Each Version of Android since Gingerbread(Android 2.3) has included an Easter egg and every one of them can be accessed in the very same way.
Accessing Android’s Easter Eggs
To access the Easter egg in your version of Android, open the Settings screen and tap About phone or About tablet at the bottom of the screen.
Locate Android’s version number on the about screen and quickly tap it several times. The Easter egg will appear. If you’re using Gingerbread, look for “Firmware Version” instead of “Android Version”.
Jelly Bean (Android 4.1)
Jelly Bean’s Easter egg is a large, red jelly bean. Tap it with your finger and a face will appear.
Keep on Pressing the Jelly Bean and you’ll see an interactive Jelly Bean Mini Game will appear. You can move them around and swipe them across the screen.
Ice Cream Sandwich (Android 4.0)
Ice Cream Sandwich’s Easter egg is a pixel-art Android wearing an ice cream sandwich.
Keep on Pressing the Android and a swarm of androids wearing ice cream sandwiches will start flying across the screen.
Honeycomb (Android 3)
Honeycomb’s Easter egg includes art inspired by its code name – a honeybee, in this case. The honeybee is electric blue, in the style of Honeycomb’s other interface elements.
It has been noticed that Android 3’s theme seemed inspired by Tron: Legacy, so it’s no surprise that Honeycomb’s Easter egg includes a Tron reference.
The honeybee produces a word bubble with the text “REZZZZZZZ…”. “Rezzing” is a term used in the Tron Universe. In Simple Terms, it means Something that has been created in the Tron System.
Gingerbread (Android 2.3)
Gingerbread’s Easter egg is a zombie-themed painting called “Zombie Art” features a zombie gingerbread man, an oblivious Android and several zombies holding what appear to be mobile phones(Android?).
