Samsung...Galaxy S II? I thought PS Touch wasn't supported on smartphones; only tablets?
Not sure what's causing the top toolbar to slide away; it shouldn't go away unless you want it to (usually via the hide all toolbars button in the top right).
Its normal for all the tools and menu options to disapear temporarily when going into the tranform mode (except the transform tools along the bottom). After you hit the blue Done button to complete the transform operation they all return.
