"The Samsung-made Galaxy Nexus was launched way back in 2011, and officially got updates till Android 4.3 Jelly Bean before Google abandoned it. However, alternative Android OS developer Cyanogen kept the device alive thereafter, releasing a stable Android 4.4-based CyanogenMod 11 ROM for the device in 2013.
Now, the team has released the first Android 5.1-based CM 12.1 nightly build for the Galaxy Nexus, allowing users to enjoy the Android Lollipop experience on the device. The build weighs in at around 250 MB.
