I just got my phone and was messing around with it, as you do, and clicked on "Task Manager". When that opened it showed that all of the apps I had been exploring were still open! I know very little about data usage/RAM usage so I am not sure if this matters? Do apps open in the background, but not actually being used, use my date or is it just an issue of having too many apps open used RAM and can eventually slow down your phone if you have a ton open? I have tried multiple ways of getting out of apps (back button, home button) but no matter what, they still show as open. Is there a way to actually close them other than going to the task manager?
