Generally, programs or applications on Android there is no menu or exit to exit, we often open or run other applications while the previous application still works or not closed, or let it run in the background, of course this will affect the performance of the device itself because unused memory will be more. It make a difference if the program is not used in close or closed first.
To Exit / close or terminate the application on the Samsung Galaxy Tab, we go to the Task Manager
Press and hold the emblem / logo home about 3 or 4 seconds
So then the Task Manager window will appear, we live to click the X on each of the applications that we will cover, or to close all applications, we select End all
Another way to get into the Task Manager is to press the logo / mark ^
Then we select Task manager menu
