Love my vivosport, but even with the screen in permanent lock it unlocks itself when I'm swimming or surfing.
ive tried setting it for different activities, but no joy.
within 30 minutes max, the action of water on the touchscreen unlocks it and then normally stops my activity.
i contacted Garmin and they said I'm being too vigorous.
i don't believe the unit is faulty, as it works well everywhere but in water. But as I bought it to swim and surf, I have a very pretty but useless bracelet. any suggestions?
