Watch Active 2 - GPS and Calorie count inaccurate

[wooky2000]

It seems like this is happening with all GWA2s so not specific to my unit. I've been using the Gear Sport for the past 2 years and have been religiously running, so I have a good benchmark.

Picked up GWA2 on 9/27. Had 2 runs with it so far - I've done both courses multiple times with the Gear Sport.

Run 1: Neighborhood loop (4.85 miles) - distance is accurate so I thought GPS was working. However burned calories was 370 calories. There is no way a 165 lbs male running 5 miles at a speed of 7 min/mile burns only that much.

Run 2: Running Track (3.5 miles / 14 laps) - if you look at the post-run map, it is clear that the watch is all over the place with the GPS coordinates. With the Gear Sport, it outlined the track oval quite well. With GWA2, it almost felt like the "high GPS accuracy" setting was not even functional. Also calorie count came in at 307 calories. Gear Sport used to report 475 calories which is much more in line with the treadmill. 

Also, this exact issue seems to have other journalists noting it as well:

Come on Samsung... the product is called Watch Active 2. It is supposedly made for fitness/health tracking. That is the one thing you cannot get wrong. And you had it near perfected with the Gear Sport... can this be fixed with a software update?

I have had the same problem with my Watch Active 2. The watch does not measure distances reliably during Walking workouts.  I track I regularly walk is 3.21 km measured using Google Earth. One day my watch will measure the distance correctly (3.21km) and the next day it will measure the same walk as 2.6km. That is a significant discrepancy. For a watch that is advertised as a fitness watch this is totally unacceptable. If there is no fix scheduled soon I will advise people not to buy this device.

I have a similar problem with my new Active 2. Although I don't have anything to compare it to. However, I decided to go to the track and test the GPS accuracy. I did 10 x 800m and it was all over the place, between 820m up to 970m; always high!

These were the results:

890m, 930m, 910m, 970m, 820m, 920m, 830m, 950m, 970m & 960m.

 Could be my settings? A software issue that was fixed or any number of things.

I bought it specifically for running and love it's good looks. That said, I do need the accuracy of the GPS and HR monitor (I'm 65).

I am having similar issues as well.  Ride my bike on the same route every trip.  My phone in the beginning was an S9 plus and seemed to have pretty accurate results.  Upgraded to the Note 10 plus with the same accurate results.  Introduced the Avtice 2 to my  aresnel and at first it would produce very similar results to the phone.  However now, I am losing almost 2 miles off of the same ride and route.  This seemed to start a few days ago.  My next ride I am going to try just using my phone to see how that works, but the watch is definitely off by a large margin now and not sure what caused it.
