We don’t know how many of you out there have the Android M preview installed, but if you do, this could be our first public taste of what Google Now On Tap will do for us once Android 6.0 Marshmallow comes around. This is all wrapped inside an update to the Google app, version 5.3 for Android 4.4 or above.
You will need developer preview 3 to get Now on Tap to not crash on start and even then, you will have to deal with the developer previews being developer previews. Bug reports ahoy! But all you have to do to get more info on what’s on-screen is to hold the home button for a bit. Also, check out the Google Now Launcher aesthetic shift to a vertical-scroll app drawer and widget list along with a most recents tab.
