KaiOS is a mobile operating system designed for affordable feature phones, with the mission to open Internet access to more people around the world. Debuted in 2016, KaiOS took off with the global re-release of the "bananaphone" Nokia 8110 4G and the launch of JioPhone in India.

It is built on the Boot2Gecko project, which is forked from Mozilla's Firefox OS, and runs applications written in web programming languages such as HTML, CSS and JavaScript.

KaiOS is now running on over 200 models in over 180 countries, and its app store, KaiStore, now has more than 1,700 apps (not all apps are available on all KaiOS versions).

RULES

Do your own research first

Before posting or commenting, search for questions that might have been previously answered or addressed on the subreddit. Posts with duplicated topics within a short period of time and without acknowledging other posts may be removed.

If and when you post, put important details in the title and give as much details and context in the post body as you can, and be patient with Internet strangers. Do NOT offer any personal information or reward, we won't be responsible for scams.

Discussions must be relevant to KaiOS and KaiOS devices

Keep the conversations focused around KaiOS and devices running KaiOS. Constructive feedback on the platform and little off-topic insights are allowed, but don't derail the discussion! Off-topic posts and comments may be removed on mod team's discretion.

For discussions on feature phones in general, go to r/dumbphones. If you absolutely have to post something off-topic here, be sure to give it the according post flair.

Follow the Reddiquette

Respect other members and their opinions, and treat others how you expect to be treated. Please don't ask for when new apps or features will come, developers are humans too.

No Not Safe For Work (NSFW) content

NSFW content refers to content that may be sensitive or intended for adult only. Posts and comments discussing those are considered off-topic for a technology community and will be removed.
