Introduction:
Windows Phone application is not allowed to modify some of the device’s settings directly.As a developer we can't access the phone functionality directly.And so alternative way is "launch the settings screen " from the our app.However one of the most wanted functionality is added in "WindowsPhone 8 sdk" is "URI schemes"
This topic lists the URI schemes that can be used to launch built-in apps. Many of the apps built into Windows Phone can be launched from your app by calling LaunchUriAsync(Uri), passing in a URI that uses the scheme associated with the app you want to launch.
