[EN] You can get the daily build of LineageOS for Samsung i9305 (Galaxy S3 4G) on this page : http://buildyourownandroid.selfhost.eu/smartphone/daily-builds/
This website is'nt run by me, so it can go away at anytime


If the website does go away, you can download the latest saved version on this page : /roms-i9305/dailybuild/
[Note]: Neither "Build-your-own-android" or myself are testing the Lineage daily builds, so i don't even know if they will boot and work properly, but you can still try. - Good Luck :)
