6 days into wearing a new Vivoactive 5, the screen cracked. The crack goes all the way across the face, side to side. At first it looked like a scratch, within an hour it went through the glass. Garmin won't replace it because they say I must have bumped it. I have no recollection of hitting or dropping it. How long will it work with the crack as long as I don’t take it swimming? Is this a common problem with Vivoactive 5?
