Nexus 5 series' software update service was disbanded recently as it crossed the two-year age limit, leaving the device stuck with Android Marshmallow OS.

However, Nexus fans, who are still hanging on to the former flagship phone, need not feel disheartened. There are numerous custom ROMs in the internet. Among them, NitrogenOS is popular. It promises not only the new v7.0 Nougat features, but also bring performance tweaks, extend battery life and several other value-added options to enhance user-experience.
