Right joystick Pulling up?

br
- in PlayStation
5

It is a dualshock 4 (PS4 Slim), whenever I press / hold the L2 button, the right joystick pulls upwards.

This is a huge disadvantage, especially in shooters.

Sometimes that happens and sometimes it doesn't. When I press L2 through, the pull on the right joystick is greater than when I just tap L2.

I have also speculated that my thumb on the right joystick is counteracting that, but I can rule that out because it also happens when my right hand is away from the controller…

Is there any way to fix this and how do I do it?

(FYI: The playstation and the dualshock are no longer under warranty because this has expired, I also have the tools here to disassemble the dualshock 4)

Ex

Disassemble, clean and reassemble.

In the worst case, the right analog stick has to be replaced.

(Still, it is a strange constellation.)

It is also a mystery to me why the right js drifts when the left trigger is pressed…

I'm only aware of this js drift from my controller, which has already kissed the wall, but has never been thrown here

Ex

First disassemble it and clean it with pure alcohol. Put it back together and try again.

I don't have pure alcohol here…

Is pure alcohol cheap?

Can I find the alcohol in the obi too?

I have compressed air in the can, waiting sticks and nail polish remover

Are the three things harmless or should I really use the alcohol?

Ex

Nail polish remover is very bad, far too aggressive. You can get pure alcohol in the pharmacy. The point is that pure alcohol disappears again without leaving any residue.
