Cyanogen on Nexus 7 (2012)

CyanogenMod is an aftermarket firmware for a number of cell phones based on the open-source Android operating system. It offers features not found in the official Android based firmwares of vendors.

Cyanogen commercially develops operating systems pre-installed on some devices (OnePlus One, YU Yureka, YU Yuphoria, Andromax Q, Lenovo ZUK Z1, Wileyfox Swift, Wileyfox Storm) based upon the CyanogenMod source code.
Initially distinguished with the suffix -S (CyanogenMod 11S), with version 12 Cyanogen rebranded the custom offering as Cyanogen OS.
