Recttransform and Screen Resolution problem

Hello There!

I have had the same problem as esitoinatteso in this thread: http://answers.unity3d.com/questions/976184/ui-recttransform-position-screen-resolution.html,

Where the UI elements appear correctly on the editor, but not on the mobile device. I have tried dividing by the screenScale, as well as multiplying, both doesnt work.

Heres the snippet of my code:

 ResumeButton.GetComponent<RectTransform>().position = new Vector3(Screen.width / 2 / screenScale().x, 6 * Screen.height / 10 / screenScale().y, transform.position.z);
 
 
 QuitButton.GetComponent<RectTransform>().position = new Vector3(Screen.width / 2 / screenScale().x, 4 * Screen.height / 10 / screenScale().y, transform.position.z);

Has anyone encountered something like this and could help me out? Its driving me insane...

Thanks a lot! :D
