Android scrollView no momentum (inertia) when horizontal scrolling

Hello. I've worked before with scrollviews with Android. They always had, like iOS, a momentum when I release my finger from screen. But now I'm working with SDK3.4.0 and Scrollviews in Android don't have inertia when I scroll. Is it a bug? Is there a new property? This is my code:

<ScrollView id="scrollView" top="20" layout="horizontal" scrollingEnabled="true" scrollType="horizontal" height="100" showHorizontalScrollIndicator="false" showVerticalScrollIndicator="false" height="120dp" width="Ti.UI.SIZE">

<ImageView id='i1' height='90' width='130' left='11' />
<ImageView id='i2' height='90' width='130" left='11' />

    -- etc ---

</ScrollView>
