The most common Steam Deck job by a distance. A character that walks on its own, a stick that reads input you did not give it, or a trigger that no longer returns.

Steam Deck thumbstick and trigger drift repair
Drift is the fault we see most on this handheld. The character wanders with your thumbs off the sticks, the cursor creeps, or a trigger stops travelling properly. It is wear in the stick module rather than anything you did wrong, and no amount of recalibrating in software fixes a worn part.
The modules are soldered to the controller boards, so this is bench work rather than a clip-out swap. We replace the affected module, recalibrate and test both sticks and both triggers through their full travel before it goes back.
