A bit of black foam has fixed the Switch’s Joy-Con issues

2 min read


The Nintendo Switch is out, and it’s a great little system that completely delivers on its promise of putting home-console quality games in your hands. Unfortunately, it seems that many units suffer from an issue that makes the left Joy-Con intermittently stop responding. It’s something that I experienced myself, though moving the Switch away from my Wi-Fi router seems to have alleviated the issue. For a while, I thought that it may be placebo, but it turns out there may be interference issues.

It seems that there’s a simple, cheap and relatively easy fix available for the issue. People who live in countries that have the support are able to send their desynching left Joy-Cons to Nintendo, who fix it and send it back. That’s precisely what CNET did – but they took pictures of the unit’s guts before and after repair.

Nintendo seems to have fixed the issue with a little bit of foam rubber. According to CNET, Nintendo stuck a bit of conductive foam over the left Joy-Con’s Bluetooth antenna. CNET says that it’s “foam that’s been specially treated with nickel, copper or both so it can shield electronics from RF interference.” It seems to have done the trick.

There’s good and bad news there. The good news is that it shouldn’t be at all difficult to apply this fix yourself at home, should you be able to find a bit of conductive foam. The bad news? It means opening a Joy-Con and voiding your warranty. It also means that it is indeed a hardware issue, and can’t be fixed through any sort of firmware or software patch.

CNET’s also suggested that Nintendo’s fixed the issue in new standalone Joy-Con hardware, and very probably the new Switch units that are being manufactured.

Editor. I'm old, grumpy and more than just a little cynical. One day, I found myself in possession of a NES, and a copy of Super Mario Bros 3. It was that game that made me realise that games were more than just toys to idly while away time - they were capable of being masterpieces. I'm here now, looking for more of those masterpieces.
