The Steam Deck was released recently and some users have reported drifting problems with their thumbs.
Most of the users reported the stated issue mainly focusing on the right thumb.
According to Valve, the problem stems from a dead zone correction issue introduced in a recent firmware update.
The company submitted a fix to address the issue. To download the update, you need to go to Settings > System > Software Update.
The Steam Deck launches on Febraury 25 after a shortage of materials prevented the handheld gaming PC from launching in December as planned. Valve said as recently as next month, production will be at “hundreds of thousands,” meaning many people will be able to participate in them.
In our review, Alex called the system “a technical wonder” and “when it works,” it’s a “really powerful proposition that could open up PC gaming and PC exclusivity for more audience who don’t want a gaming laptop or giant desktop.”
Our review goes on to say that through software updates and game verification, the final launch iteration will be “brilliant” as the current can sometimes be buggy.
