Why Microsoft doesn't fix a bug that give input issue with Xbox Series X controllers on...

Apologies but you are not understanding me.

The scenario goes like this:

Purchased xbox series controller;

Connected and updated series controller on laptop;

Attempted to play a game on laptop;

Controller input is not present;

In some games the controller doesn't appear in the setup;

In some games the controller registers but the inputs are incorrect, sometimes the z-axis registers as a button (x button) and not a movement;

Connected controller to tablet and mobile phone and controller input is fine;

Is the problem my games or my controller firmware not syncing with the games?

Is there a fix?

On Xbox Series X when some games like Doom Eternal, Crash Bandicoot 4, Psychonauts 2, Tales of Arise and Visage are launched (only Xbox Series X enhanced games and not all of them) any Xbox Series X controller incur in an input issue, with battery and with USB cable without battery: if any key or trigger is pressed rapidly it doesn't work, a sort of input lag. The issue persist in any dashboard menu, then if I turn off and turn on the controller again the problem disappear until I return to the game in background that caused the issue. Any Xbox One X controller works perfectly instead. Both Xbox Series X and Xbox Series X controller are update with the latest update. I noticed that when the issue start the usual buzzing noise of the controller change sound, a lower sound. If I plug any headphone with or without microphone in the Xbox Series X controller the commands are more responsive but the problem remains. I reported more and more times this problem to Microsoft since 3 months but still there isn't an update that resolve this issue with my great disappointment. I think this issue started since about 4 months after a system update, and I think the problem is the same of yours. Can you confirm this?

It's probably a bug. For some users they have been shown the Xbox One instead of the Series X. I'm sure Microsoft are aware of the issue, and will be fixing it asap.

I have an issue similar to yours and identical to other users: even after OS update 10.0.22000.2656,

I have reported many times this issue and it has been reported by other users too.
Analog sticks and triggers calibration from the system menu is missing, an essential feature in my opinion, I'm reporting this since 3 years.

My Xbox Series X controller has been giving me sensitivity and joystick issues too, but from what I can tell? The firmware on these new controllers is bugged to hell. I’ve seen reports identical to mine, and now that I’m reading this, I’m curious about what they’re doing to fix it. Like you, I’ve had to resort to just using an Xbox One controller.
