Teaching you how to activate the Gingerbread system zombie robot Easter egg

As early as last December, when Google released the Android 2.3 Gingerbread system, some electronic archaeologists (specialists in uncovering unknown content in new systems) discovered a unique Halloween wallpaper in the SDK, which featured a green robot and a zombified gingerbread logo. However, almost no one knew its actual purpose.

This zombie robot wallpaper is actually a hidden Easter egg that Google placed inside the new system, but how to activate it remains a mystery. We know it's there, but we don't know why it's there.

Now, someone has finally discovered the way to unlock this Easter egg. Whether you have a Nexus One or a Nexus S, as long as you have the Android 2.3 system installed, go to the settings menu and tap on the system version, specifically the Android 2.3.1 line, and do it quickly. You'll then find that the zombie wallpaper has appeared.
