If you are looking for a pure Android experience, the official Google Now Launcher shears away anything the manufacturer has added with clean, minimalist results and Google Now features. The updated version brings Material Design look on non-Lollipop phones running Android 4.1 through 4.4.
To get Lollipop’s Material Design look on any phone, just update the Google Now Launcher and Google app to newest version. Though you will not get all the features the real Lollipop brings, it can help to give your phone a Lollipop feel. The launcher supports all phones running on Android 4.1 through 4.4.
If your default launcher is not Google Now Launcher, just install it from Play Store [Download] and activate it. You will get the solid white Google search bar, improved animations and a slide-out panel in Google Now.
For your information, the first and most dramatic change you will notice when you start up your Android 5.0 Lollipop device is its Material Design appearance. It combines bold colors, depth effects, animations and on-the-fly responsiveness to fit any screen size and display ratio.
