Recent videos have shown an iPhone 18 Pro becoming unresponsive, with symptoms including a flickering screen, overlapping interface elements, and a touchscreen that no longer responds. The issue has been attributed to a crash of **SpringBoard**, the iOS launcher responsible for managing the home screen, widgets, and system animations. This is described as a software bug in iOS 27, the update released on September 14. The bug is not new, with videos of the issue circulating on Reddit and X as early as September 16. The phenomenon has been nicknamed "BugOS 27," a term encompassing various visual glitches observed in the update. The crash does not occur during normal use and requires a specific sequence of gestures to reproduce. One widely shared method involves widgets in edit mode, where a widget is moved from one page to another by holding the side button. Another method involves quickly opening the notification center and then the control center, which 9to5Mac managed to freeze an iPhone using. Others have reported freezing the device by interacting with the Clock widget or page indicators at the bottom of the screen. However, not all users can reproduce the bug, including some on older models like the iPhone 15 Pro Max. No data loss has been reported, and in most cases, SpringBoard restarts on its own (a "respring"), or a forced restart restores everything to normal. The bug is not exclusive to the iPhone 18 Pro but is an issue with iOS 27, which could affect other iPhones running this version. The iPhone 18 Pro has received more reports due to it coming with iOS 27 from the factory and users customizing their home screens extensively right out of the box. Separately, there is another issue on the iPhone 18 Pro series related to Face ID. When Face ID fails in a protected app, such as Passwords or Safari private tabs, the smartphone freezes and restarts. Apple has confirmed a fix is coming, likely iOS 27.0.1, expected to be released on Monday, September 28, or Tuesday, September 29. This fix primarily targets the Face ID issue, and there is no indication it will also address the SpringBoard crash. Apple has not publicly commented on the SpringBoard bug. In the meantime, users experiencing a frozen iPhone can restart it by pressing the volume up button (short press), volume down button (short press), then holding the side button until the Apple logo appears. Users are advised to avoid interacting with widgets in edit mode to prevent triggering the issue. Despite these problems, the iPhone 18 Pro is described as a very good smartphone in recent tests.
