I got the same exact massage SIX (!!!) times between 8:49pm and 9:23 PM. SIM is still non-functional.
Even if i managed to make it work, I am not sure I'll keep it after a full day with it. It counted thousands less steps than my (already slightly undercounting) Gear S, and the step count is not the same between apps on it.
Gear S: 16065
Urbane: 13182 on watchface, 12538 in Fit app (the second may be Fit's fault, who knows...)
I do need my wearables sim to work no matter what.
I'm having the same exact problem with step counting. I look ridiculous this past week with two (or three watches) on at the same time, but I've been home, and it's been hoodie weather, thankfully.
Here's my Google Fit daily average (rounded) for 6 days:
Gear Live: 7000 (Google Fit)
Gear S2: 5000 (Tizen)
U2LTE: 4500 (Google Fit)
U2LTE: 6500 (LG Health)
I've been fairly confident that my Gear Live is pretty darn accurate the past three months. I've been pretty disappointed that the S2 is undercounting the past 6 weeks.
I've been quite concerned that Google Fit on the U2LTE has been counting even less than my S2 (which I already think is undercounting), while the LG Health watch face has been close to my (accurate) Gear Live.
Just downloaded the new Google Fit app update this morning. Will monitor and report back any findings.
