So, there’s been cases in regards to the Nintendo Switch about how the Joy-Con controllers, specifically the left one, hasn’t been functioning fully at times. Now, while this hasn’t happened to every person (for example, I have had no such issues, neither has Tyler or Will here at Outerhaven), it is a large enough sample size for people to take notice, and thus, Nintendo is working on the problem.
The main issue is that the Joy-Con emits a signal to the console, regardless of mode you are playing in, and sometimes the signal doesn’t connect. While a more permanent solution is being made, here are some things Nintendo suggests you do in the meantime to try and get the problems to get sorted out:
Try to decrease the distance between the Joy-Con and the Nintendo Switch console.
Ensure that the Nintendo Switch console is placed to minimize interference with the Joy-Con. It is best if the Nintendo Switch console is placed out in the open and that it is not:
Behind a TV
Near an aquarium
Placed in or under a metal object
Pressed against a large amount of wires and cords
Within three to four feet of another wireless device, such as a wireless speaker or a wireless access point.
Check for possible sources of interference and turn them off. Interference can be caused by devices, such as:
Cell phones, laptops, tablets, etc.
USB 3.0-compatible devices such as hard drives, thumb drives, LAN adapters, etc
If all else fails, the Pro Controller is out there, and you can use that without fail as it’s a different kind of controller. But hopefully, you won’t have to go that far, and just as hopefully, Nintendo will fix the problems soon so that we can enjoy our Joy-Con’s and Nintendo Switch’s without issue.
