This is called android Esther egg.

Each version of Android from Gingerbread (Android 2.3) has included an Easter egg, which is always accessed in the same way.

Android’s Easter eggs pay tribute to nyan cat, Tron, zombies, and jelly beans & many more others. Each Easter egg is themed to fit with the Android version’s release name.
ANDROID EASTER EGGS:
Android 2.3 (Gingerbread) - A zombie painting
Android 3.0 (Honeycomb) - A honeybee with a word "REZZZZZZZ..." inspired by Tron: Legacy movie
Android 4.0 (Ice Cream
Sandwich) - Nyandroid
character inspired by Nyan Cat
Android 4.1 - 4.3 (Jelly Bean) - Red Jelly Bean
game
Android 4.4 (KitKat) - A spinning K, then Android logo, then Windows Phone style page with small tiles.
Android 5.0 (Lollipop) - Flappy bird game, lollipop style.
Android 6.0 (Marshmallow) - New Flappy bird game, Marshmallow style.

Now this is the way you can access them all
Go to settings>About and tap on the Android version number repeatedly , the hidden android logo for your phone version will appear.
If you hold down on the image another image will appear and hold down again and the final image will appear.

I'm using Kit Kat version. See the pics of mine below. You can do it the same way and see yours. It's cool

The last pic that will appear is an Endless game you will keep playing until your battery dies.
Indicate if it works for you
