go into Samsung Kies to see if the update is available there. Or, go to settings from the "About Tablet" page on your device. Based on the comments left by those who have updated their tablet, the update can be found on Kies (make sure your battery is fully charged!) and it removes both the screenshot icon and Swype. Don't fret about losing Swype as the swipe to type feature will eventually return on Android 4.2 with Google's own "Gesture Typing," which includes predictive input and a cool blue tracer.
