So you've noticed your skill level just isn't what it used to be, you've started swerving right when you should be running forwards.
In fact, you've started swerving right when you're stood still too, so maybe it's not you at all, maybe you're suffering from analogue stick drift.
Well, the good news is that you can get that fixed. There are two ways of doing this, one of which is easy and doesn't involve opening your controller up, the other is, well, the opposite.
So, here's how to fix stick drift on PS4.
How to fix stick drift on PS4 with pressurized air
This is the first port of call when sailing a ship that aims to fix your PS4 controller. Step 1 is to buy some pressurized air.
Once you've got your hands on that, you can start the process of fixing your controller. Turn it off first, of course, then use the duster to blow at the bottom of your analog sticks. Move them around a bit as you do so, but make sure to not do it constantly as it can damage the controller if used too much.
After this is done, wiggle your sticks around the full range of motion for a couple of minutes. Hopefully, this will have fixed your issue.

Right, so, and this is important, we do not recommend that you do this. It'll void your warranty and could end up with you having no controller at all if you mess up.
If none of that deters you, then we recommend you watch and follow along with this video:
Again, we don't recommend this method, and you run a few risks by following it. That being said, it could cure the issue you're having. That means you can go back to playing games the way you like.
