is it still under warranty?

so you bought a second hand controller? i bet that one was OEM version tho. too bad nothing can be done if like that. but maybe you can try DIY fix it. try change the conductive film or something like that (i forgot what was it called lol). last time my old dualshock 4 (1st gen) got a no response prob. so i just buy that thing online for RM20+ and changed it myself. works for a few moth before the battery kaput
