Like many my Dual Shock controller PS4 4 (white) has malfunctioned: the left stick did not work even though I rarely used this second controller ... but at least I did not have the problem of rubber or L2 which ... finally squeaked on this controller that! A problem both Sony's enough.
In short, quickly and intensely use your joystick in the first months to see if it suffers a fault and to exchange because the defects do not always appear immediately.
