New Control Center Shortcuts for Wi-Fi and Bluetooth
Apple is continually putting more functionality into the Control Panel. After relocating the Control Panel to the top of the screen, Apple then added customization options in iOS 11. Now in iOS 13, you can now choose your Wi-Fi and Bluetooth options straight from the Control Panel without going through the Settings app.
Tap and hold on the Wi-Fi/Bluetooth icon to open up additional options, then tap and hold the Wi-Fi icon to see all available Wi-Fi networks, or do the same for the Bluetooth icon to see all Bluetooth devices.
