had my galaxy for a while now and bot sure when or what has happened but I have no idea how to change the apps on the home screen.. I've done it before since I have my CBA banking app among others that I've put there previously. now when I try to long press an app from home screen to drag down to the bottom row, the whole row is replaced with a trash can. any help would bw awesome since I've deleted an app from there and can't get any back. its like a missing tooth. to help with any suggestions, I can't long press the bottom icons either, they remain unresponsive. please just tell me I am missing something simple, I'd prefer to slap my own head than need to slap Samsung's again.
