UNLOCK THE HIDDEN JELLY BEAN “BEANFLINGER”
By default, you can choose one of the five stock Daydreams – Clock, Colors, Currents, Photo Frame and Photo Table. There is actually a sixth Daydream called BeanFlinger.
To unlock this Daydream, you have to go to Settings > About Phone > Android version. Tap a few times on the Android version number and a large Jelly Bean smiley face will appear. Tap and hold on the face for a few seconds and you will unlock a screen with jelly beans floating around.
