I have 2 spare analogs. I replaced and tried both. They also exhibit the same issue. It is hard to believe that the analog I replaced 3 months ago started having issue. Now 2 more as soon as I installed them have the same issue. Are they all faulty or could this be another joy con related issue?If you only push up and it register a down along with it, it is moving on it own, you should get replacement analog stick and replace it. I recently had one of my joycon drift, where it move on it own, I end up replacing the analog stick.
