I actually had similar issues that you described early this morning, and I was wondering when it would happen. My fighting game controllers only last about 3 to 5 months, I am very heavy handed and tend to hit the buttons with quite a bit of pressure at times. Sometimes when I hit back, my character will do a jump back now. Gonna try Preon's method to see if it can remedy the problem. If not, I need a new controller. I can't even blame the DS4, it's just me...I've always busted them quickly, and to think, this bad boy has stood the test of over 2,000 matches on PS4.
Appreciate that advice, Preon.
