There are a couple of problems I’m having with my new Nexus One smart phone. One is even when all of the windows are closed many of the applications continue to run. To shut them down you have to press the menu button, touch Settings, touch Applications and touch Running Services. Next you have to select the application you wish to shut down and touch stop. You could do all of this or you could install the “Advanced Task Killer” application. You open the “Advanced Task Killer” and touch Kill selected apps. You can also leave some apps running by deselecting them. That’s it! No fumbling through menus. Just two touches on the screen. Killing apps will help save your battery and save on your data consumption.
