iOS 27.0.1 Fixes Three Confirmed Bugs, but Some Users Still Report Touchscreen Issues
The September 28 update fixes a Face ID restart and camera colour bug on the iPhone 18 Pro and a touchscreen freeze on all iPhones. Wider performance complaints remain unexplained.

Apple released iOS 27.0.1 on September 28, two weeks after iOS 27, with fixes for three specific bugs. It stops short of resolving a broader wave of touchscreen and performance complaints that users have posted on Reddit and Apple's support forums since iOS 27 shipped (MacRumors, TechRepublic).
What iOS 27.0.1 fixes
| Bug | Devices |
|---|---|
| Unexpected restart after a failed Face ID attempt | iPhone 18 Pro and Pro Max |
| Camera colour artifact | Some iPhone 18 Pro models |
| Touchscreen stops responding when Notification Center and Control Center are opened together | Any iPhone on iOS 27 |
Apple released iPadOS 27.0.1 at the same time, and its notes say the fixes target exactly these problems rather than iOS 27 issues more broadly. The release notes did not mention cellular fixes, which became relevant when AT&T urged iPhone 18 Pro Max owners to install the update.
What is still being reported
Threads on Reddit and other forums describe touchscreen and performance problems that do not match the Notification Center and Control Center trigger Apple fixed: screens becoming unresponsive in seemingly random parts of the interface, and slow or jittery performance when swiping between screens or switching apps. An iPhone 17 Pro Max owner described frame-rate drops in apps including Reddit, WhatsApp and Wallet. A separate Home Screen freeze when editing widgets, usually while dragging a widget between pages, has also been reported after 27.0.1 (Tech Between the Lines).
Some users have reported battery drain and overheating on models including the iPhone Air and iPhone 15 Pro Max, and a smaller number of iPhone 18 owners say their phones restarted during Face ID, Apple Pay transactions or calls, distinct from the bug Apple fixed. Apple has not confirmed a cause or a timeline, and forum reports are not a reliable sample of the whole user base.
Why some of this may settle down
Performance and battery irregularities in the days after a major iOS update are common while the phone re-indexes data in the background, so some complaints may ease without a further update. For an unresponsive screen, users report that a full restart helps temporarily, and one guide suggests a force restart before installing 27.0.1.
For Indian buyers
The iOS 27 rollout and the 27.0.1 fix are the same in India as elsewhere. Indian owners of the newly launched iPhone 18 Pro and Pro Max affected by the Face ID restart should install 27.0.1.
What to watch next
No iOS 27.0.2 or 27.1 has been reported. The next release appears to be iOS 27.2, which one guide says reached release candidate on October 19, and it will show whether Apple addresses the broader touchscreen and performance complaints.
