If you don't want to create shortcut icons on your homepages for your settings. You can still use Siri to access the short cuts.
To do this create a contact in the contacts app with first name per the Preference short cut below.
Then for the Website URL for that contact put in the code next to the Shortcut name below. That is it - nothing more.
So for example for Airplane Mode - you would create a contact with "Airplane Mode" for the first name. Then for the Website URL you would enter "refs:root=AIRPLANE_MODE" With the case as shown. Case does matter. That is all you would enter for that contact - First Name and Website Info. Then Tap "Done"
Previously if you asked Siri to Turn Airplane Mode On - she would have replied "I'm Sorry, I'm Afraid I can't do that"
Now simply ask Siri to "Show Airplane Mode Contact". Siri will now say "Ok here is the contact" and then just tap on "prefs:root=AIRPLA..." and in this case it will take you to the settings screen and turn airplane mode on.
The one downside of Siri shortcuts - is that they do not work when in airplane mode - so you will not be able to use any of the others when in Airplane mode. But still this is a quick shortcut to get to the settings - rather than having to try to find where on your iOS device you hid those shortcut icons or the settings app.
