My watch started to show noticeable signs of corrosion on two of the pins. After the update, the pins not only stopped getting worse, but over the past month or so, the corrosion material must have wiped away because now I can't even tell where the corrosion was. So at least for me, the firmware update worked!
OP, did you apply the update? If not, definitely close the google plus page.
