CyanogenMod has started to roll out CM 12 a.k.a Lollipop to a lot of devices, including the Galaxy S5, HTC M8, Nexus 6 and so on. Daily, more and more devices are able to enjoy Cyanogen’s take on the stock android build of Lollipop. Though many are still anxiously waiting for it to reach their devices. If people like me are still waiting and can’t wait any longer, there are plenty of unofficial CM12 builds all over the net. One in particular is made for a 4 year old device, the Samsung Galaxy S2.

Those of you who still have this bad boy, can now breathe new life into the phone. Thanks to an XDA User Lysergic Acid, who posted the pure, yet unofficial CM 12 build of Lollipop 5.0.2. After using it for a week, the build seems to be quite stable for daily use, even though it is still under beta stage. Running the Galaxy S2 (GT-I9100) on Lollipop is a great experience. All the animations that come with the ROM are really appealing and just fun to use. The ROM is not very heavy on the battery as well, so that is a plus point always. No crashes in any apps so far as well. One thing the developer himself has mentioned that the camera app still has issues recording High Definition (HD) videos.  So, just change the settings to 480p and your good to go. I’m sure this will be corrected in future builds.
