Facebook Home, Facebook’s attempt to make your Android homescreen all about Facebook, is now live in the Google Play Store.

As of right now, you can only download Facebook Home if you have one of these four Android devices: HTC One X, HTC One X+, the Samsung Galaxy S III or the Samsung Galaxy Note II. In the future, the HTC One and the Samsung Galaxy S4 will also allow for Facebook Home.

And then, of course, there’s the HTC First – the first phone to launch with Facebook Home ready to go. Don’t want to call it a “Facebook Phone” – then don’t. But it’s definitely the first Facebook centric phone on the market. It also hits the shelves today.

“Facebook Home is the mobile experience that puts your friends at the heart of your phone. From the moment you turn it on, you see a steady stream of friends’ posts and photos on your home screen. Upfront notifications and quick access to your essentials mean you’ll never miss a moment. And when you download Facebook Messenger, you can keep chatting with friends when you’re using other apps,” says Facebook.

And about those chat heads that let you “keep chatting with friends when you’re using other apps.” If you have an Android phone, want to download Facebook Home, but alas, your Android phone isn’t supported – all is not lost. Today, ahead of the Facebook Home launch, Facebook added chat heads as a part of the Facebook Messenger app for Android. Now you can make use of/be incredibly annoyed by chat heads no matter which Android device you own, depending on how you look at it.
