Nintendo has addressed the wireless issues stemming from the Nintendo Switch Joy-Cons and have told Kotaku that they were caused by a ‘manufacturing variation.’ The issue seems to revolve around the left Joy-Con which is causing some people a bit of a headache due to disconnection problems. The company has informed the publication to contact them for a fix if you’re experiencing problems. Here’s the statement provided to Kotaku:
There is no design issue with the Joy-Con controllers, and no widespread proactive repair or replacement effort is underway. A manufacturing variation has resulted in wireless interference with a small number of the left Joy-Con. Moving forward this will not be an issue, as the manufacturing variation has been addressed and corrected at the factory level.
We have determined a simple fix can be made to any affected Joy-Con to improve connectivity.
There are other reasons consumers may be experiencing wireless interference. We are asking consumers to contact our customer support team so we can help them determine if a repair is necessary. If it is, consumers can send their controller directly to Nintendo for the adjustment, free of charge, with an anticipated quick return of less than a week. Repair timing may vary by region.
