Re: how to close window on this android

Welcome to Android Central! Which device do you have? It is probably referring to open tabs in your browser. Open your browser, and tap the tab icon at the top of the screen (usually looks like two rectangles linked together). This will show you all open browser tabs. Close them all, either by tapping the X in the upper corner of each tab, or by swiping them away.
