One of iOS 11's key new features is a redesigned Control Center that is highly customizable thanks to 3D Touch integration.
When you deep press on the system toggles pane, for example, a larger pane pops open with previously hidden AirDrop and Personal Hotspot controls.
On iOS 11, users can add, remove, and organize controls in Control Center through the Settings app. Simply follow these steps.
Control Center remains accessible by swiping up from the bottom of the screen nearly anywhere on iPhone 8 and iPhone 8 Plus or earlier.
On the iPhone X, Control Center can be opened by swiping down from the top right part of the screen next to the TrueDepth front camera system.
