LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github RepoAnd if you would like to contribute to LineageOS, please visit out Gerrit Code Review

Known Issues

Screenshots and Recents App thumbnails are blank

Runtime storage permission does not fully work (setns kernel patches are not applied, see com.android.cts.appsecurity.PermissionsHostTest#te stInteractiveGrant CTS test. After granting permission, the app will need to be restarted before it sees the new permission.)

Additionally, Dual SIM has the following limitations (once they work):

Both SIMs are always enabled (no way to disable one SIM)

"Receive incoming call while data is enabled" is always enabled

Installation

Make a backup!

If you were on CM 10.1 or a stock ROM prior to 4.2, upgrade to stock 4.2 first.

Install ClockworkMod recovery with SELinux support. Older CWM will result in a "status 7" error.

Reboot into recovery

If you are using a recovery which mounts /system on boot, unmount it before installing

Wipe data if coming from stock or other ROMs (You may get a "status 7" error if you fail to wipe.)

Install the ROM

Optionally install the Google Apps Addon (In Marshmallow, you MUST flash gapps before booting into the system for the first time or else the proper permissions will not be granted resulting in Setup Wizard crash. If you experience the crash, you will need to do a factory reset.)

To upgrade to a newer build, simply flash the zip. There's no need for data wipe or flashing Google Apps again. (However, if you are experiencing strange issues, you may want to try a wipe.)
