History

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.


Fire OS 5

Based on Android 5.1 "Lollipop", it added an updated interface. 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. It removed support for device encryption, which an Amazon spokesperson stated was an enterprise-oriented feature that was underused. In March 2016, after the removal was publicized and criticized in the wake of the FBI–Apple encryption dispute, Amazon announced it would restore the feature in a future patch.


Fire OS 6

Based on Android 7.1.2 "Nougat", its main changes and additions include: * Adoptable storage, allowing users to format and use their SD card as internal storage * Doze/App standby, aiming to improve battery life by forcing devices to sleep when not actively used, adding restrictions to apps that would normally continue to run background processes *


MediaTek exploits (2019)

In early 2019, security exploits for six Fire Tablet models and one Fire TV model were discovered that could allow temporary root access, permanent root access, and bootloader unlocking due to security vulnerabilities in multiple MediaTek chipsets.


Fire OS 7
