I have a very weird and irritating mark on the screen. It was very disorientating as the top screen is the main screen in pokemon and this mark is highly irritating, and I dunno how to get rid of it. You can see it is covering around 6-7 pixels. My 3DS (not XL) is a month old and is black in colour. Clearly, this mark is not on the LCD, and is on the second protective screen - I know as the mark is projecting a shadow as well. I tried using deodorant and alcohol to remove this stupid mark, but it's not helping! Please help! How do I remove it?
