L2 PS4 controller issue

[Lyshell]

Its 100% the controller, when I used to play on the PS4 I used to suffer from this when I used one of my two controllers (I would cycle them when I needed to charge them) I ended up just using the controller that never experience the problem. I forgot about it one day and used the funky controller and lo and behold, that annoying problem was there. Time to buy a new controller.

I hope it is and I hope it's not the case. Because if it's just the controller I would gladly buy a new one, but just don't want to buy a new one and have the issue persist, you know? And it's hard to gauge that it's the controller because this issue doesn't arise anywhere else. And it's not like the button doesn't work because it is responsive but it's just weird that it randomly makes the character walk and no other kind of glitches.
