My Versa was fully charged yesterday before wearing, but by mid-afternoon I noticed the screen would not respond and when I took the watch off, the green heart rate lights were off and look as though they have some condensation in them. The app is unable to locate the device. I've checked carefully and cannot see any cracks or even scratches on the screen or casing. I have worn this for about 2 years without any complaints or issues, in fact, I proclaim the awesomeness of it to everyone who asks, so to have it suddenly die has me scratching my head a bit. Any thoughts on what happened or what I should do?
