What's this weird symbol?

[Guest The Alpha Gamer]

All i did was plug it up to my computer an put a file on the memory card, and that symbol's been there since =/

Is your phone in vibrate-only mode? Try turning the phone volume up and it should disappear.

It's the vibrate icon, I think it looks a bit different because of your theme.

BTW I like your homescreen.

Definitely the vibrate symbol.
