Android 8.1 Oreo is currently the most stable version of the Linux -
based Android mobile OS, bringing several enhancements and new features like a slightly transparent Quick Settings menu, light and dark themes that turn on
automatically based on
home screen's wallpaper, a Google Search bar under the dock, and a new «
At a Glance» widget on top of the Calendar and Weather info.
Whereas you can have your Echo or Google
Home automatically switch between music accounts or calendars
based on who is asking a question,
at launch HomePod will only be able to pull up information
based on the account of the person who first set it up.
