Following the release of the Android 16 system update, a subset of Pixel users has reported encountering significant issues with gesture operations and navigation functions. These issues manifest as delayed or completely non-responsive actions when using the back button and performing various gestures. The problem spans multiple generations of Pixel models, including the Pixel 8, Pixel 9 Pro XL, and Pixel 6. Notably, not all users are experiencing these issues. At present, Google has yet to issue an official statement concerning this matter, but it is anticipated that the company will swiftly investigate and roll out a corrective update to address these critical user experience concerns.
