why scrollView is not working smoothly in some of android devices?

Question

I am working on an application which is using scroll view. In some devices scroll View is working fine But some devices like HTC desire (which are using lower versions of android) is not smooth in scrolling. layout is using check box in the bottom (margin 20 dp from bottom) and when I try to scroll from that particular area it is not working but in other device like micromax A110 it is working fine... why is it happening any Idea ?

Thanks
