The Samsung Captivate is a smartphone that runs on Google's Android operating system. Released in 2010, the Captivate features the Samsung TouchWiz user interface, which means some of its basic functions--including manually closing applications--are handled slightly differently than on a standard Android phone. Devices with the TouchWiz user interface come bundled with a feature called Task Manager that allows you to close applications from the Home menu.
Press and hold the “Home” button on the Captivate. Continue holding the button until the Task Manager application appears.
Scroll through the list of applications currently running on your phone. Each application is represented by a small thumbnail image with an “X” icon in its top corner.
Tap the “X” icon in the top corner of the application you want to close.
