Joystick drift when using L joystick

To address your left joystick's resistance to the left and subsequent rightward drift, you should first try to clean the joystick with compressed air or a small brush to dislodge any debris, then update your controller's firmware. If these don't work, the problem is likely caused by internal wear on the potentiometers, which may require internal cleaning, replacing the thumbstick module, or professional repair.

Replace both left and right potentiometers with hall effect ones.
