The Samsung Galaxy Nexus was one of the first critically acclaimed Android devices, as it used to run stock Android instead of the TouchWiz UI that was shipped as default UI for all Samsung devices.
The last CM builds released for the Galaxy Nexus phones were the CyanogenMod 11 Nightlies. Now, almost two years since the launch of Android 5.1, the CM team has built and released the first CM 12.1 Android 5.1 Nightly ROM for all Galaxy Nexus users to enjoy.
Since the first Nightly has only been made available for download you should install it with caution, as it contains some bugs and some apps aren’t working at this moment. If you own a Galaxy Nexus device, but you use it as a secondary phone, then you should really test the CM 12.1 Nightly ROM. Download the file from here and install it using the Custom Recovery Mode.
Google has stopped sending new updates to Galaxy Nexus phones since the Android 4.3 Jelly Bean release, despite the fact that the device was perfectly capable of handling the Android 5.0 Lollipop requirements. If you have stayed loyal to your Nexus phone and you are a fan of CyanogenMod, then you shouldn’t waste any time and install the new CM 12.1 Nightly ROM on your phone.
There is no word on the future availability of a stable CM 12.1 SNAPSHOT release, but we should learn more about this after a couple more Nightly builds are launched. Make sure to create a NANDROID ROM Backup for the already installed ROM before starting the CM 12.1 installation, so that you will be able to roll back your device to a working state in case something goes wrong.
If you own a Galaxy Nexus phone and you’ve installed the CM 12.1 Nightly on it, then you should let us know below. Also, feel free to list some of the best things that you’ve found in CM 12.1 after testing the firmware for a couple of hours.
