There is a new feature in the gigantic iPhone 6 and iPhone 6 Plus. Because sometimes it’s hard to reach and touch the upper part of the screen when you are holding the iPhone in one hand you can double tap (actually double touch) the home button and the screen will shift half way down so you can reach the upper content, tap it and then the screen shift back up to it’s normal position.
