I picked up a Nintendo Switch on launch and so far am loving it but I've found a potential issue that I wanted to write about. It's in relation to the Joy-Con controllers, which work fine when plugged into the Switch but have started to disfunction when using disconnected from it.
The problem I've experienced is the left stick either moves on it's own I.e. In Zelda link will run on his own or worse stop working completely.
After trying two different Joy-Con sets and having the same issue I've reached out to Nintendo for help but in the meantime found a workaround that seems to do the trick.
On the Switch, head over to SYSTEM SETTINGS then CONTROLLERS AND SENSORS then CALIBRATE CONTROL STICKS.
Follow the on-screen instructions and once setup you should be back up and running.
