That design makes it appear flawless. Tidy. Symbian (the normal Nokia OS these days) does similar auto shutdowns to recover memory, but doesn't automatically restart anything, and they're gone from the task switcher. Do kill apps in Android show as still running in the task switcher?

I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question."

Kill_ed_ apps, I mean. J -- "If this crazy idealistic 'dont-eat-people' idea of yours was to catch on, I just don't know where we would all be. Fortunately, I suppose it catching on isn't really very likely -- why, you might just as well go around saying 'Don't fight people'..." -- Flanders & Swann

This is how android does it. Android does not auto-restart the app, it's just where you last left it off when you open it again. > > Do kill apps in Android show as still running in the task switcher? > > Cheers - Jaimie Neither do the killed off apps show up in the task manager. I really am curious to know if there is someone here who can explain the inner working of the iPhone OS to me? I'm very interested in how it works. :)
