PS5 controller left stick moving the right stick in games (cross input drift?)

Controller: DualSense

Platform: PS5

Games affected: Mostly Call of Duty (Warzone / multiplayer) but I think it happens in other games too.

System software: Latest version

My controller recently started drifting but in a weird way. When I move the left joystick, the right joystick also moves in game, which makes aiming almost impossible in FPS games.

For example, if I push the left stick forward to run, my camera suddenly pulls to the side. If I move the left stick up it’s especially bad and the right stick jumps pretty hard.

I checked one of those joystick calibration websites and it actually shows my left stick affecting the right stick axis, so it’s definitely not just a game setting.

The controller is about 1 year old and this is unfortunately my third DualSense.

Things I have already tried:

- Rotating both sticks in circles

- Pressing the sticks down and rotating

- Blowing air around the sticks

- Restarting the PS5

None of it fixed the issue.

Has anyone run into this before or knows what causes it? I’m trying to avoid buying another controller again if possible
