Hi guys,
Im really new to Android since Note 2 is my 1st android phone (i juz have bought it for 2 days). I have some questions that really need the answers.
-When i hold the home button, there is a garbage icon so what is the function of this one?
-In the task manager, there are 2 options that i really dont know what is the difference which are "end the active application" and "clear ram"?

Thank you so much.
