explained the underlying fault. The report also does not promise that every restart on an iPhone 18 Pro will disappear with this fix. A separate battery, app or hardware problem could produce similar symptoms, so the trigger matters.

The immediate story is a targeted fix for a current problem, not a broad new iOS feature. If you are reviewing your phone’s safeguards while waiting, our Stolen Device Protection guide explains a separate feature that uses biometric checks. Back up an affected phone, watch Software Update next week and contact Apple Support if the behavior extends beyond failed Face ID in protected apps.
