I bought the Galaxy Tab 10.1 to serve as a supplementary reading device. Occasionally i'd run social media, email, news apps. I realise these apps are always running in background to retrieve updates. They auto-launch even from a fresh OS reboot. I do not want that to happen, and only wish to use them when I launch it visually. There don't appear to be settings available for the apps, neither do I observe an OS-level interface to control what to launch or not. Is there an additional control app that is available to configure this?
