LineageOS
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.
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.
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. In March 2017, it reportedly had one million users with the OnePlus One being the most popular device. Recent development updates were posted on their blog, though this became infrequent after 2019.
During August 2017, the LineageOS team held a Summer Survey in which they asked users for feedback to improve the development of the operating system. The results were published in October and, according to the team, they used the gathered data to improve the upcoming LineageOS 15 release.
As a response to one of the main suggestions received during their first public survey, LineageOS launched a section on their blog titled "LineageOS Engineering Blog" where Lineage maintainers and developers can contribute articles discussing advanced technical information pertaining to Android development.
During the first week of April 2018, LineageOS released new builds with the "LOSGenuine" April Fool's prank that informed unaware users of the software possibly being counterfeit via a persistent notification (which could not be disabled unless the user ran the following command in a root shell):
