After accepting the new Apple upgrade to iOS 7.1 on my iPhone 4S, I cannot remove the half month calendar view to show only the daily view. Help!
Before you panic, try resetting your iPhone by simultaneously pressing and holding the Home and Sleep/Wake buttons until you see the Apple Logo. This can take up to 15 seconds so be patient and don't release the buttons until the logo appears.
Try again to see if the problem persists.
