Afterwards, they can view, edit, and share the screenshot in Gallery or a similar app.
Push the Power button and Volume down button at the same time for a couple of seconds.
Go to “Settings” -> “Advanced features” -> “Gestures”, enable 3 fingers screenshot, then swipe down with 3 fingers.
Swipe down to access the quick settings from any screen, and then click the “Screenshot” icon to take a screenshot.
You should see an animation showing you the screenshot. Please view the screenshot by tapping on the thumbnail in the notification tray or by visiting your Gallery application.
