X button on controller stopped working

It sounds like you need to sync your controller to the console.

I would power cycle the console as well. (Hold console power button down for 10 seconds)

Heya I Fresh 23 I!

Sorry to hear about the controller troubles. If there is physical damage with your controller then a replacement is going to be your best option. Please make sure not to bump older threads, as this particular thread was created in 2014. If you'd like some
troubleshooting assistance please create a new thread, we're happy to help out

There has to be a problem with these. My first controllers' LB button never felt right, then got worse over time and became extremely inconsistent. Then the RB button on that same controller gave out completely without warning. So I bought a new controller
only about 3 months ago, LB button worked fine for around 2 months, and now it's inconsistent. I do not beat up my controllers at all so it's not me.

I'd would be nice if Microsoft could at the very least, make a repair kit with the security wrench and shoulder buttons available for purchase.

Mine hasn't stopped working as of yet, but it isn't as responsive as a 3 month old controller should be. The quality of their controllers and mics are very suspect.

I expected better quality. I too have a shoulder button that has stopped working ( the right) and I have only used the system 3 days. That's starting from 12-24-2014. Mine is under warranty and I am going thru the replacement process but I am a bit *** that
my free trial of Xbox live will expire while this thing is in transit. Basically I got it 3 days and they say 10 business days so maybe before next month I can hopefully use my system.

I am an IT person I tested this issue with other apps and it still failed. I also don't have kids so it's not like anyone else abused it and I am pretty careful with my stuff. I was hesitant to get an Xbox after all the issues the 360 had and I also waited
a year for the bugs to get worked out. Obviously this wasn't the case. Also it may be worth mentioning I had run the update for the new firmware for the controller prior to this issue. But that was the second day of ownership.
