One of the key differences between the Galaxy Note 4 and other big screen smartphones is that it comes with a bundled S Pen stylus. The S Pen isn't for everyone but it's a feature that we've grown to love over the past few months.
On the most basic level, the S Pen allows you to write and draw on the screen. There are, however, a number of other uses for it which range from the powerful S Note note-taking application to setting quick and easy shortcuts to key features like Image Clip and Screen Write.
We don't use the S Pen all the time but it's an extremely nice option to have, especially if you rely on your smartphone to get work done. It's a powerful tool and one of the reasons why we continue to enjoy the Galaxy Note series.
