Yes, I have checked for related threads to see if this was formerly addressed. It's been discussed generally, but neither specifically to the CDMA HTC Hero or the procedure I'm going to summarize below: If you press: Home --> and hold it for a couple of seconds You get pictures (icons) of the last six apps you've run. I was in the Sprint store today and the rep who also uses the HTC Hero told me there's an App that stops them, which can be downloaded at the Android Market. It's called " Kill-Something?????? " It's an App we can download that will force these off and perhaps save battery power, or at least stop them from running in the background. Questions 1) Anyone know the name of this App? 2) Is it useful? Have you had any experiences with it either positive or negative? 3) Any other tips (in layman terms please) on stopping Apps from running in the background on Sprint HTC Hero?
