My Joy-Cons need fixing for two reasons. Firstly, it doesn't register button presses for the A, B, Y, X, ZL, and ZR buttons, at random. For example, when I do a Cap Jump in Super Mario Odyssey, the ZR button press won't register. And secondly, the HD rumble is too strong, also at random times. Personally, I don't think it's Joy-Con Drift, because that sounds different than what this is, but if it is Joy-Con Drift, please tell me. Oh, I should also mention that this only occurs when I'm playing in a mode that involves the Joy-Cons being detached from the console, TV and tabletop mode. It doesn't occur in handheld mode.
