There was much discussion around the changes Google introduced in Android Lollipop to the volume system, and more specifically the volume slider, but putting the confusing system aside, the slider animation itself wasn’t a great experience.
It appears that Google has changed the way things work in the latest Android Marshmallow Developer Preview and now when users hit a volume key, the panel slides into view. The expand icon now does just that and has a full transition from up to down with the rest of the slider folding out.
It seems Google is taking their own guidance, finally.
Just as the shape of an object indicates how it might behave, watching an object move demonstrates whether it’s light, heavy, flexible, rigid, small or large. In the world of material design, motion describes spatial relationships, functionality, and intention with beauty and fluidity.
It’s the small things that please us, hey Google.
