I too have a SGS4. The thing quits quite a bit so I usually use my Nexus 7 instead. About the task killer, the SGS3 is a pretty powerful phone so it doesn't really require a task killer. Just go to developer options, and scroll down to find "background processes." I usually have my settings set to "No Background processes." The annoying part though, is that the option resets itself after each reboot.
