The Samsung S Pen is a stylus designed for use with select Samsung Galaxy devices, particularly the Galaxy Note series and some Galaxy Tab tablets. It allows users to write, draw, and navigate their devices with precision. The S Pen features pressure sensitivity, enabling a more natural writing experience, similar to pen on paper. In addition to basic writing and drawing functions, the S Pen includes various features such as Air Actions, which allow users to control their device remotely with gestures. It also supports screen-off memo, enabling quick note-taking without unlocking the device, enhancing productivity and creativity.
