really? what phone are you on?

  Galaxy S2, I know it worked on the original Galaxy S aswell. And I think I've seen it working on the Nexus S. It could be that Samsung added it to their phones and that it's not a Android feature itself.

    it is a samsung-specific feature. it is not present in AOSP or most other manufacturer builds of android.
