Remove ads
KaiOS is a mobile Linux distribution for keypad feature phones based on the Firefox OS open-source project.[6] It is developed by KaiOS Technologies (Hong Kong) Limited; a company based in Hong Kong, whose largest shareholder is Chinese electronics conglomerate TCL Corporation.[7][1] KaiOS runs on feature phones or wireless home phones made with low-power hardware and low power consumption (and therefore long battery life).

Overview and features
KaiOS supports modern connectivity technologies like 4G LTE, VoLTE, GPS, and Wi-Fi. KaiOS runs HTML5-based apps, supports over-the-air updates, and has a dedicated app marketplace called KaiStore.[8] Some applications are preinstalled onto the phone, including Facebook and YouTube.[9] As of 1 April 2020[update], there are 500+ apps in KaiStore.
The mobile operating system is comparatively lightweight on hardware resource usage, and is able to run on devices with just 256 megabytes (MB) of memory.[10]

History

Perspective
The operating system was first released in 2017, and is developed by KaiOS Technologies Inc., a Hong Kong–based[11] company headed by CEO Sebastien Codeville, with offices in other countries. In June 2018, Google invested US$22 million in the operating system.[12] That same year, India-based telecom operator Reliance Jio also invested $7 million through its sister concern, Reliance Retail for a 16% stake in the company.[13][14] In May 2019, KaiOS raised an additional $50 million USD from Cathay Innovation, and previous investors Google and TCL Holdings.[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 the popularity of the competitively-priced JioPhone.[17] In Q1 2018, 23 million KaiOS devices were produced.[18]
As of February 2018[update], KaiOS Technologies has partnered with Mozilla, Airfind, Avenir Telecom (Energizer), Facebook, Google, Bullitt, Doro, HMD Global, Micromax, NXP, Spreadtrum, Qualcomm, Jio, Sprint, AT&T, T-Mobile, and Orange S.A.[19][9][20]
In March 2020, Mozilla and KaiOS Technologies announced a partnership to update KaiOS with a modern version of the Gecko browser engine, and more closely aligned testing infrastructure. This change should give KaiOS four years worth of performance and security improvements and new features, including TLS 1.3, WebAssembly, WebGL 2.0, Progressive Web Apps, new video codecs like WebP, AV1, and modern JavaScript and Cascading Style Sheets (CSS) features.[21][22]

Jailbreak
With the release of the Nokia 8110 4G, an active community (colloquially known as Banana Hackers) around both KaiOS and the phone arose and released the first version of a jailbreak. This gave users the ability to use apps outside KaiStore including old Firefox OS apps on KaiOS devices, as well as flashing their devices with community-created ROMs, such as GerdaOS.[54][55]
Some models can also be rooted, giving the user further control over the device.[56]
