The Samsung Galaxy S3 wont be getting the Android 6.0 Marshmallow update officially from Samsung of course, since the device didn’t even received the Lollipop release from last year. But that doesn’t mean it’ll be left out of the Marshmallow sweetness. Galaxy S3 will get CM13 with Marshmallow.

Galaxy S3 CM13 update will be available as soon as CyanogenMod 13 source code is released. S3 enjoys good support from the custom development community, so we’re pretty sure that holy folks over at xda will be quick to build CM13 for Galaxy S3 as soon as it’s available.

As for CM13 release date, well we don’t have an exact date yet since CyanogenMod hasn’t given any official statement yet about it, but it’ll be quicker. Say mid-october 2015.

Initial Galaxy S3 CM13 builds may not be suitable enough to be your daily driver, which is normal, happens with every major Android update and their AOSP based ROMs like CM. And with a little more time, a month at max, most of the bugs will be sorted out and you’ll be running Marshmallow update on your S3 without a flaw.

Seriously, the whole world of custom ROMs like CM, starts to make so much more sense when you’re in possession of an outdated device and hoping to get the latest Android update on your device.

Galaxy S3 will be quick to get CM13 because of its popularity, so if you receive the love of custom development community, make sure you purchase a device that’s popular. Because in the long-run, only custom ROMs like CM makes sense out of your device.

Anyway, Galaxy S3 CM13 update with Android 6.0 Marshmallow will breathe new life into the 3 year old device. Cheers!
