For example you would think that certain settings could be toggled by voice, but unfortunately it was not available, at least until now. According to the folks at Android Police, it seems that Google has finally enabled the toggling of certain system settings using just your voice, such as enabling or disabling WiFi, the flashlight function, and Bluetooth.
Android Police notes that these three seem to be the only system commands recognized at the moment, and other commands such as putting the phone to Airplane mode, Location data, Brightness, Volume, NFC, and Data don’t work. Apart from NFC and Data, trying to use voice commands for the other features will instead send the user to the menu instead where they’d still have to toggle it by touching the display.
This appears to be exclusive to Android 5.0 Lollipop so if you’re using an older Android build, you’d be out of luck. Users with Lollipop will also want to make sure that their Google Search is updated to the latest version which should 4.1.29. We’re not sure if more commands will be added in the future, but this is a good and somewhat obvious start.
