Allo was supposed to be the app the finally unified messaging in Android, but it hasn’t actually worked out that way. However, Google keeps plugging away at it. Along with recent improvements like an Assistant shortcut and new animated emoji, Google has also added a new feature in its latest Allo update: Android Auto support.
It’s hard to believe Google waited this long to build hands-free support for its newest messaging apps, but Allo messages never actually appeared on the main Android Auto screen. Now Allo users who use Android Auto in their cars will be able to hear and respond to Allo messages just as if they were coming in from Hangouts or Android Messages. When a new message arrives, you’ll be able to see the sender on the screen, play it, or select a prewritten response to send.
