It has been really disappointing to see how disinterested the company has been in actually helping customers solve this problem. My watch also started vibrating constantly and switching between various screens until the battery went dead. If you are having this problem, treat it like a cell phone that has been submerged in water. Put the watch in uncooked rice for a few days. You don't need a lot of rice, only enough to cover the watch itself. I took my band off of the watch. I was ready to throw my fitbit away when I remembered that I had washed it under running water the day before it failed. The Charge 2 is supposed to be water resistant. Having read the company's response to this concern, I assumed that the watch was shot. I put it in a ziplock bag with rice and forgot about it for a week. When I pulled it out, I found that it was working perfectly. That has continued for 3 days. It is difficult for me to believe that the company didn't know that this was a moisture issue.
