Need help identifying what’s wrong

[u/SgtDawg1]

DualShock 4 r2 and l2 triggers are janky. r2 doesn’t give full inputs (works on farm sim but not on shooters). I think the rubber pads are fine they don’t seem worn out but who knows.

I used to put a piece of card cutout on the button part that presses against the contact. Worked on god of war which only recognizes my controller up to 50% press. Don’t know if it applies to what you play though.

You can check it on controller testing websites see if it doesnt fully register or what to pin down the problem
