On all Samsung tablets, pressing and holding the Power and Volume Down buttons at the same time will prompt your tablet to take a screenshot after a second. On Samsung tablets which have physical Home buttons, you can also hold down Power and Home to take a screenshot. You'll find the Power button at the top of the right side of the tablet's housing, and the Volume Down button will be the bottom button in the "Volume" group of buttons on the right side of your tablet. If you have a tablet that has a physical Home button, it will be at the bottom of the screen. Open the app, screen, or page on which you want to take a screenshot. Press and hold the Power and Volume Down buttons, and don't release them until prompted. This indicates that a screenshot has been taken. You should also see the screenshot's preview appear in the bottom-right corner of the screen, and a photo icon will appear in the notification bar in the top-left corner of the screen. Once you've taken your screenshot, you can open it in one of the following ways:   Notifications menu — Swipe down from the top of the screen, then tap the Screenshot captured notification.  Gallery — Open the Gallery photos app, tap the ALBUMS tab, tap the Screenshots album, and tap your screenshot.
