There are a variety of ways to Solid content from your phone to smart devices. The most helpful is when developers integrate the Cast SDK so that controls are built right into the audio or video app. Mirroring your device is another answer, and Google Home 2.14.1 adds shortcuts to make that more apparent.
Updating to the latest version of Google Home for Android, visiting a Smart Display or speaker’s Now Playing screen will reveal a new “Cast my audio” or “Cast my screen” pill at the bottom of the page.
This opens a prompt that explains the existing “Cast to mirror device” capability, with Google warning how your “system isn’t optimized for casting, so your experience could vary.” On Android 10, you’ll see one other system-level warning before previous to stream any internal device audio or visuals.
In previous versions of the Google Home app, “Mirror device” was solely positioned in the “Account” tab. That menu item remains to be present; however, the new Now Playing shortcut is far more convenient and likely to be noticed by users.
Google can also be testing a small tweak where “Add” is now not a shortcut alongside Call Home, Broadcast, and Routines. Instead, it’s in the top-left nook of the app. This minor change helps declutter the row of colorful icons; however, it’s not but fully rolled out. Google Home 2.14.1 for Android is widely available within the Play Store this afternoon.
