I don't have a vivosmart 4, but if it is anything like the vivosmart 3 then you will need to go into your settings on your phone that deals with auto laps and change it to km's. You would think that if you choose your units to be in kilometres then that would change automatically, but no, you will need to change this setting as well. I haven't used my vivosmart 3 for some time so I can't put in each individual step on how to get to that setting.
Vivosmart3 has broken wrist band (design to hold only for 11/2Y ?) but this unit interprets my setting correctly (metric) Also... Vivosmart4 does not take custom setting for stride length. My stride was calibrated and according to GPS, and Vivosmart3 it is around 70 cm long. In Vivosmart4, doesn't matter what I set, it os always 83 cm long ( someone 8 ft tall?) 1200 steps for 1 km.
It is really frustrated to get brand new unit with so many bugs, which should be caught basic QA testing:
1. Lapping in miles
2. Start count walking activity always in 10 min ignoring setting (fixed with v 4.00)
Or maybe they hire programmers from NASA? For Mars lander, they done all calculation in feet but programmed lander in meters. Ops. 20ft under surface. :)
