We are not exactly sure why Google removed the bubble buttons option from Google Maps, but they have returned in an update that should be available to you all in the market right now. Along with those quick calling and navigation buttons, we also get new transit goodies. If you are in a city that supports transit navigation, you’ll find ringtone/notification settings and tablet support. Another solid update for one of the greatest apps ever invented. Seriously, what would we do without Google Maps?
