Some say apps run in the background or something like they just don't end or die when you hit home? Please explain and how I can fix or help this problem
It's ok, the phone and OS is designed this way. When Android needs more memory it will drop out whatever isn't needed. There are task killers for those who want to manually kill tasks but a fair number don't believe it helps and that it can actually slow down performance. "Let 'em run" is this responder's opinon.
If you apply a rom or theme - backup first!
If you don't know how to backup...Stop until you do.
hint: I name my backups like this: sg6.0_20100428 or ss4.2_20100626 to easily find them later. rom and date.
