WARNING :
- before trying this solution, try cleaning and reseting your controller as explained by other tutorials available all over the web.
- if this fix also works for you, it might only be a temporary (and unstable) fix, and you might still need to replace the defective potentiometer.
Some PS4 controllers move forward when L2 is pressed. Here is a fix.
CUH-ZCT2E
- When L2 is pressed, left Y axis is detected too (move forward)
- Left stick Y axis (forward backward) is unstable ;
Just slightly open the little green thing (about 1 mm)
