Fix your left Joy-Con connectivity issues and void your warranty in one fell swoop
The Switch has only been out for a couple of days, but the left Joy-Con controller on the new console is already infamous for random connectivity issues. And while Nintendo has recommended a fix that users try and avoid having obstacles between the controller and the console, others have opted to just crack open the Joy-Con and break out some soldering gear to find a more permanent fix.
The Spawn Wave YouTube channel is among those that have tried. By comparing the innards of the two controllers, Spawn Wave came to the conclusion that while the right Joy-Con has a separate antenna board, the left Joy-Con’s antenna is built directly into the main circuit board, where it gets obstructed by a large metal box.
The solution? Spawn Wave...
