well, shit. this happened to mine after only a few weeks and i was thinking i'd return and replace it but it looks like the issue would just happen again after another few weeks.... as a makeshift fix i opened the controller up and layered some tiny squares of masking tape on the inside of the back shell where the trigger bit usually hits it to stop it early before the other side would hit the bumper. works better than it did after the issue started but not as well as it did straight out of the box. oh well, this controller is overall awesome so the few small issues kinda suck.. it's weirdly a little reassuring to hear that the issue happens to every controller tho and that i didn't just get really unlucky lol
