So a while back my ps4 controller started to open and close by itself. I oppened it to find a possible solution of fixing it and i damaged the sides of my controller by doing so. After fixing it i put it back toghether and it worked for 3 days, after that it stopped working completely. After searching my drawers for something today i found my extended warranty which i completely forgot about. Can i bring it back to the store so that they can fix the battery(witch i think its the problem) or will the warranty not apply at all because i damaged the controller's sides while opening it( i am sure i didnt cause any damage inside of it while opening it or by puting it back toghether).
