So I am having this exact same problem as in the link above (right quick turn functions but the left quick turn does not) and my PS4 is only three days old so I know that the controller is in great working order. I am only able to quick turn to the left when I force the stick down as when pressing R3. I understand that my controller could be slightly off but I have not had this issue with other shooters on the same DS4. If anyone knows how to fix this problem please let me know. I have tried everything suggested in the attached forum, still not working. I think that if Bungie gave us an option to either calibrate the quick turn area or maybe just expand it this problem would be a non issue, or if the sensitivity were gradiated all the way to the edge of the stick reach instead of having the small jump at the end that would work as well. P.S. This sucks for multiplayer. Whats worse is every time I get blasted while turning and say anything about it, my fiancé quotes Zoolander lines about me not being an ambi-turner, so please help me before i am severely shamed.
