Hi wanna ask, I don't own a s4 so I wanna ask those who is using it, do u use the soft home key features like the one found in iPhone?

If u can read Chinese, maybe u can go to this website http://www.mobile01.com/newsdetail.php?id=13296 n scroll to the bottom then u know what I mean..

I asked here is becos I seldom c any review mention abt it
