Android 7.1 hits the Galaxy Nexus and 2013 Moto X via CyanogenMod and Unlegacy ROMs
When a company says that they are going to stop supporting a phone, what they usually mean is they will no longer push firmware updates to the handset. When this happens, the only chance customers have to ever run the latest build of Android is if developers build a custom ROM for it. In the case of the Galaxy Nexus and the 2013 Moto X, Android 7.1 Nougat is now available thanks to the CyanogenMod and Unlegacy Android communities.
