Apple Is Testing a Beta Fix to the iOS 11 Control Center's Wi-Fi and Bluetooth Switches
Apple's developers are seemingly testing whether that element of the design needs a formal fix,
. In the latest beta version of
Hitting the wi-fi switch in the control center, for example, displays a message reading, "The current Wi-Fi network and others nearby will be disconnected until tomorrow. Wi-Fi will continue to be available for AirDrop, Personal Hotspot, and location accuracy." The Bluetooth equivalent reads, "Currently connected accessories will be disconnected and other accessories will not connect [until tomorrow]. Bluetooth will continue to be available for Apple Watch, Apple Pencil, Personal Hotspot, and Handoff."
There are a number of situations in which either function might turn themselves back on before the next day, such as changing location, reconnecting to devices or restarting the phone, MacRumors noted.
Note that the change is only a beta, so Apple could still decide the fix isn't a particularly good solution before pushing it out to users.
The decision to leave the wi-fi and Bluetooth chips on iOS devices activated when disabled in Control Center was intended for convenience-i.e., to allow users to simply hit the button and not have to waste time fiddling around in settings when they want to use them again-but it did attract some attention as a security risk. There wasn't any in-device explanation that the wi-fi chips or Bluetooth remained on, leaving the phones open to potential wireless attacks during a zero day vulnerability or enabled through malware. This change apparently does not resolve the security concern, which should be minor for most users, but at least it does explain what's happening behind the scenes more clearly so said users can make their own decisions on how to use Control Center.
