Connection with the joystick is weak.
Long ago I opened the ps4 slim for simple cleaning. After that I started having problems with connecting the joystick to the console. I basically can't use it if I stay more than 1 meter away from the playstation. It is as if I had disconnected the receiver that communicates with the joystick even though it is connected "correctly". I would like to believe that I did not damage the receiver.
