The first is with the xbox controller that was included with the system. The left stick loves freely moving and choosing things in-game with so much as the slightest touch. For instance, a fighting game, it'll randomly go all over the character roster when I try and select just one character.
The second is with another xbox controller I purchased when the first one began messing up like that. The right stick doesn't seem to want to snap back into where it's supposed to, and is currently resting as far up as it can go, refusing to get fixed.
How would I go about getting both of these fixed? Would it be as simple as opening them, making sure I don't lose the buttons, and very carefully cleaning them?
