10. Find The Android Easter Egg

Fun fact: If you have an Android phone, you'll be able to unearth a fun Easter egg that will change depending on which version of the operating system you're running. You have to get a little fancy to do it — here's a set of instructions for you — but once you work through the steps, you can start having some fun. Earlier versions of the Android Easter egg simply consisted of a piece of art, like a zombie painting in Gingerbread; later versions, however, have gotten more elaborate: Jelly Bean had the "Red Jelly Bean Game," and Lollipop and Android have had a game similar to Flappy Bird.
