タイトル Galaxy Note Pro display problem
本文
Hi
I'm Taro Yamada.
I've just received Galaxy Note Pro which was sent from B&H to me(Japan) .
And I noticed that there is a black splotch in the left bottom of display.
I tried to wipe out surface in order to remove it. But it doesn't disappear.

I hope to exchange the product.
Please tell me what choices I can take.

Thanks.
