I was browsing vids about vita shoulder button problems when I came across this: That seems like it's worth doing. My Vita is a 1000 not a 2000 but the method demonstrated in the vid should work regardless. I dunno about you all but I love responsive buttons! Also, maybe this will help solve the creaking noise the L button makes. The creaking is annoying and I've decided to fix it at any costs. If I can remove the top screen of a 3DS XL then I should be able to stop a creaking L button.
