Title: Altitude big steps in track recording
Post by: davidsiroky on September 05, 2023, 22:28:50

Hi,

I'm using Locus Map 4 and when I record a track I can see steps/plateaus in the altitude. Looks like the GPS is waking up only sometimes but latitudes and longitudes are recorded fine.

I didn't have this issue with Locus Map Classic.

How can I fix that?

Hello David,
really interesting. May you please compare the setup of the "Altitude manager (https://docs.locusmap.app/doku.php?id=manual:user_guide:tools:altitude)" screen in both app versions?

These settings are identical in both apps.

For comparison this is the same track recorded with Locus Map Classic

Thanks for the screenshots.
What about recorded tracks? Is the track in Locus Map 4 without gaps and straight lines? If there are any problems, please check that the app has "background location access" permission.

The track itself is fine: 2023-09-01_Krkavec.gpx
(Locus Classic: 2023-09-08_Krkavec.gpx)

The permission is set to "Allow all the time".

Any idea how to fix it?

Hello David,
sorry for the delay in the answer. I do not know what exactly may be the reason anyway suggest checking battery optimization on your device: https://docs.locusmap.app/doku.php?id=manual:faq:gps_lost_fix_android6 . This usually cause a similar issues in the recordings.

Battery optimizations are off and GPS permissions are "allowed all the time".

Maybe if you send me some debug apk then I can give it a try.

Hello David,
it has been some time. Sorry, I forget to answer here.

Is there still interest in fixing this issue, if you still have it?

Hi locus Team,
I'm switching to the new version and doing my first hikes. I have exactly the same issue as David reports, I suspect that is due to this version as I never had this issue before.

Any new insights?
Best regards
Joop

Hello joop,

nothing new, sorry. A few users in recent months wrote to us about some problems with GPS. Usually, it was fixed by an Android update or by toggling to the second option of the app settings > GPS & sensors > "Google Services assisted location". Give it a try as well.

Hi Mention,
Thanks for the reply, google services assisted locaton is already on. I changed the filter to medium, but that did not solve the issue. Use of offline altitude data seems the help, but that should not be necessary I'd say
