Hi,
I'm still a VA3 beginner but I think this is a bug and not a user mistake.
Yesterday I was running the first time. After about 3km the watch was suddenly vibrating every 30sec and has shown different things on the display ( e.g. heart rate graph). The display was locked and shouldn't change I would say.
Once I was done with the activity I've pressed the button to unlock and the to stop. Unlock was ok but I couldn't stop the activity. The touch screen was not working at all. After a while I've done a 10-15sec long press to shutdown. After restart I was able to stop the activity and save the result.
At this time I had installed the dwMap app on the VA3 but used the standard running activity.
However I thought that dwMap caused the issue and uninstalled it.
Today I was running again. After 3km the display started to show the big lock icon on the screen. After 10km it started to vibrate for no reason again. I've not set an heart rate alarms etc. At km 13 I tried to stop the activity. Unlock with button was working fine but instead of stopping the activity it was just paused and the touch screen and bezel wasn't working. Long press button to shutdown and restart -> same problem. Long press shutdown/restart again -> now I was able to stop and save the activity.
Temperature was about 4°C and my fingers where really cold.
I've FW 2.60 installed.
