Hi!
I've had my vivosmart 4 for coming up to a year now - no massive problems with it until now. For the last few of weeks, I am being increasingly frustrated with the activity tracker not being reliable.
For example, yesterday it stopped tracking my PT session about 30 mins into a 60 min workout. And while swimming today I set it to track about 4 or 5 separate times and still came out of the pool with no data recorded. Every couple of lengths it seemed to cancel and go back to the home screen - with no vibration that it had done so.
Any suggestions with how to solve this? I've been looking for a way to lock the screen to avoid any accidental cancellations of tracking - but as I use it as a normal watch too I would still like the gesture raise function to be on.
