Hey guys. So I just got my first smartphone, a Samsung Galaxy S through US Cellular (the Mesmerize). It runs Android 2.1 Eclair, and is supposed to be updated to Froyo before the end of the year. When I got the phone, the person at US Cellular installed Advanced Task Killer on my phone and said I should use it to free up memory and save battery life. So at first I was using it, and it did free up a lot of memory when I pressed the kill tasks button. But then I had some issues like Winamp getting killed when it was playing music in the background. This prompted me to look more into task killers and I found a lot of conflicting information. Some people say they are bad and don't help and cause trouble on the phone, others said just the opposite. There were some specific comments about ATK saying it can corrupt the OS. This all made me very nervous and I'm not sure what to believe. So for now I have uninstalled ATK. What input do you guys have about task killers? Any tips or recommendations?
