LineageOS is a free, community built, aftermarket firmware distribution of Android 10, which is designed to increase performance and reliability over stock Android for your device.

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 repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.

What's not working:
  • Bootloop on first install (must force reboot after clean install)
  • LiveDisplay/NightLight
  • IMS (no volte)
  • Need more testing (encrypted /data not supported)


  • Make sure TWRP with SAR support has been installed and functional.
  • Download the latest build (and optionally gapps).
  • Reboot to recovery
  • Wipe system, data, and cache (required if you switch from other ROMs)
  • Flash the latest build, gapps, and magisk.
  • Reboot

Reporting Bugs:

DO NOT Report bugs if you're running a custom kernel or you installed Xposed
Grab a logcat right after the problem has occurred.
If it is a random reboot, grab /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless).

Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues. For now please report any bug below.

Ok thanks. I'll try to check into that. Providing a log would have been helpful as I do not have a dual sim model to test with.
