TE stick help

So a few days back I realized that my right motion on my stick isnt registering when i try and fadc… the double tap right doesn’t register. Regular dashing will register sometimes (registers better when im not inputting a focus attack). So I’m curious as to what the problem may be, please help!

Also how will they know I voided my warranty if i open up the top of it (haven’t yet but if its an easy fix i’ll do it).

Thanks everyone!:lovin:
