I've uninstalled the apps I don't use, have a cache cleaner and use netqin security in which I can use the task manager in there to free up memory. How comes even when the internet connection is off I get warnings that my memory is too low? It says my memory being used is around 350mb/650mb, sometimes up to 80%?!?! When I clear the running apps it still only goes down to 55-60%. Is there anything else I can do?
