I joined this to ask a question I can't find anywhere and not sure how to word it. I have a eleaf ijust 3 and have had it for a few months now, never had an issue but now having a minor issue that could later make it a unusable. I just ran into the issue that my fire button works but only when applying a small amount of pressure that wouldn't be needed for it to work. It only started a day ago and was wondering if there was a way to fix it and an explanation for it. I was thinking it was gunk or something like that build up behind the button but I'm not sure.
