I have a problem that my R2 and L2 button doesn’t spring back. I was opening it up to fix L3 button but now I have problem with R2 and L2 button..
If you have had your PS4 controller for awhile the springs metal loose their tension. You can get replacement springs. Ebay, amazon, etc. Youtube video shows you how to do it. https://youtu.be/aU9zNsDP9wE DualShock 4 CHU-ZCT2U L1 and R1 Buttons Replacement
My springs look different and so does the inside where they should go, i’m havung trouble finding any visual resources at all for what my controller looks like and can’t seem to figure it out on my own. Even lost a spring in the process and had to order replacements. Can you help?
