Updated on October 17 with additional responses to the new security features absent in the Pixel 9’s Android 15 release, and the mistake in the run-up to that release.

Android 15 introduces a completely new design to the expanded Android volume panel on Pixels — with larger, more easily adjusted sliders for specific sorts of media volumes as well as a more prominent button to shift your phone’s audio output from the phone itself to any connected devices.

The October patch fixes a lot for Pixel phones, beginning with battery issues plaguing the Pixel 6 series. Google states this fix aims to solve those devices "occasionally" rebooting. Moreover, charging enhancements and battery usage updates have arrived for the Pixel 7, Pixel 8, and Pixel 9 series.
