Canonical announced Ubuntu OS for smartphones last week, and here we have a video demo of the Ubuntu OS running on the Galaxy Nexus. The Ubuntu OS for phones has an intuitive gesture-based User Interface, right from the lock screen. The colors in the phone OS are similar the Ubuntu for desktops. It also has a sidebar to access apps quickly.
