If there’s a screen on a Samsung Galaxy S4 that you need to save or share, it’s very easy to capture it.
Open the screen you’d like to capture.
Press and hold the standby key on the right side and the home button at the same time. Wait for the border around the screen to flash white.
The image will then be saved to your device. You can quickly access it by swiping down from the top of the screen and tapping the image in the notification tray. You can also delete, edit, or share the screenshots thanks to helpful shortcuts there.
