Hi I've got a xoom2 running 3.2. And its great I am trying to find out what the feature is called when you tap the edg of the screen to move between home screens, instead of sliding, this is a great feature for me and I want it on my is tablet also but I don't know what it called, tried asking Google and motor but neither knew what I was talking about, hope ome1 can help
