CM12.1 ROM for Galaxy S3! [Android 5.1.1][Official]


For those of you who have been waiting for official CM12.1 with latest Android 5.1.1, we have some good news for you as official CM12.1 ROMs are finally here!

These are based on latest CyanogenMod sources with latest Android 5.1.1, meaning you will get all of the new Android 5.1.1 features including soft buttons with hardware keys disabled.

Best of all, these builds have everything working out of the box including camera and Netflix. I know many of you with Sprint S3 were having trouble but these CM12.1 have flawless camera for all S3 models. (official builds are available for all S3 models except GT-i9300)  Performance is excellent along with great battery life on these builds.

Best part about CM12.1?  You do not need to do any wipe if coming from CM12 or updating from another CM12.1, just dirty flash and you will be updated but do make a backup ROM just in case!

The features on CM12.1 ROM are nearly identical to the Note 4 so we won’t go over it again but definitely try out these new builds as they are official and run great out of the box.  (You can check out latest video of CM12.1 ROM review here for all the new features though.)
