GameSir X2s LT Set off downside

Howdy, I used to be doing guide calibration to repair the LT set off as a result of the sunshine turns from blue to white every time I press it. I attempted resetting the controller after which recalibrating it many instances, but the issue continues to be there. Any doable options can be appreciated, thanks!

Btw, I solely had this controller for lower than a month.
