Marcelo Marques, that is the sign of a wore out analog controller. You will have to replace it. The controller is available at places [http://www.aliexpress.com/item/Original-Analog-Sticks-Controller-3D-Thumbstick-Replacement-Parts-for-PS4-Dualshock-4-Controller/1845122997.html|like this] This will require to unsolder the old one and then resolder the new controller. Hope this helps, good luck.
