Waze 4.0 is on the way to Android soon, and with it comes a complete overhaul of the entire app's interface. Everything, and I mean everything, has been touched by this update. The app is still clearly recognizable as Waze, but definitely a much slicker, more animated Waze. I wouldn't call it "material" by any means, but it's certainly a lot more modern than what Waze is shipping right now. Take a look at these two GIFs for examples of just what I mean - even the traffic flow animation is now snazzier. There's also this fun little loading bar any time you start a route that shows potential obstacles and traffic on your way.
