I have a brand new DS Lite and the spring on the R button feels much weaker than the spring on the L, and it feels like it travels a greater distance before it clicks. I spoke to a very kind Nintendo representative who made a special repair order to have the springs and actuators replaced so that I wouldn't have to replace the whole system, on which I had already installed a Zagg Invisible Shield and genuine Hori Screen Guards. Unfortunately, I just got the system back, and while the repair order file says they performed the replacement of those parts, the L+R buttons still seem to have the same problem. Do many people have this problem with their L+R buttons? I find it very strange that the new parts seem to exhibit the exact same problem, it's very noticible and actually very distracting when trying to use the buttons. P.S: The Nintendo representative was very kind and offered to try having the system repaired once again, which is completely awesome.
