I use the Samsung smart manager widget it will show a pie chart of your ram, battery, storage and then you can just click the ram pie chart and it will show you the list of processes using your ram and how much.
Amazing that we pay this money for these devices but yet they are so limited because of these carriers. Is there any good apps for management like that?
It's at the top part of the screen. Silly those other carriers disabled it.. its a good widget. They probably already have their own carrier version of the widget and want to push that on you all instead....
