LineageOS is a free, community built, aftermarket firmware distribution of Android 12, 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.
- Follow the instructions on the wiki page for your device https://wiki.lineageos.org/devices/#samsung
Note: You may use Odin instead of Heimdall, for this you will need to rename the recovery image to recovery.img and pack it into a tar archive.
- Builds: https://download.lineageos.org
- GApps: https://wiki.lineageos.org/gapps.html
- DO NOT Report bugs if you're running a custom kernel or you installed Xposed
- Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
- 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)
- If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log
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. Any bug not reported in the bug report format below may be ignored.
