“We’re not building a phone, we’re not building an operating system. But we’re building more than just an app," Zuckerberg said. Facebook Home, which can be downloaded beginning on April 12, encompasses a range of features and allows users to easily switch between conversations with friends and apps.
The Home screen involves a small image of the user at the bottom of the screen. From here the user can swipe this icon upwards leading to a page of app downloads, making it easy to access other apps on the user’s phone. The main feature of Home is Chatheads, which allows users to easily switch between SMS and Facebook Message conversations and other apps. “We wanted this to feel like system software rather than an app you install,” said Zuckerberg.
"We think that Chatheads are this great, personal way to do messaging," Zuckerberg said.
Adam Mosseri, Facebook product designer, then took to the floor to demonstrate the feature, saying that it would personalize people's phones better: "What we're trying to do is shift people's focus away from tasks and apps and toward people."
The app can be downloaded from the Play store.
