I was just playing with my Nexus 7 when I realized that the Settings panel no longer had developer options. I did a quick Google search which reveled that the developer options is actually hidden in android 4.2 Jelly Bean and you needed to enable it first. In order to enable the developer option you need to go to the About tablet/About phone and tap the Build number three times.

This gives you a Toast notifying "You are now 4 steps away from becoming a developer". Now keep on tapping the Build number four times and you will get a Toast notifying "Now you are a developer". If you keep on tapping the Build number you will get a Toast notifying you "No need, you are already a developer".

This got me curious and I searched for more Easter Eggs on the new 4.2 Jelly Bean. I found one more on the xda-developers forum by mrsifter. This lets you have "BeanFlinger" option in you Daydream menu. In order to activate this , you need to repeatedly tap the Android version in the About tablet/ About Phone menu which will give you a Jelly Bean wallpaper. Now long press the Jelly Bean wallpaper and you will get the "BeanFlinger" live wallpaper and also the option will be added to your Daydream menu. Now you can select the "BeanFlinger" by going to Settings>Display>Daydream.

If you guys do know any other Easter eggs for android 4.2 Jelly Bean please do let us know.
