Retuned my Galaxy Watch today for a full refund. I decided to buy a new Gear Sport and have compared it to the Galaxy Watch 42mm over the the last 2 days using identical settings. The Gear Sport came pre loaded with Tizen 220.127.116.11 and records steps around the house just like my GearFit2 which i've always found very good. In simple terms miles better than the Galaxy Watch. On a 3 mile walk the step counts on both watches was very similar, the Gear Sport recording a 1% higher total. Battery usage over the 2 days almost identical as well. I've no intention of upgrading to Tizen 18.104.22.168 and i'm delighted with the Gear Sport's step tracking. I also prefer the slightly thicker wrist band that comes with the Gear Sport, makes the Galaxy watch band feel a little thin. Will be interesting to see if Samsung solve the problem of not counting steps with Galaxy Watch's, for me, i'm very happy with an older model which works as it should.
Sorry, i can't help you much, i've never bothered checking the calories burned and my heart rate reading is very low at the best of times due to eptopic beats not being recorded. As of today the step count is 15817, which includes 2 walks of just over 3 miles and pottering arond the house. Calories burned total is 1839, i wouldn't know whether that is good or bad. BTW, i'm 72 and not into keeping fit in a big way, i just like to do a minimum of walking 3 miles every day.
Good for you, that's a great step count a calorie burn compared to mine, I've done 5 miles with 8000 steps and 1350 calories.. Quite a difference.
Thanks for feedback, interesting to know Tizen 3 works ok with Health V6
klythawk - I must be one of the few that like V6 layout, not entirely convinced its playing nicely with Tizen 4 though which could be the cause of all the problems. UA works great with Tizen, time will tell I suppose.
