Lapnotifications on phone during activities.

Hello, 

I've set autolaps during several activities:

Every 1 km for walking and running, every 5 km during biking. Works fine....but...

When I carry my phone with me during an activity my phone is reading loudly my laptime.

Why?? How can I turn this feature off?

Of course I can mute my phone, but every time I forget to Unmute it after my activity. I just don't want my phone to tell me what my laptime is. I have my watch for that.

Does anyone know how to change is weird feature?

Thnx

Chris
