Looking at a bunch of gibberish? Maybe just at your home screen? Perhaps you don’t have the Google Now Launcher, but you want to hit up Google Now. On phones with hardware navigation keys, you can’t just pull up Google Now from the home button.
Well, if you have Now on Tap, you’ll have access to Google Now cards if there’s “nothing to show”. No search terms, no people, no information to pick up and let you look at.
Now, what’d be cool is if even when you have search entries to look at is if the Google Now cards would appear in that case, too. If you’re not of mind to go home before you get on tap, it’d be a bit more convenient. But if you want to drop in on the Google app beta to get the update, you’re welcome to do so.
