Google has updated its Maps application for Android with support for Program-in-Picture (PiP); however, the feature is currently only available on (the handful of) smartphones running Android 8.0 Oreo.
Just like you’d minimise a channel using PiP on a TV, Maps allows you to shrink a navigation window, so you can actively monitor it from within any other application, like Play Music and Spotify.
Big G is distributing the release in stages
In typical fashion, Big G is distributing the upgrade in stages. From what we can tell, it’s currently live in the United States and a handful of countries in mainland Asia and Europe.
