galaxy watch 4 can only use own gps it can't use phone's gps

[qwefoij]

Hi, my galaxy watch 4 (SM-R860) can only use its own gps when tracking an activity. I have read that it can use the mobile phone's gps, but that's not true, at least for me, but I'm using an asus phone. Obviously using own gps will drain the battery a lot faster.

My question is, does it need a samsung phone to make this work? has anyone tried, either with samsung or non-samsung phone?

No, i can't get spm when i use ghost racer. I've tried everything, but i only have heart rate

About strava, i have noticed similar problems and i think strava does some corrections based on popular routes or whatever

That is not the solution of the problem. Please, read all the replies.

When using apps like Ghost racer, the watch use phone gps. But it's not the case with samsung health app.

Please, check the real problem and try to solve it. The samsung health app is a really good app, but the gps issue needs to be solved

Samsung seem to do very little development on Samsung Health.  The battery usage on Galaxy Watch 4 using GPS is ridiculous, I need to charge mine twice a day.  Surely Samsung can fix this by allowing the watch to us the phones GPS.   Even basics like scanning food bar codes are not available.

I believe that Samsung Health does some corrections on gps data, based perhaps on its internal gps signal accuracy. I linked my health account to strava..and after export, strava calculates a longer distance based on gpx points. so if I run 21km on watch...strava recalculates to 21.8 or so..always a longer distance due to inaccurate gps points. this could be a reason not to use external gps...because its software continuously adjust its own gps route...while using external gps the code must be changed not to adjust anything.
