Hi, I just received my new samsung galaxy cell phone. I am still exploring it. Each time when I open an app, then I hit the bottom button to close it, that window (or app) is not really closed. The window just disappears and the app is now running on the background. When you hit another button (the one with several windows) on the bottom, all the windows will pop up. I have to click "X" one by one to close every window. Is there a way to close every app or window with one click or button? I mean, when I click on the window or hit a "close" button, that window or app will be closed. I don't need to click on this button on the bottom and close it one by one. Thanks. Sorry, this is a samsung J5.
