I've been having problems with my 4th Index left controller. Since I received it the ring finger stops tracking randomly, reporting it as still being pressed with an open hand. I've tried the calibration thing while turning it on but doesn't do anything. Obviously, not being able to open hand is bullshit for most games. Are there reports of broken capacitive sensors? Time to RMA again?
Pic related is how test controller looks with an open hand. Notice how there is still Grip and Pull.
