Control Center is a useful new feature on iOS 7 that brings quick toggles to the iPhone, iPod touch and soon iPad, accessible by swiping up from the lock screen or home screen, but perhaps you don’t want to have the arrow icon showing on the bottom of your lock screen. Not to worry.
To enable or disable Control Center on the lock screen in iOS 7, simply navigate to Settings > Control Center > Access on Lock Screen and switch the toggle off. It’s that easy. This method applies to all devices that support iOS 7: iPhone 4, iPhone 4S, iPhone 5, iPod touch 5G and soon the iPad and iPad mini.
