The iOS 27.0.1 update is out, and it fixes three real annoyances: Face ID restarts, a camera color glitch, and a frozen touchscreen. Apple released it on September 28, 2026, and you can install it now from Settings.
It adds no new features. It’s a short bug-fix patch, and for most people it’s worth installing today.
Quick Facts
- Released September 28, 2026 (build 24A446), about two weeks after iOS 27 launched.
- Works on every iPhone that can run iOS 27, plus a matching iPadOS 27.0.1.
- Fixes three bugs. Two are specific to iPhone 18 Pro and Pro Max.
- No new features and no feature changes.
The short version: if you own an iPhone 18 Pro or Pro Max, this one matters most.
What the iOS 27.0.1 update fixes
Apple’s release notes list three fixes. According to 9to5Mac and TechRepublic, here is what changed.
| Problem | Who it affected | What Apple says is fixed |
|---|---|---|
| Face ID restarts | iPhone 18 Pro and Pro Max | Phone no longer restarts when Face ID fails to authenticate |
| Camera color artifact | iPhone 18 Pro and Pro Max | Color glitch at 2x zoom in certain lighting at f/1.48 |
| Unresponsive touchscreen | All supported iPhones | Screen no longer locks up when Notification Center and Control Center open together |
The touchscreen fix is the one that reaches the most people, since it isn’t tied to a single model.
Why the Face ID fix matters most
A phone that restarts after a failed face scan is more than a nuisance. After a restart, you must enter your passcode before Face ID works again. That can happen at the worst moment, like paying at a checkout.
The restart bug hit the newest Pro models, which launched only weeks ago. If you’ve seen random reboots on an iPhone 18 Pro, this update is the first thing to try.
It’s not the only early issue on these phones. We’ve also covered the iPhone 18 Pro Max storage speed problem and the AT&T issue that needs a replacement.
How to install the iOS 27.0.1 update
The steps are the same as any iPhone update. Do a quick backup first, as Apple suggests.
- Connect to Wi-Fi and plug in your phone, or make sure the battery is above 50%.
- Open Settings, then General, then Software Update.
- Tap Update Now and wait for the restart.
The download is usually small for a point release, and the install takes about ten minutes. Keep the phone on the charger so it doesn’t die halfway through.
If you don’t see it yet, wait a few hours and check again. Rollouts can reach some phones later than others.
What iOS 27.0.1 doesn’t fix
Apple’s notes are short, and they only name three bugs. Anything else you’ve noticed since iOS 27 launched may still be there after you update.
That includes the storage speed complaints on the new Pro phones, which are a hardware and firmware question rather than a simple software bug. Don’t expect a patch this small to change benchmark numbers.
Apple also rarely lists every change in a point release. Some users find small extra fixes after updating, but you shouldn’t count on that.
If the update won’t install or problems continue
A few simple checks solve most update trouble. Work through them in this order.
- Free up space. Updates need several gigabytes of free storage, so delete unused apps or old videos first.
- Restart the phone, then check Software Update again.
- Try a different Wi-Fi network if the download stalls.
- Still seeing Face ID restarts after updating? Re-scan your face in Settings and, if it keeps happening, book a Genius Bar visit.
These steps cost nothing and take a few minutes. They also rule out a local problem before you blame the update.
What comes next after iOS 27.0.1
This patch is only a stopgap. The bigger update is iOS 27.1, which should bring actual new features. We’ve broken down what’s expected in iOS 27.1 if you want to plan ahead.
Apple’s notes for 27.0.1 don’t list security content, only “bug fixes for your iPhone.” For security patches, see our look at the iOS 27 security update.
Frequently Asked Questions
Is iOS 27.0.1 safe to install?
Yes. It’s a small maintenance release and no major problems have been reported with it so far. Back up first, as you would before any update.
Does iOS 27.0.1 fix battery drain?
Apple doesn’t mention battery life in the release notes. If battery drain started after updating to iOS 27, this patch isn’t promised to fix it.
Which iPhones get the iOS 27.0.1 update?
Every iPhone that can run iOS 27. The Face ID and camera fixes only matter on iPhone 18 Pro and Pro Max.
Can I go back to iOS 27.0 after updating?
Usually not. Apple stops signing older versions soon after a new one ships, so plan on staying on 27.0.1.
Should you update?
Yes, and don’t wait. A bug-fix patch with no new features carries little risk, and a frozen screen or surprise restart is the kind of bug that gets worse the longer you live with it. If you have an iPhone 18 Pro, do it today.
