Do you have info about led blinking and the meaning of it?

@sebastianc37681 If your controller is one of those DualSense controller that was shipped from Poland, then there is a known issue with those. The 3 blinks are indicating that there is a connection issue on the inside of your controller. Time to open it up and to make sure that all the ribbon cables are properly seated and that there is not anything that can create a short etc, Once open take a couple of good pictures and post those with your Question. That way we can see what you see.
