Problem with modifying scrollPosition on android

I made a simple credits scene showing a scroll view with labels in it where in the update function the scrollPosition variable is modified so it scrolls down.
This works on PC, but on my android device nothing happens.

The update function where the scollPosition.y is modified

void Update()
		scrollPosition.y += Time.deltaTime*scrollSpeed;

And the OnGUI

void OnGUI() 
		GUI.BeginGroup(new Rect(0,0,Screen.width,Screen.height));  //note the 250 width and 305 height compared to the scrollview size
		scrollPosition = GUILayout.BeginScrollView(scrollPosition, false, false, GUIStyle.none, GUIStyle.none, GUILayout.Width(Screen.width), GUILayout.Height(Screen.height));

Credits", largeLabel);


wow… when you won the last game it set the time.timescale to 0. In the credits scene I didn’t set it to 1 again…
