I love Samsung Galaxy Note.
It is not just a smartphone but a tablet too, permitting the user to enjoy clear visuals on the move on relatively a large screen.
The most notable feature of galaxy note is its heart rate monitor placed at its back. It comes with a S-pen that further has two options of a fountain and a highlighter.
You can check more details at Samsung India site.
