So yesterday, i noticed that there was a white or gray-ish pixel in the middle of the top screen. Really noticeable when the screen was dark. Not black and not Red,Green or Blue like a normal Stuck/Dead Pixel i've seen so far. Not dust either, before you ask. Didn't really care about it though because i can't do anything against it anyways. (Not that i know at least) Anyways today, when i booted the console up again, the pixel was suddenly gone. Kinda suprised because i had dead/stuck pixels before and they never went away. What i'd like to ask now, is there a way to reduce the chance of getting a dead/stuck pixel? Currently, my screen is set to 3 (Brightness) because i never really go outside with my 2DS if that helps. Is playing too long a possible cause? Also I heard a while ago, on some other site that rubbing the screen to clean it could maybe cause pixels if you do it too much. Is that true?
