Fire OS is an Android-based operating system developed by Amazon for their hardware devices. Fire OS includes a customized user interface primarily centered on content consumption, and heavy ties to content available from Amazon's storefronts and services.{{Cite web |date=2023-03-01 |title=What is Fire OS?

History

{{See also|Fire HD#Software}}

Amazon began referring to the Android derivative as Fire OS with its third iteration of Fire tablets. Unlike previous Fire models, whose operating system was described as "based on" Android, Fire OS 3.0 was described as "compatible with" Android.{{Cite web |title=Fire OS Overview {{!}} Amazon Fire TV |url=https://developer.amazon.com/docs/fire-tv/fire-os-overview.html |access-date=2025-03-04 |website=developer.amazon.com}}

The home screen has a traditional application grid and pages for content types, as opposed to the previous carousel interface. It also introduced On Deck, a function that automatically moves content out of offline storage to maintain storage space for new content; the Word Runner speed reading tool; and screen color filters. Parental controls were enhanced with a new web browser for FreeTime mode featuring a curated selection of content appropriate for children, and an Activity Center for monitoring children's usage.{{cite web|title=What's new in Amazon Fire OS 5 Bellini?|url=http://www.pocket-lint.com/news/135336-what-s-new-in-amazon-fire-os-5-bellini|website=Pocket-lint|date=September 17, 2015 |access-date=January 28, 2016}}{{cite web|title=Amazon's Fire HD 10 tablet a rare misfire for company|url=http://fortune.com/2015/09/29/amazon-10-tablet-review/|website=Fortune|access-date=January 28, 2016}}{{cite web|title=Feature-stuffed Fire OS update makes Amazon's tablets even more kid-friendly|url=http://www.pcworld.com/article/3011171/tablets/feature-stuffed-fire-os-update-makes-amazons-tablets-even-more-kid-friendly.html|website=PC World|access-date=January 28, 2016}} It removed support for device encryption, which an Amazon spokesperson stated was an enterprise-oriented feature that was underused.

= Report of migrating away from Android =

Around November 2023, a report surfaced of Amazon's plans to migrate away from Android to a custom Linux-based operating system known as "Vega". Apps will be HTML5 based, specifically using React Native. Amazon was reported to be developing the operating system since 2017, and planning to launch TVs running Vega in 2024. It is unclear on whether existing Android-based Fire TV devices will get replaced with Vega.{{Cite web |last=Pandey |first=Rajesh |date=2023-11-10 |title=Amazon is getting ready to ditch Android on its Fire hardware |url=https://www.androidpolice.com/amazon-getting-ready-ditch-android-fire-hardware/ |access-date=2023-11-26 |website=Android Police |language=en}}{{Cite web |date=2023-11-09 |title=Amazon may drop Android and build its own next-gen smart home OS |url=https://www.androidauthority.com/amazon-android-alternative-3384275/ |access-date=2023-11-26 |website=Android Authority |language=en}}

Features

Fire OS is based on the Android Open Source Project (AOSP). It does not come with Google mobile services pre-installed; therefore, Amazon cannot use the Android trademarks to market the devices. Users are able to sideload the Google Play store;{{Cite web |title=How to Install the Google Play Store on the Amazon Fire Tablet or Fire HD 8 |url=https://www.howtogeek.com/232726/how-to-install-the-google-play-store-on-your-amazon-fire-tablet/ |access-date=March 3, 2021 |website=How-To Geek|date=November 23, 2017 }} however, full compatibility is not guaranteed if the app depends on Google services.{{cite web |last=Segan |first=Sascha |date=December 2013 |title=How To Run Free Android Apps On the Kindle Fire |url=https://www.pcmag.com/article2/0,2817,2396276,00.asp |website=PC Magazine}}

Because Google services are not pre-installed, Amazon develops and uses its own apps in their place, some of which include Amazon Appstore, Amazon Alexa, Prime Video, Amazon Music, Audible, Kindle Store, Silk Browser, Goodreads and Here WeGo.{{Cite web|url=https://www.lifewire.com/history-of-fire-os-4582380|title=Here's What You Need to Know About Amazon's Fire OS|website=Lifewire|access-date=March 3, 2021}}{{Cite web|url=https://computer.howstuffworks.com/tablets/kindle-fire.htm|title=How the Kindle Fire Works|date=August 22, 2012|website=HowStuffWorks|access-date=March 3, 2021}}

Fire OS uses a customized home screen (launcher). As of Fire OS 7.3.2.3, the launcher features three sections:{{Citation needed|date=February 2025}}

  • "For You" shows the weather, recently used apps, Alexa integration, then shows recommended content such as apps, books movies, etc.
  • "Home" is the section for the icons of all of the apps currently installed on the device, apps on the Home section can be moved around or put into folders, a search bar is also available at the top of the launcher to search though local content on the device or search online using the Bing search engine.
  • "Library" shows purchased items from Amazon services, such as apps, books, movies and TV shows from Prime Video, etc.

The OS features a multi-user system, which allows multiple people to set up and use separate user profiles.{{Cite web|url=https://www.androidauthority.com/profiles-amazon-fire-tablet-3233456/|title=How to add and switch profiles on an Amazon Fire tablet|website=Android Authority|access-date=March 19, 2023 |archive-url=https://archive.today/20230319211527/https://www.androidauthority.com/profiles-amazon-fire-tablet-3233456/ |archive-date=March 19, 2023 |url-status=live}}
