seems i may have a dead joycon so might be time to try the hori splitpads
not sure what happened but gonna say opening joycons and maybe replacing something inside is not that hard. Just make sure you have the right screwdrivers.
Those screws are not made from nintendium for sure.
Just mentioned because I’m not a technical person and still replaced many drifting sticks. If it’s already not working is way less scary to try to open it.
