The Samsung Galaxy Ace S5830 is a nice mid-range Android phone running 2.2 Froyo with Touchwiz 3.0 on top. Although it isn’t quite intuitive, to remove an app shortcut (or launcher) from your phone’s main screen (or desktop if you will) is pretty simple.
Simply locate the app shortcut icon you wish to remove from your desktop screen and then press down on and hold the icon. As you hold down, a trash can bar will appear at the bottom of the screen. Simply drag the icon down onto the trash bar and release, resulting in the deletion of the shortcut.
And now you know!
