Siri is the personal voice assistant pre-installed on your iOS device. Introduced in iOS 5, the voice assistant allows a wide variety of functions, conversions, information queries, and fun comments to be invoked with just your voice.

But did you know Siri can also be used to toggle certain system settings on or off too? In this tutorial, we’ll show you how.It’s no longer necessary to open the Settings app to turn some (not all) features on or off – Apple has made it to where you can actually use Siri in some cases.

Using Siri to turn system settings on and off,it’s as simple as saying “Turn Wi-Fi Off” or “Turn Bluetooth Off” when you have launched Siri and she awaits your command.

• Airplane Mode

• Brightness
  

• Wi-Fi 

• Bluetooth

• Do Not Disturb

• Cellular Data

• Low Power Mode

• Invert Colors

• Night Shift

• VoiceOver

  
  

When you ask Siti to do these things, she’ll reply with “OK, I turned off…” whatever you may have asked for her to turn off. The same would occur if you wanted her to turn something back on by saying something like, “Turn Bluetooth On.”

Indeed the array of settings that Siri can actually toggle on or off are very limited, but Apple is constantly adding new features to Siri and giving her more abilities with each major iOS released on an annual basis. Nevertheless, Siri is a great way to toggle the available functions on or off if you ever needed to without using your hands.
