Apple published its iOS 27.0.1 update notes on September 29, 2026, listing three fixes. Separately, a user-reported iOS 27 issue involves moving the Clock widget over a group of apps while rearranging the Home Screen. The reported symptoms include a black on-screen element, flickering, and an iPhone that freezes and restarts or needs a restart.
Apple's iOS 27.0.1 notes list three fixes
Apple lists three issues addressed in iOS 27.0.1:
- Unexpected restarts: iPhone 18 Pro and iPhone 18 Pro Max may restart unexpectedly when Face ID fails to authenticate.
- Camera color artifact: 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 iPhone 18 Pro Max devices.
- Unresponsive touchscreen: The touchscreen may stop responding if Notification Center and Control Center are opened at the same time.
What the Clock-widget report describes
In the reported sequence, moving the Clock widget over a group of apps during Home Screen rearrangement is followed by a black on-screen element and repeated flickering. The iPhone then becomes unresponsive and restarts, or needs to be restarted.
One user reportedly reproduced the behavior on an iPhone 16 Pro Max running iOS 27. In that account, restarting the iPhone restored normal operation.
The reported restart triggers are different
Apple's listed Face ID-related restart issue applies to iPhone 18 Pro and iPhone 18 Pro Max and has a different trigger from the Clock-widget interaction. A separate user account describes another Home Screen crash while moving widgets between pages and holding the power/wake button.
