Left Joy-Con in particular appears to have reliability issues on unpatched Nintendo Switch consoles.
With just one week to launch, a number of people in the gaming press who have received the Nintendo Switch early are reporting connection issues for the Joy-Con controller, specifically the left controller.
The video below showcases the issue, which appears to be occurring when the Joy-Con controller is covered or something is between the Joy-Con and the console. However, that’s also when intentionally attempting to replicate the issue, so it’s not immediately clear if that is the only time it is occurring.
You can check out some other reports of the issue below.
I've played roughly 20 hours of Zelda and it's happened 2-3 times. https://t.co/5sGBotcIjG— Jose Otero (@jose_otero) February 23, 2017
It happened to me both on the Grip and separately. No clue as to cause. https://t.co/OnxeYsSqrl— Link Link (@nron10) February 23, 2017
Yep, my left JoyCon desynchronizes as I'm playing. Gonna be a big problem if they can't fix this with a firmware update! https://t.co/aCf2K0jOz2— Jason Schreier (@jasonschreier) February 23, 2017
I've just experienced some left Joy Con sync issues with my grey system. Seems to be a universal issue. https://t.co/2wgPe8h8gI— Jeremy Parish (@gamespite) February 23, 2017
I've noticed this as well, happened a few times to me. Assume a software fix is incoming https://t.co/rdJWJYYYRS— Damien McFerran (@DamienMcFerran) February 23, 2017
I'm having issues with the Switch's left Joy-Con dropping sync. I've had to play it almost exclusively in handheld mode.— Shane Satterfield (@Dinfire) February 23, 2017
Nintendo already announced a day one update that will hopefully address this issue, although this issue wasn’t specifically mentioned for the update. However, with how many reports are coming in, and considering the limited number of Switch’s out in the wild at the moment, it’s something to keep in mind as launch day approaches.
We have reached out to Nintendo for comment, in order to see if this was a known issue and if it is, if it will be addressed in the day one patch. We’ll update this story should we receive a comment.
