My heart rate wrist sensor suddenly stop working or turns off by itself and then turns on and stays on 72 wich I know it is not my heart rate, i read that this it is happening to a lot of people and garmin does not fix it.
it only happen in running, I try in road cycling and swimming and does not happen, it was not that I wear it loose or wrong because I check that.
P.S. sorry about my english,
