The Settings app is one of the most important on your phone, as it's where you customize and control everything your device can do. But it's also one of the most intimidating apps, given its many menus and sub-menus; as such, many people never realize when those options change. Here's a look at what's new and different in Settings in iOS 7, organized in the order in which sections appear on the app's main screen.
Minor reorganization
As happens in every new version of iOS, the Settings app's main screen has undergone some minor renovations that don't really affect its functionality. The icons have adopted iOS 7's flat-but-colorful look, with new designs for all top-level settings, and Apple has slightly tweaked some names—for example, iOS 6's Brightness & Wallpaper item has given way to Wallpapers & Brightness in iOS 7.
Wi-Fi
One change here, though minor, is nevertheless useful: iOS 6 and earlier listed all available networks under the Choose A Network section, with a checkmark designating the connected network.
Your current network is helpfully listed separately from other available Wi-Fi networks.
