What you see above is the faulty Joy-Con CNET author Sean Hollister sent to Nintendo for repairs. Hollister said he took his Joy-Con apart and photographed the inside before he sent it off for repairs because he wanted to see what fixes Nintendo would employ for the issue.
Surprisingly, the Joy-Con came back as the exact same one he was sent, so he was delighted to open it up and see the fix that Nintendo came up with.
Can you spot the difference? Having trouble? Look in the lower right corner of the bottom picture to see the difference. There’s a small black piece of foam that’s been added inside the housing of the Joy-Con. CNET says the small piece of foam is likely conductive foam so it can shield the Joy-Con’s antenna from RF interference.
Sean admits he took the small block of foam out of the repaired Joy-Con and the device was immediately back to its old problems of disconnecting frequently, so it does seem like this will be the fix Nintendo employs with all future Joy-Con shipments.
Now that we know the fix Nintendo is employing for these, who is going to be the first to buy a sheet of conductive foam from Amazon and open their Joy-Con to fix issues themselves?
