Capture screen is a function that is frequently used. When the SamSung Galaxy Tab 2 comes out, it has a screen capture button in the home screen.
However, after Android updated to Ice Cream Sandwich (4.0) and Jelly Bean (4.1), the screenshot button is removed from home.
Fortunately, we can still use the “Power + Volume Down” combination to do it. After holding down both bottom for 2-3 seconds, you can here a camera click and the screenshot it taken.
