Cards appear at the bottom of the Home Screen to keep you informed about a variety of information. If not all of the contents of a mail message, SMS message, or other message does not fit within a card, you can tap the card and then swipe to scroll the displayed text. With some cards, swiping from right to left will display detailed information or operation buttons.
