I know I know, another one of that topic 
But my issue is different... Bought a new 3ds normal version, played with it, until yesterday I horribly realized that something was moving inside the console, even when lightly shaken.
Found out the problem come from the circle pad (the actual one, not the C-stick), since when I tried shaking it with the circle pad pressed in a direction the noise is gone.
Now, here's my question: is this normal or I have a bad unit? Thanks in advance to everyone!
