Pixel phones are getting a refreshed user interface, along with new ringtones, alarms, and notification sounds.

Google also updated the User Interface of the Sounds app for its Pixel handset.
In the Ringtones menu, users can choose from 12 categories, including Pixel Sounds. Each category provides a list of ringtones to preview. After selecting a ringtone, tap Done in the upper right corner.
The Sound & vibration menu also allows volume adjustments for Media, Calls, Ringtones, Notifications, and Alarms. Users can also adjust vibration intensity for calls, notifications, and alarms. This section also provides access to Now Playing, a feature that identifies songs playing nearby and displays them on the lock screen. Users can also view a history of songs identified by Now Playing.
