Amazon announced that Fire OS 3.1, a free software update for the new Kindle Fire HD and Kindle Fire HDX, is now available. This free, over-the-air update will be delivered automatically in the coming weeks, or you can visit amazon.com/kindlesoftwareupdates to download and install the update.
Fire OS 3.1 brings deep integration with Goodreads, making it easier to find great books and have engaged discussions about them. For the first time, Goodreads is integrated directly into the reading experience, so there's no need to leave a book and open a Goodreads app.
Second Screen turns your TV into the primary screen and frees up your Fire HDX to provide playback controls, a customized display for X-Ray, or simply a place to email, browse the web, and more while you watch a movie. Second Screen is available for PlayStation 3 and Samsung TVs, and will be available later this year for PlayStation 4.
Fire OS 3.1 delivers the ability to connect to secure enterprise Wi-Fi networks and access corporate apps, documents, and resources like SharePoint; native VPN client for instant access to corporate networks; and a native SCEP (Simple Certificate Exchange Protocol) client to retrieve digital certificates for secure resources.
