My controller sensitivity is very high on xbox dashboard

You may need to Update your controller firmware.
A new update was released recently.

Hello Joshua,

Thanks for coming to the forums. We understand having issues with sensitivity on the controller. You can configure all this in the accessories app. Here is a

guide for the accessories app to help you.

Left and right stick sensitivity - Select
Left stick or Right stick to customize and control how each stick responds during gameplay. Once you've chosen the stick you want to customize, you can select
Default, Delay, Aggressive, Instant,
or Smooth depending on how responsive you want the stick to be in your game. For example, if you want the controller to respond faster over a shorter stick movement, select
Instant. You'll see a graph that shows you the response curve of the stick.

Note Depending on the game you play, these settings will have different responses. One way to test your settings is to set Slot 1 to
Default and Slot 2 to your customized setting.

Hope this helps.

Brad

I don't have an elite controller and its not for games it's for the main menu of Xbox.

Edit: I think I have discovered the issue and its disappointing. It looks like my controller is suffering from 'stick drift' which is upsetting as this controller was a replacement directly from Xbox for a controller that broke under warranty. I've only
had the controller for about 4 months.
