My LB button on controller is too responsive?

Is there a question there ?

Whats "taking the controller from their stock." got to do with anything ?

Maybe too much pressure is applied to the LB button.

The problem with my LB button working as RB button is on my Xbox series x controller

I've got a floppy LB button on mine as well. Already created a replacement order, but I only have one controller (and only NEED one controller in my household) as well. And as I'm still waiting on my advance replacement for my console I'm not too excited
about sending off my one controller for a replacement.

Try pressing and holding the little circle button in between (LB) and (RB).

There should also be one on your console, press and hold that too. It should sync your controllers to your Xbox 360.

Hey, I’ve had a very similar issue over the past couple of days. My favorite game is Rocket League, I play it all the time. When you are in the air, you can tilt your car left or right by “air rolling”. I had this “air rolling” command bound to my elite
series 2’s LB button. That LB button just recently started acting up. I would jump into the air and it would take a half a second to actually start air rolling. I went to the xbox accessories app and tested the LB button. Sure enough, it took a second to actually
register the click. This controller is extremely expensive, and my warranty ended a few months ago, so i started looking for a fix. I came across someone saying,”blow into the hole between the bumper and the trigger”. Several people were saying this. I didn’t
think it’d work, and I was correct, it didn’t..by itself. I then tried rapidly pressing LB while blowing, and it seems to be working properly now. Hope this helped. I’ll be updating this response if the LB button decides to stop working again. If you are reading
this and do not see another response from me, it’s still working . Best of luck!
