When using the Joy-Con controllers wirelessly, characters seem to move on their own or do not respond correctly.
When used wirelessly, the Joy-Con controllers respond intermittently.
The Joy-Con controller appears to lose connection with the console.
You can tell that a controller's button mapping has been changed because throughout different menus, a spanner icon will be displayed beside the controller in-use at the bottom-left corner of the touch screen.
What to Do:
Try these steps:
Ensure your console has the latest system version.
Ensure the Joy-Con controllers are charged.
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 (1-1.5 metres) of another wireless device, such as a wireless speaker or a wireless access point.
If the issue occurs while a Bluetooth audio device is connected, disconnect the Bluetooth audio device.
No more than two wireless controllers can be connected while a Bluetooth audio device is connected.
Check for possible sources of interference and turn them off. Interference can be caused by devices, such as:
Laptops, tablets, etc.
USB 3.0-compatible devices such as hard drives, thumb drives, LAN adapters, etc.
In most cases it will be enough to move these devices three to four feet (1-1.5 metres) away from the Nintendo Switch console and/or Joy-Con controllers. However, if you continue to experience this issue, please turn these devices off while using the Nintendo Switch console.
