Answer to "Why is my PS4 controller acting on its own?"I was having this problem for a couple weeks. I had recently switched my setup and i had my tv on top of a metal filing cabinet with my PlayStation behind the filing cabinet. My girlfriend suggested that the metal could be causing an interference. I moved my setup around and now it works normally. I hope this works for everyone and not just me but I would try to remove anything in between you and your PlayStation so that there is a direct signal from your controller to the PlayStation. Kinda like a difficult tv remote. I hope this helps anyone.
