How to switch on flip-to-silence in Nokia Lumia Amber update

One of the new features for Nokia Lumia phones with the Amber firmware update is "flip-to-silence", which lets you turn over your ringing phone to silence the ringer.

But as with many of the new features in Amber, it's hidden away in settings.

To activate or deactivate flip-to-silence go to: Settings > Audio and slide the screen to Enhancements where you'll find the on/off switch.
