Use the S Pen to write and draw, or use it as a remote control to control your device. The S Pen also turns your gestures into actions, allowing you to, for example, control a presentation or a video and take a picture with a click without holding the smartphone in your hand. The screen of your Galaxy smartphone or tablet registers how hard the tip of the S Pen presses on the screen surface. This allows you to vary the thickness and opacity when writing notes, for example. The side button of the S Pen can be customized and has functions such as taking screenshots, taking a photo, opening a specific app, etc.
