The left analog stick for my 3DS is a bit unresponsive now, I can barely play games like Smash.

A while ago I accidentally popped out the rubber pad during a Smash game, then glued it back but over time I think it slowly became less sensitive, though I'm not sure if it's the glue or a hardware issue hindering the analog stick detection. Never really noticed it since I pretty much been playing MH4U since Feb shortly after incident, and MH doesn't exactly demand precise input.

Is there anyone/place that handles 3DS repairs?
