Samsung stopped supporting the Galaxy Note 2 long time back but XDA is still pumping out ROMs and updates for this android phone. XenonHD ROM is now available for the device that brings you latest Android 7 Nougat on it. This obviously requires you to have Galaxy Note 2 custom recovery or TWRP onboard as that is the only way to install a third party, unofficial ROM on an android phone.
This Android 7 firmware is based on cyanogen mod 14.1 which means you get vanilla android experience – something that you find on Nexus range of phones. Please note that gapps are not preinstalled on it, but you can install them immediately after ROM installation in custom recovery. Download package from opengapps.org and install latest package from there.
Here are the features of the ROM:
