11. Redesigned Control Center
Control Center in iOS 11 has received a major redesign. All of the tiles are available on a single page and you can 3D Touch a tile to expand it for more options. If you 3D Touch on the connections tile, you can view additional toggles such as Cellular Data and Personal Hotspot. Additionally, Control Center is now customizable. Go to Settings > Control Center and from there, you can add or remove controls.
