Joysticks: Probably Still Drifty
Joy-Con joysticks use a potentiometer to read the voltage at a wiper that slides across a strip of resistive material. That material wears down over time, or plastic and dust can dirty the sensors.
Stick drift is a huge problem with other Switch models. One survey found that 40% of Switch owners had problems with their Joy-Cons drifting, and things didn’t get any better with the Lite or OLED editions. After a bunch of lawsuits, Nintendo’s president even admitted it and apologized, setting up a free repair program for customers in some parts of the world.
Disappointing to say the least.
My wife loves the switch but has gone through 3 or 4 different sets of controllers. I tried my hand at repairing one of them and it was not fun – to put it mildly – and I do not savor repeating the experience. I honestly did not know there were hall effect replacements for the original joycon sticks, and wish I had known that when I replaced the one I did.
