UI scalling in android with Unity 4.6 beta

Hi,

I just started using the new UI system and I have problem in scaling it up to fit my Nexus 4.

I place the UI elements perfectly on the unity editor (Like in the image):

But when I build it and run on my Nexus 4 it looks like it didn’t scaled to fit the screen :

I had the same problem with GUITexture before the new UI system, could anyone explain how to fix this and show me what I do wrong?

P.S. sorry for bad English ^^ and thanks for helping

Add a Reference Resolution component to your canvas, it deals with automatic scaling.
