I'm not sure if I'm in the right place asking this but I downloaded advance task killer because it was rated high ppl seemed to like it and suggest I ppl to download it b/c it saves battery, I can tell a difference but not sure if its great enough to keep the app but the thing that bugs me is I'll kill apps and go back to home screen and go back in ATK two seconds after I just killed everything and voice and settings are running again sometimes others but mostly those two when I kill exit and go back in real quick and sometimes it says apps are running I've never used like amazon will b running I've never opened it, wats this mean, it seems like atk isn't working or my phone is screwy or something, any advice?
