Earlier today we reported that Nintendo's official fix for faulty left JoyCons is extremely thrifty: a small piece of conductive foam. Now the Japanese console-maker has delivered an official statement on the JoyCons, confirming the issues were caused by a "manufacturing variation" that has been corrected. Nintendo also confirmed that no mass recall or replacement initiative will be happening.

"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," Nintendo told IGN in an official statement.

"We have determined a simple fix can be made to any affected Joy-Con to improve connectivity."

Nintendo says that it will determine if their nifty foam-fix is needed, and if it is, they'll fix it free of charge and have it back to you in less than week's time. That's pretty rad.

"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. For help with any hardware or software questions, please visit" https://support.nintendo.com
