Two seemingly dumb questions

[zyonasan]

I searched for my problem before creating this topic and couldn't find anything.

with that said, I just got my 32gb S9. I'm really liking it so far, I got the latest firmware (2.41) and everything is running smooth. However, i'll have to get higher quality headphones...lol.

anyway.....

QUESTION 1: Do I have to hook the s9 up via usb everytime I want to delete data from its drive? for some reason (even after highlighting a song/video I want to delete) the "X" or delete icon is "greyed out" as if its not functional.....

Question 2: How do I go back to the default black background? put a wallpaper up that I kid of liked, but I want to keep it at default for a little while longer. There doesn't seem to be an option to get rid of it? is there?
