As we install applications on our Galaxy Tab, finding a particular one on the home screen becomes more difficult. To avoid wasting time you can use the search button (the little magnifying glass), located at the bottom of the tablet.
But first you must go to Search Settings and verify that the search option will also handle applications
In the Home screen, click on "Settings> Search> Items to search"
Check the checkbox to the right of "Apps" is selected, if not select it
Onwards to find an application, press the search button an then enter the name of the application in the search box, if installed on your device, it should appear in *the list of results.
