Hi I just noticed that all 2 new 3ds/ new 3dsxl have sandy grainy circle pads. They are alot less smooth than my old 3ds which I bough from launch. Is it normal? Because they are from different markets. The N3dsXL is from US and the small one is from EU. Is there any lubricant that can be applied to those circle pads? I also need it for my PSP old analog stick. Silicon or anything? Thanks!
