What is Networking & Wireless on my iPhone settings?
On my iPhone in System Services, Networking & Wireless is turned on. What does this do and should I leave it on?
iPhone 12 mini, iOS 16
Do you mean Settings > Privacy and Security > Location > System Services > Networking and Wireless?
If so, whether you leave it on is entirely up to you. All of the options in this menu are system services which use your location data. Some of it makes sense, like Emergency Calls and SOS. I'd leave that one on, haha. But for Networking and Wireless, when you try to turn it off, it says "Turning off location for networking and wireless may affect Bluetooth, Wi-Fi, and Ultra Wideband performance". I would recommend just trying it. If nothing breaks, you can decide for yourself whether to leave it on.
