Control Center: Turn on or off Airplane mode, Wi-Fi, Bluetooth, and Do Not Disturb. Lock your screen’s orientation or adjust its brightness. Play, pause, or skip a song. Connect to AirPlay-enabled devices. And quickly access your flashlight, timer, calculator, and camera.
New Notification Center: New notification center features give you a convenient summary of, well, today. One glance at your iPhone and you’ll know if it’s a certain someone’s birthday, if you’ll need an umbrella, or if traffic will slow down your commute. You’ll even get a heads-up on tomorrow. You can access Notification Center from any screen, including the Lock screen. Just swipe down.
New Multitasking: Press the Home button twice to see preview screens of the apps you have open. To quit an app, just swipe it up and out of preview.
