There's a Google Maps beta channel on the Play Store now, and you can sign up for it at this link. You can also download the new APK, version 9.27, directly from APK Mirror if you prefer, right here.

We're still rooting around in the app to see if there's anything new, so let us know if you find anything! (Remember, Maps was also updated last week to v9.26.1, so anything from that update is not new). Also remember that if you're running the Android N preview, you already have Maps 9.30, and so this 9.27 APK will not install over your existing app, as it's a newer version.

Thanks: Tom & Deana Green
