This time, however, the Android 4.2.1 Jelly Bean firmware has arrived for the international variant of Galaxy Note 2 N7100 thanks to CyanogenMod 10.1 aka CM10.1. CyanogenMod has always been known for its highly customizable interface that’s not present in stock ROM.
Few of the notable Android 4.2.1 Jelly Bean features available here are multi-user support, gesture typing, new quick settings option, lock-screen widget, new camera app, photo sphere, improved Google Now, new daydream feature, and miracast display, to name a few.
