The button combination works in most cases but WILL NOT while within certain apps or when playing games. Dont bother with the second screen shortcut as it is not available either. What I had to do was 1): Go to SETTINGS>DISPLAY>HOME TOUCH BUTTONS>BUTTON COMBINATION. Then drag the "CAPTURE" button (looks like a pen inside of the border box) up to add it to the normal 3 HOME TOUCH BUTTONS which will now give you 4 buttons available. Now you will be able to access this button quick by flicking once from screen edge EVEN IN LANDCAPE (ROTATED) MODE AND WHEN IN APP/GAME. 2): THEN, if you want the Home Screen Buttons always available when using a specific app/game, from SETTINGS>DISPLAY>HOME TOUCH BUTTONS>HIDE HOME TOUCH BUTTONS, select the specific apps that you want your home touch buttons always visible in while using and unhide them individually from the list shown. The the HOME TOUCH BUTTONS (INCLUDING YOUR NEWLY ADDED SCREEN CAPTURE BUTTON) will now always be shown WITHOUT NEED TO FLICK THE SCREEN FROM THE EDGE. Hope this eases your frustration!
