LineageOS, also known as LineageOS Android Distribution and Lineage (/ˈlɪn.i.ɪdʒ/), is a free and open-source operating system for smartphones and tablet computers, based on the Android mobile platform. It is the successor to the highly popular custom ROM CyanogenMod, from which it was forked in December 2016 when Cyanogen Inc. announced it was discontinuing development and shut down the infrastructure behind the project.[3][4] Since Cyanogen Inc. retained the rights to the Cyanogen name, the project rebranded its fork as LineageOS.[5]

LineageOS was officially launched on December 24, 2016, with the source code available on GitHub.[6] Since that time LineageOS development builds now cover more than 178 phone models[7] with over 1.6 million installs,[8] having doubled its user base in the month February–March 2017.[9]



CyanogenMod (often abbreviated "CM") was a highly popular[10] open-source operating system for smartphones and tablet computers, based on the Android mobile platform. Although only a subset of total CyanogenMod users elected to report their use of the firmware,[11] as of 23 March 2015, some reports indicated over 50 million people running CyanogenMod on their phones.[10][12] It was also frequently used as a starting point by developers of other ROMs.[citation needed]

In 2013, the founder, Steve Kondik, obtained venture funding under the name Cyanogen Inc. to allow commercialization of the project.[13][14] In his view, the company did not capitalize on the project's success, and in 2016 he either left, or was forced out[15][16] as part of a corporate restructure which involved a change of CEO, closure of offices and projects, and cessation of services.[17] The code itself, being both open source and popular, was quickly forked under the new name LineageOS and community efforts began to resume development as a community project.

CyanogenMod offered a number of features and options not available in the official firmware distributed by most mobile device vendors. Features supported by CyanogenMod included native theme support,[18] FLAC audio codec support, a large Access Point Name list, Privacy Guard (per-application permission management application), support for tethering over common interfaces, CPU overclocking and other performance enhancements, root access, soft buttons and other "tablet tweaks", toggles in the notification pull-down (such as Wi-Fi, Bluetooth and GPS), and other interface enhancements. Many of the features from CyanogenMod would later be integrated into the official Android code base. CyanogenMod did not contain spyware or bloatware, according to its developers.[19][20] CyanogenMod was also said to increase performance and reliability compared with official firmware releases.[21]


Similar to CyanogenMod, the project is developed by numerous device-specific maintainers and uses Gerrit for its code review process. It also retained the old versioning format (for example, Android 7.1 is LineageOS 14.1). Builds are released on a weekly basis and are signed with LineageOS' private keys.[22]

Prior to the official launch of LineageOS, many developers from XDA had already developed unofficial versions of LineageOS from the source code.

Supported devicesEdit

As of 8 September 2017, LineageOS officially supports 190 devices,[24] including Nexus and Google-released devices. Official builds on the current development branch are labeled as "nightly," although they are generally released once per week with builds for various devices staggered throughout the week to ease the load on the automated build infrastructure. For the first two months of the project, they also produced parallel experimental builds to allow in-place upgrades from previous CyanogenMod installations and ease migration to LineageOS.[25][26][27][28]
