Samsung's Galaxy Note 3 was last upgraded to Android Lollipop in 2015, but sadly that's the last official update it will ever get because the device is more than two years old and no more eligible for any software update service.

However, those who are still hanging on to the former flagship phablet can still be able to enjoy Android Marshmallow features on Galaxy Note 3 by installing the custom ROM developed by Dirty Unicorn community.
