How to enable the DayDream feature in the Nexus10? I know that in Android JellyBean 4.2 there's a new feature called DayDream. I want to access it in my Nexus10 but don't know how. 

How can I enable and use it?
Go to Settings -&gt; Display -&gt; Daydream and select your desired daydream. After this, tap When to daydream and select when you want it to work.

Now, when you charge/dock the device, leave the screen on and after a while, the daydream will start. For me, this required me not to lock the screen manually by pressing the power button, and disabling Stay awake from Developer options.
