On the Galaxy S9, S9+, and Note8, there are several ways to take screenshots. One is using a swipe of your palm. Activate it by going to Settings, and turning on 'Palm swipe to capture' in Advanced features. Swipe the edge of your hand horizontally from right to left or left to right, and from edge to edge. Make sure your hand stays in contact with the screen. Or take a screenshot the more traditional way—by pressing two buttons, the power key and volume-down key, at the same time.
Once the screenshot is captured, you will get a preview and several options to do more at the bottom of the screen, such as drawing on the image, cropping the image, or sharing from the menu. Another option given in the menu is Scroll capture, the feature that lets you take scrolling screenshots of long articles or images. To use Scroll capture though you first need to enable Smart capture from Advanced settings. Then you can simply tap “Scroll capture” from the options that appear at the bottom of the screen after capturing the screenshot. Keep tapping the Scroll capture button to continue capturing long content. The Galaxy Note8 offers another way to access Scroll capture. Take out your S Pen to activate Air Command, choose Screen write then Scroll capture. Capture long text or images by scrolling and then annotate with the S Pen.
To select certain shapes, there's Smart select. On Galaxy S9, S9+, S8, and S8+, enable the feature by going to Settings > Display > Edge screen > Edge panels. You're now able to select from Rectangle or Oval for screenshots in those shapes. Animation lets you select a part of a video to create an animated GIF. On the Galaxy Note8, take out the S Pen to activate Air Command, and tap Smart select from the menu. Use your S Pen to select any shape you want, or to select a video section to get animated GIFs.
