CyanogenMod 13 is the latest version of the popular open source custom ROM. It delivers Android Marshmallow to hundreds of devices, many with no hope of ever receiving an official update.

Another phone is getting its first taste of CyanogenMod, but the version number is 12.1. This is the Galaxy SIII Neo. The nightly build does not have NFC, and the maintainer says it never will due to a lack of necessary source code. Bummer. Nonetheless, I hardly ever use NFC, and many of you probably get by without it too.
