Venu 2 keeps turning off

My 2 year old Venu2S keeps turning off part way through walking activity. Today at 65% charge it saved part of the walk while I was still walking and then turned itself off. The only way to get it to turn back on was to put it back on the charger. It becomes almost a daily occurrence now. Can you please advise in how to fix it? 

  • I spoke with Garmin support today and the agent I spoke with said there will be no more firmware updates for this watch. He also said it's not possible to roll back to an earlier firmware version. He offered to do an exchange for a refurbished model for $140, but I don't think so...
