Xbox controller analog stick unresponsive in one direction

My name is Loren. I'm an Independent Advisor and I'll be glad to help you today.

Did you make sure that your controller is updated?

I want to assume that you're describing a "drift" in the controller analog stick.

My very first controller experienced this after playing a lot of BF4. In order to run, you had to press down the analog stick, many times while holding the analog stick in a certain direction to keep moving.

If this is present the PC settings will show as if you're holding it down in a slight direction at all times when left sitting. You could attempt to have the controller replaced..... myservices.xbox.com

Might be a controller issue. Very used controllers tend to get the analog to stick a bit to one direction. Try to Roll both Analog sticks to sort of unstick and recenter the analog sticks. Or better yet replace the controller for a new one. Mine sometimes
get stuck a bit to the right and my character looks to the right very very slowly.

In MW3 try to adjust the look sensitivity to the lowest possible setting. If then your character slowly looks upward to the sky then i guess the analog sticks need repair. Adjusting the sensitivity to a higher setting will make your character look up to
the sky way faster than the lower sensitivity settings. This is a clear sign of old controllers that needs replacment. If ever your controller is still new then hopefully you can exchange it for a new one.

Okay,

After letting the analog stick go, the camera keeps panning to the direction that the analog stick was originally placed?

Drifting one direction. I can clearly see the stick get stuck when moving the analog stick. It doesnt reset to the middle. Ever. Disappointed. Fustrated. Using my old controller after the joy of receiving a new one is just a let down..
