Comparing sweets: Android Lollipop vs. Android KitKat

Android Lollipop brings Google's OS version up a full integer, as 5.0 is packed with a serious load of changes.

The most obvious of the changes are the visual enhancements to the UI. Google has maintained the flat look from Android KitKat but also adds in some punch with real time shadows and animation to give Lollipop more depth and dynamic. Google is calling this realistic new look "Material Design."

From icons to navigation buttons, notification bars, fonts, and other design elements, Material Design is meant to make Android's look more unified and give developers more ways to have creative visualization in their apps.

Even more than aesthetics, Android Lollipop also packs in a lot of upgrades under the hood.
