JDM040 L2 will make LY go up

[alexzai89]

Hi guys,

I have 1 DS4 having this weird issue where when i press Left Trigger (L2), the left joystick move up as well.
if i press left joystick, it work fine but when i press the left trigger, the LY go up as well.
it's not go up all the way when i press the trigger, if i press the trigger in 50%, the left joystick also go up 50%. if i press the trigger at 30%, the left joystick also go up 30%
meaning the left trigger value is reflect to left joystick up as well.

anyone know what the issue that causing this problem?
Thanks in advance.
