Cover feed replaces the lock screen and home screen. It's a window into what's happening with your friends - friends finishing a bike race, your family sharing a meal or an article about your favorite sports team. These are the beautiful, immersive experiences that you get through Home.
You might have missed these updates before, but now they're a central part of the Home experience. Since Home is both your lock screen and home screen, the content comes right to you. You can flip through to see more stories, and double tap to like what you see.
With chat heads you can keep chatting with friends even when you're using other apps. When friends send you messages, a chat head appears with your friend's face, so you see exactly who you're chatting with. Messages reach you no matter what you're doing - whether you're checking email, browsing the web, or listening to music.
You can move chat heads around and respond to messages. And since SMS is integrated into Facebook Messenger for Android, chat heads include Facebook messages as well as texts.
When something happens that's more important and directed at you, like a friend posting on your timeline, you'll receive notifications with their profile pictures. To open notifications, just tap them. And if you don't want to deal with them right now, you can just swipe to hide them and keep flipping through cover feed until you want them back.
It's as easy to get to your apps in Home as it is on any other phone. Swipe up to see your favorite apps in the launcher. There's also a screen containing all of your apps, and you can drag your favorite apps to the launcher.
Home will be available as a free download from the Google Play Store starting April 12. It works on the HTC One X, HTC One X+, Samsung GALAXY S III and Samsung GALAXY Note II. Home will also work on the forthcoming HTC One and Samsung GALAXY S4, and on more devices in the coming months.
Home will also be available pre-installed on phones through the Facebook Home Program. HTC and AT&T are the first companies working together to deliver a phone with Home. It's called the HTC First and it goes on sale April 12.
