Left Joy-Con issues resolved for future units, Nintendo claims
“The manufacturing variation has been addressed and corrected.”
Nintendo claims to have solved the issue of left Joy-Con controllers de-syncing from the Switch, at least for all future units.
"A manufacturing variation has resulted in wireless interference with a small number of the left Joy-Con," Nintendo said in a statement to CNET. "Moving forward this will not be an issue, as the manufacturing variation has been addressed and corrected at the factory level."
That's all well and good for those who have yet to purchase a Switch, but what about all those who purchased a Switch in its first few weeks? It was Nintendo's fastest-selling console in Europe, after all.
Nintendo claimed that since this "manufacturing variation" only affects a "small number" of units, that "there is no design issue with the Joy-Con controllers."
As such, Nintendo said that "no widespread proactive repair or replacement effort is underway."
If you're affected by this problem, Nintendo urges you to reach out to customer support to determine if it's a hardware issue. After all, it could be caused by aquarium interference.
But if it is determined that your controller is faulty, Nintendo will fix it. "Consumers can send their controller directly to Nintendo for the adjustment, free of charge, with an anticipated quick return of less than a week," the hardware manufacturer stated.
"We have determined a simple fix can be made to any affected Joy-Con to improve connectivity," Nintendo said. According to CNET, that fix is none other than a smidge of foam.
