My R2 button on my Dualshock 4 is stuck when I plug the controller with a USB. However when I use it wireless, the R2 button just doesn't work. I've tried cleaning the motherboard, cleaning the conductive film, switching membranes (switched L2 and R2 membrane, nothing changed), removing the spring etc. etc. I tried almost everything and I'm at a loss. Is it just a dead motherboard?
Pressing R1 seems to input R2 when using wireless mode. Also when in wired mode, the R1 button does not work. R2 is "pressed" indefinitely.
