Some of the folks over at WebmasterWorld are noticing a new referrer coming from Google that comes from the string com.google.android.googlequicksearchbox.
Interestingly, that is the name of the Android app APK for the Google Search app on Android, see https://play.google.com/store/apps/details?id=com.google.android.googlequicksearchbox&hl=en.
Maybe Google is starting to show webmasters that their search referrers are coming specifically from the Android Google app?

I see it starting around 27th April, from Android devices, naturally. From the actual referrer, my guess would be a link from the default Google search bar on a device (this opens in the Google app rather than in a browser). This is installed by default on most devices, I believe.According to the Play Store [play.google.com], the app updated on April 28th, too.
