For those of you who want to taste the latest Android 5.0 Lollipop, you don’t have to wait until Samsung updates their firmware, which could be months away.
Better, just grab the latest CM12 ROM beta, which is a full Android 5.0 Lollipop custom ROM that will give you every Lollipop feature including the vastly improved performance (near 20-30% improvement in Antutu benchmarks as shown in video, which matches Note 4 stock Antutu benchmarks!!!), battery life (along with battery saver feature which can save you in emergencies), and superfluid UI, which you can actually feel.
For root, CM12 ROM comes with root by default so you don’t have to worry about anything but just installing. UPDATE: To get full root, please flash latest SuperSU zip file (see below) otherwise you will not get full root.
Best of all, this CM12 “beta” version is nearly perfect as everything including camera, NFC, voice, 4G LTE, and bluetooth are working out of the box. In fact, this is the best Android 5.0 Lollipop ROM I have seen other than a real Nexus device (like Nexus 5, Nexus 10). It’s so good I am using my T-Mobile S5 as daily driver for this whole week and have encountered zero problems.
