The symptoms
Your character walks on their own. The camera slowly spins in menus. The cursor creeps across the screen while the Joy-Con sits untouched on the table. That's stick drift — the most common Nintendo Switch failure there is — and recalibrating in system settings only hides it for a few days.
Why it happens
The analog stick is a mechanical part. Inside it, tiny contact pads wear down and debris builds up with every hour of play, and eventually the stick reports movement that isn't happening. Cleaning sprays and calibration are temporary because the worn hardware is still worn. The real fix is replacing the stick itself.
How we fix it
We replace both analog sticks with new hardware — not a cleaning, not a recalibration — then test every axis, button, and rail connection before shipping your Joy-Cons back. Both sticks, because they've worn together: replacing only the one that's drifting today usually means mailing the other one in six months from now.
Shipping Joy-Cons is cheap and easy
You only send the Joy-Cons — not the console — so they fit in a small padded box that ships for just a few dollars. Pay online, get the shipping address instantly by email, drop them in the mail, and they're repaired within 48 hours of arriving at our Virginia bench.
