Summary
~~~~~
Whether you love it or hate it, the Steam Deck has a built-in sensor that feeds the software data based on the movement and orientation of the device.
And while few of you are likely to be using motion controls in every game, it can be helpful to help zero into an enemy while aiming in a first-person style game.
But sometimes that data ends up to be less accurate than it could be.
Thankfully Valve has a feature in Steam OS that will help you to calibrate the gyro sensor inside of the Steam Deck.
We can find this by pressing the Steam button on the left side of the deck, here.
Then selecting the Settings menu.
From here, scroll down again so that we can see the Controller menu.
And now you will have access to the Calibration and Advanced Settings software.
Let's select the Gyro Calibration feature on the left-side of the screen here.
And right off the bat you should be able to check the status of your Steam Deck gyroscope.
The pitch, yaw, and roll data will be reflected on-screen and you will be able to monitor it while moving the Deck around.
This is also a way to double-check to see if your device has any drift-related issues.
But even if you haven't noticed any issues, it's likely a good idea to tap the Calibrate button right here.
Doing so will begin the Steam Deck gyroscope calibration process so be ready for it.
Once it begins, you'll have 4 seconds to set down the Steam Deck on a flat surface.
Let's go ahead and calibrate this device right here.
Now that the software has finished its calibration tests, we can check to see if things are actually fixed.
If you noticed the drift issue from this raw data page, it should be easy to spot it has been fixed.
But if you first realized there was a gyro issue in a specific game, then go ahead and load one up and give it a test.
If you're still having gyroscropic related issues then it may end up being hardware related.
I would then try to re-image the Steam Deck before contacting support at Valve in hopes that they have a fix available to you.
They will likely initiate an RMA if it's still under warranty but they also have a repair service that you could hire.
