Just as mentioned vaguely in the title, my N3DS behaves weirdly. And it happens noticeable more often when charging it. Whenever I use it, sometimes it boots up with no sound and a numb touch screen. But the real problem is, even after calibrating my control stick, the 3DS behaves as if I input the same direction periodically. What can I do against it? No, I didn't stick a dime under the control stick, IIRC, but I surely did that on my old 3DS back then (with a blacked out top screen...) and it didn't affect it really. (Just made breeding Pokémon easier...) It all started back when I used tubehax for the first time, for a New Leaf town. Now, not only that ugly scratch at the top screen, but the high self esteem of my N3DS are a big nuisance.
