● The app drawer now takes over the entire screen when tapped with a plain black background and a persistent home button at the bottom of the screen to return you to the home screen. Animations are added to the app drawer, a theme throughout Android 2.1, which shows app icons bending off the screen at the top and bottom when the user is scrolling

● This is the first version of Android under the design direction of Matías Duarte and the first to share a cohesive look known as Holo (holographic) across the operating system and apps.
● Notably, Android 3.0 is designed for tablets only, which left Google free to design with a significantly larger screen in mind.
