In the Xbox menu the selection slides down on its own, or your character keeps walking after you have let go of the stick. That is stick drift: a worn stick that passes on a movement that is not there. It can occur on the Xbox Wireless Controller of the Series X and Series S and on the Xbox Elite Controller Series 2.
FIXNOW repairs this in Antwerp and Wolvertem. We make the diagnosis first, and we agree on the price before the work begins. On the Xbox Wireless Controller you have two options: one stick or TMR sticks. You can also send the controller in yourself, with track & trace.
