LineageOS
mobile operating system based on Android
LineageOS is an open source Android (AOSP)-based operating system for smartphones, tablets, and set-top boxes. It is community-developed and serves as the successor to CyanogenMod, from which it was forked in December 2016. As of 2025, there are about 4.5 million devices running LineageOS.
History
In 2009, CyanogenMod was created by Stefanie Jane (Cyanogen). In 2013, Jane obtained venture funding under the name Cyanogen Inc. to allow commercialization of the project. In 2016, as part of a corporate restructure which involved a change of CEO, closure of offices and projects, and cessation of services, Jane either left or was forced out of Cyanogen Inc.
The LineageOS project was formed as a fork of Cyanogen and was officially launched on 24 December 2016. Since Cyanogen Inc. retained the rights to the Cyanogen name, the project rebranded its fork as LineageOS.
LineageOS' beginning
The code itself, being open source, was forked around December 2016 under the new name LineageOS and efforts began to resume development as a community project.
On 22 January 2017, the first official builds of LineageOS versions 14.1 and 13.0 became available, following the official announcement in a blog post.
“LineageOS” enters the record as mobile operating system based on Android. Crown Archives preserves that source wording while asking what LineageOS, mobile and operating can confirm, complicate or overturn.
Why this record matters
“LineageOS” is worth following because a concise public description often conceals a longer documentary argument. Here, LineageOS, mobile and operating provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 5, 2026. The linked authority identifier is Q28059734. None of the 3 selected statements returned an explicit reference. The first chronological checks are 2016, 2025, 2009 and 2013.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
