End calls

[Xcat]

Hello everyone.
I just got myself a Lumia 520.
I've read it has the option to end incoming calls by just turning the phone upside down without pressing buttons at all.
Unfortunately, my Lumia refuses to do so.
Any ideas why? Should I enable this option somehow?
Thank you in advance.

I don't know about any option like that, but their is one option available to turn an incoming call silent by just flipping it !!

The feature you are looking for is 'flip to silence'. You will find it under audio in your settings. What it allows you to do is to silence incoming calls by flipping your phone face down. It doesn't end a current call.
