Apple released iOS 27.0.1 on September 28, and the first line of its release notes is the bug owners have been reporting since the iPhone 18 Pro went on sale: the phone restarting when Face ID fails to authenticate. Two more fixes ship with it — a colour artifact in 2x photos and a touchscreen that stops responding when two panels are opened at once. There is no security content in this update at all.

What was announced

Apple's own update notes list three fixes in iOS 27.0.1, and the first is worded exactly as the fault people described: iPhone 18 Pro and iPhone 18 Pro Max may unexpectedly restart when Face ID fails to authenticate.

The second covers the camera — a colour artifact may appear on photos captured at 2x under certain lighting conditions at f/1.48, on what Apple calls a small number of iPhone 18 Pro and Pro Max devices. The third is a system fault with no model limit attached: opening Notification Center and Control Center at the same time may leave the touchscreen unresponsive.

Apple's security-updates page dates the release to September 28 for iPhone 11 and later, along with the equivalent iPads, and states that the update has no published CVE entries — so this is a bug-fix release with no security patches in it. The same day brought watchOS 27.0.1, visionOS 27.0.1 and a macOS 27.0.1.

We reported the restart fault on September 22, when owners were describing a failed Face ID attempt inside a locked app freezing the phone and rebooting it, with crash logs pointing at kernel panics. Apple has now named the fault in writing, which is the first acknowledgement of it.

What it means for players

Six days from the first wave of reports to a shipped fix is fast for a fault of this kind, and the wording matters as much as the speed. Apple is not describing a workaround or a setting — it lists the restart as a bug fixed in this build.

What the notes do not say is what caused it, or whether every case is covered. The description is narrow: a restart when Face ID fails to authenticate. Anyone whose phone was rebooting for a different reason has no promise here, and the release carries no security fixes to sweeten the update for people who like to wait.

The touchscreen fix is the quiet one worth having. It is not tied to a specific model in Apple's wording, which suggests it affects the wider iOS 27 install base rather than only this year's phones.

What happens next

The update is out now, over the air in Settings, and there is no reason for an iPhone 18 Pro owner to defer it — no security content means no trade-off to weigh, and the fix list is short and specific.

The open question is the Apple Watch side. Series 12 and Ultra 4 owners were separately reporting Neural Engine timeouts when the phone fault surfaced, and watchOS 27.0.1 shipped the same day without Apple publishing a fix list to match.

Frequently asked questions

1

What does iOS 27.0.1 fix?

Three things, in Apple's wording: iPhone 18 Pro and Pro Max restarting when Face ID fails to authenticate, a colour artifact in photos taken at 2x at f/1.48 on a small number of those phones, and an unresponsive touchscreen after opening Notification Center and Control Center together.

2

Does the update include security fixes?

No. Apple's security-updates page states that iOS 27.0.1 and iPadOS 27.0.1 have no published CVE entries, which means this build is bug fixes only. It was released on September 28 for iPhone 11 and later.

3

Was the Face ID restart bug ever acknowledged before?

Not in writing. Owners began reporting it days after the iPhone 18 Pro went on sale, and crash logs pointed at kernel panics. The release notes for this update are the first time Apple has named the fault itself.
