Android has had native screenshots for ages now, and seeing as that’s a pretty important feature, all of the Google-made accessories also support this functionality. While the setting is in an easy place on Android Wear, it’s well-hidden on Android Auto. Here’s how to find it.
The first thing you’ll need to do is enable Developer Settings in the Android Auto app by tapping on the “Android Auto” text on the top 10 times. For a more detailed look at Developer Settings, head here.
Once the Developer Settings menu has been enabled, jump in by tapping the three-button overflow menu in the top right corner and selecting “Developer Settings.”
There are some interesting entries found here, but the one we’re most interested in is “Share screenshot now.” Go ahead and give that tap. It probably goes without saying, but I’m going to say it anyway: your phone has to be connected to an Android Auto head unit before this will work.
Once you take a screenshot, the share dialog will pop up immediately, and you can send it wherever you like. But if you choose not to share it, the shot will just be saved to the root of the Pictures folder, so you can just share it later. That’s pretty neat. For simplicity, however, I just upload it to a dedicated screenshots folder in Drive.
And that’s pretty much it. Of course, you should never do this while you’re driving—if there’s something that important on the screen, pull over and take a picture. Otherwise, just let it go, man. It’s not worth it.
