On September 28, 2026, Apple released iOS 27.0.1. It is the update that our earlier piece on the iPhone 18 Pro reboot bug said Apple had promised for the week of September 28. What changed since that piece: the promise is now a shipped build, and Apple named the Face ID restart in its own release notes. If you own an iPhone 18 Pro or Pro Max, install it.
What Apple says it fixes
As MacRumors reports from Apple's release notes, the update lists three fixes:
- The iPhone 18 Pro and iPhone 18 Pro Max may unexpectedly restart when Face ID fails to authenticate.
- A color artifact may appear in photos taken at 2x under certain lighting conditions at f/1.48, on a small number of iPhone 18 Pro and Pro Max units.
- Opening Notification Center and Control Center at the same time may leave the touchscreen unresponsive.
The first is the one that matters for this site's earlier piece. Apple has not said what was failing in the code, and the release notes do not either, so the explanation in the earlier piece about the Face ID sensor remains a guess. The second is a camera issue Apple describes as affecting a small number of units. That is Apple's wording; nobody outside Apple has published a share. In the coverage I found, the third fix is not tied to a specific model, so it may matter to other iPhones too, but I could not confirm that from Apple's text itself.
Who can install it
Apple's security releases page lists iOS 27.0.1 for the iPhone 11 and later, dated September 28, and says the update has no published CVE entries. So it is not a security patch. There is no urgency for an older iPhone on that account, but it is a normal point release and it installs like one: Settings, General, Software Update.
MacRumors also reports that Apple shipped iOS 26.7.1 the same day. That is the option for anyone who has stayed on iOS 26 and not moved to iOS 27, which arrived on September 14. I did not open the iOS 26.7.1 notes, so I cannot say what is in them.
What to check after installing
The advice in the earlier piece, before the update, was to use the passcode instead of retrying a failed Face ID scan. With the fix installed there is no reason to keep avoiding Face ID, but one honest caveat applies: a single point release does not prove a bug is gone. The earlier bug was intermittent, tied to failed scans rather than to everyday use, so a week without a restart is a better test than one clean unlock.
If your phone still freezes and restarts after failed scans on 27.0.1, that is a new fact, and it is worth taking to Apple Support with the software version in hand. The force restart from the earlier piece still works: volume up, volume down, then hold the side button until the Apple logo appears.
For the iPhone you already own
If it is not an iPhone 18 Pro, almost nothing changes. The two named fixes are specific to the Pro models. Install the update when it appears, as you would any point release, and do not expect a new feature.
If you own an 18 Pro and were wondering whether the reboot bug was a reason to return it: the fix arrived inside the window Apple gave, which is what a software bug looks like, as opposed to a hardware fault. Whether it holds is what the next few weeks will show. It is not something a release note can tell you yet.
Launch-week fixes like this one are a pattern this month: the Pixel lock screen bug had no official patch as of the last coverage I found, so the comparison with Apple's quick turnaround is real but partial. For what else the 18 Pro changed beyond this bug, read what actually changed on the iPhone 18 Pro.
