Many programs or applications on Android do not have the Exit/quit menu. We open or run other applications while the previous application still works or not closed, or leave it running in the background, this will affect to the performance because memory in use will be more.
Would be different if we close the application that not used first before opening next application.
To Close or terminate the application on Samsung Galaxy Tab, we go to the Task Manager
Press and hold the home logo about 3 or 4 seconds
Task Manager window will appear, then we just click/tap on the X sign of each application that will be closed, or to close all applications, tap the End all
Another way to show the Task Manager is by tapping the logo / sign ^
Then select the Task Manager menu
