It used to be so simple: If you swiped open the iOS Control Center and tapped the Bluetooth icon, then Bluetooth would be toggled on or off. That was it, and the same went for Wi-Fi.
In iOS 11, tapping the same Bluetooth button doesn’t do that. Instead, the Control Center Bluetooth button disconnects your iPhone or iPad from connected Bluetooth accessories, leaving the actual Bluetooth radio on. What’s more, not all accessories get disconnected. Just what in the blazes is going on here?
