Am i only one? Stratos bad GPS. - Amazfit

Hello,
I recently purchase Amafit Stratos main for sports activity and good GPS tracking.
My decision was made according many good reviews but what a surprise?
After several activities i was very very disappointed by its GPS tracking, im on latest 2.3.7.0. ROM.
For example walking only 6km, it was off by 200m.
The gps map was showing gps drift and bad road tracking, i was compare it with polar m200 and garmin fenix 5.
When it upload data with Strava non of data didnt match, i mean total distance and every km i run.
I even make factory reset, but results was the same, bad unprecise gps and different data with strava .
So i search again on net for someone like me complaining about bad gps accuracy for stratos but nothing found!
Please help.

1. If you have 3D Data on, try turning it off (3D data adds elevation to distance, see manual);
2. Try disabling auto-pause and alerts in activity settings;
3. Wait for a while before you hit the GO to start recording an activity to make sure you got a good GPS fix;
4. GPS works better in open spaces, no nearby buildings or trees;
5. Sync often with Amazfit app to make sure A-GPS data on watch is up-to-date;
6. Forget about comparing data with Strava: it smooths data and does its own calculations so it will always be different (if you disable 3D data and use "race mode" on Strava, it's a little better).

Thanks for your help. I will try to correct my settings accordingly your suggestion.
Thanks again.

I have stratos too. And yes, GPS is veeeery bad on this watch. On 5 km walk difference between stratos, samsung gear s2 sport, samsung s8 phone and huawei mate 20 lite is: Stratos: 4,13 km
gear s2 sport: 4,99 km
samsung s8: 4,98
huawei mate 20 lite: 4,97 km
so it is very bad in just 5 km...
Also heart rate is not very good too.

And it is not just one walk. I keep track about this for a while. Calorie counter and steps are about same (20-30 difference), but GPS distance is way off....

200m out? How about around 8 miles out, with the start out in the sea?!!
Apparently I am nearly a world record cyclist too for pace
Too be fair I normally find GPS OK.

And new "great GPS accuracy" today....
8.5 km walk
1.2 km error....

I also have problems with gps. For the first 12 seconds of the run, it does not count the distance.

Latest firmwares for all watches (Pace/Stratos/Verge) introduced "Activity reminders" (also called Sports reminders on Verge) that are supposed to auto-start and auto-stop recording activities, but they have a bug (besides the fact that I don't think they actually work as of now): even if both are disabled by default you must enable and then disable both options in watch Settings -> General or your activity most probably will miss the first initial and final minutes of GPS data. Simply enable both, quit settings then go back and disable them again and it should be fine.

I tried all these solutions many times. I tested return to 2.3.7.0, later to 2.3.8.0, I also checked PACEficator Project | Everest 2.0.55.1 ROM v1.8, still the same, for 12 seconds the watch does not count the distance. This is about 40 meters, of course, depends on the pace of running. Compared to Garmin Fenix 3, Stratos will always give me about 40 meters less.
