Nokia 8110 4G

KaiOS is a mobileoperating system based on Linux, owned by KaiOS Technologies, a US-based company.[3] It is forked from B2G OS (Boot to Gecko OS), an open source community-driven fork of Firefox OS, which was discontinued by Mozilla in 2016.[4][5][6]

The primary features of KaiOS bring support for 4G LTE E, VoLTE, GPS and Wi-Fi with HTML5-based apps and longer battery life to non-touch devices with optimized user interface, less memory and energy consumption.[7][8] It also features over-the-air updates.[citation needed] A dedicated app marketplace called KaiStore enables users to download applications.[9] Some services are preloaded as HTML5 applications, including Twitter, Facebook and YouTube.[10] The operating system is comparatively lightweight on hardware resource usage, and is able to run on devices with just 256 MB of memory.[11]

The operating system first appeared in 2017 and is developed by KaiOS Technologies Inc., a San Diego, California-based company headed by CEO Sebastien Codeville with offices in other countries.[12][13] In June 2018, Google invested US$22 million in the operating system.[14]India-based telecom operator Reliance Jio also invested $7 million in cash to pick up a 16% stake in the company.[15]

In market share study results announced in May 2018, KaiOS beat Apple's iOS for second place in India,[16] while Android dominates with 71%, albeit down by 9%. KaiOS growth is being largely attributed to popularity of the competitively-priced Jio Phone.[17]

In Q1 2018, 23 million KaiOS devices were shipped.[18]

Open source[edit]

With the release of the Nokia 8110 4G, an active community around both KaiOS and the phone arose and released the first version of a jailbreak. This gave users the ability to use old Firefox OS apps on KaiOS devices, as well as flashing their devices with community-created ROMs, such as GerdaOS.


As of February 2018, KaiOS Technologies has partnered with Airfind, Facebook, Google, Twitter, Bullitt, Doro, HMD Global, Micromax, NXP, Spreadtrum, Qualcomm, Jio, Sprint, AT&T, T-Mobile, and Orange S.A.[39][10]
