Fire OS

Amazon has just announced Sangria, the next version of its mobile operating system Fire OS. Fire OS 4 "Sangria" is based on Android 4.4 KitKat and is launching with the just-announced Fire tablets. The latest OS version brings UI refinements (still focusing on Amazon's content), user profiles, Family Library content sharing and Firefly to all compatible devices.

Fire OS 4 comes pre-loaded on the latest Kindle Fire tablets, will hit third-generation Fire tablets as an over-the-air update in due course and the Fire Phone will get it early next year.

Press Release

Introducing Fire OS 4 "Sangria"

SEATTLE--(BUSINESS WIRE)--Sep. 17, 2014-- (NASDAQ: AMZN)—Amazon today introduced Fire OS 4 "Sangria," the next generation of software and services that powers Amazon's Fire devices, including the all-new Fire tablets introduced today.

"When we think about Fire OS, we start with what matters to customers—ease of use and performance," said Dave Limp, Senior Vice President, Amazon Devices. "Fire OS 4 improves in both of these areas, and deeply integrates software, content, and the Cloud to deliver services that are only available from Amazon, including Family Library, Firefly, and free cloud storage for photos."

The latest version of Fire OS, "Sangria," continues Fire OS' content-forward user interface that delivers easy and fast access to your favorite books, songs, videos, and games—open them with one tap rather than hunting through folders and apps. Fire OS 4 updates the visual design of the UI and adds Profiles so each family member can have their own individual email, Facebook and Twitter accounts, settings such as display brightness, bookmarks, spot in a movie, and game levels.

Fire OS 4 is based on KitKat and adds features and services to make it faster and easier to use. For example, Fire OS includes ASAP (Advanced Streaming and Prediction) which predicts the movies and TV episodes you'll want to watch and starts them instantly, and Smart Suspend develops a device-specific profile for when the tablet is typically not in use and proactively turns wireless off and on to deliver up to 25% more standby battery life.

Fire OS is not just a device OS—it deeply integrates with the Amazon cloud to further improve performance and ease-of-use, to enable cross-platform syncing, and to power services that require more processing than is possible on a mobile device. Examples of new cloud services in Fire OS 4 include Family Library so you can share your apps, games, audiobooks, books, and Prime Instant Video content with other members of your household; Firefly so you can identify and take action on artwork, text, and audio instantly—available for over 100 million items; and free unlimited storage in Cloud Drive for photos taken on Fire devices.

Fire OS 4 will be available on all 4th generation Fire tablets and will be available for all 3rd generation Fire tablets via a free, over-the-air software update. Firefly will be available on Fire HDX 8.9. Fire OS 4 will be available on Fire phone early next year.
