Nintendo Switch: Joy-Con drift errors can be fixed quickly and reliably with cardboard
Joy-Con drift has been a thorn in the Nintendo Switch for years now. Anecdotally, two of our Joy-Cons have been affected, both fixed by Nintendo UK for free. Unfortunately, Nintendo is less generous in other countries, and it has made no changes with its new Switch OLED model.
Thankfully, VK's Channel, a relatively unknown YouTube channel, has devised a simple fix for Joy-Con drift that should fix the problem permanently. As the first video below shows, VK's Channel determined that applying pressure between the Joy-Con's Y and B buttons stopped any drifting, which is achievable using a piece of cardboard. The same video also explains why Joy-Con drift may occur, which is worth watching in our opinion. In short, wear between parts causes them to lose contact, which exhibits as Joy-Con drift.
According to VK's Channel, the cardboard fix has been working for two months now. The YouTuber details how to disassemble the reassemble the Joy-Con in the second video below. Please note that while taking apart a Joy-Con is relatively simple, you must remove the controller's battery. Incidentally, several people on an ensuing Reddit thread have confirmed that the fix works on their Joy-Cons.
