    </Grid>

The Screen automatically goes back to its previous location and the scroll is not complete. It just moves down and than back again like an elastic

Your Grid, that is the only child of the ScrollViewer, has a fixed height of 1768. That determines the maximum area that can be scrolled up/down by the ScrollViewer.

Your ScrollViewer stretches to fit its parent by default. That parent is another Grid that also has a fixed height of 1768.

Therefore the ScrollViewer has a fixed height of 1768 as well, so there is nothing to scroll. The amount available to scroll is the difference between the ScrollViewer height and the content height. In this case the difference is 0.

Remove the fixed height of the outer Grid. I doubt your Windows Phone has a 1768 high screen :)
