Hi,

Since a week I have Jolla C2. Does anyone know why GPS is ot alwasy working?

Once it works it seems to be very stable. I test it with two android apps: Sygic and Locus Maps.

But on regular basis the GPS doesn notwork a all.

Any suggestions are welcome, because use GPS very often for hiking and traveling.

Kr,
Hans

Does it really not work at all or does it just take a very long time to get a fix? It might take several minutes, depending on the signal quality.

You might want to install GitHub - direc85/harbour-gpsinfo from OpenRepos. This app should show how long it takes to get a GPS fix and how many satellites are visible.

Thank you for your suggestions. I just tried it and you may be rigth. It Can take a while before the GPS detects the signal and satelites.

I will try more during the next days and give an update on my findings.

Regards, Hans

The problem with GPS on my Jolla C2 becomes more clear now.

  1. It seems that the GPS does not work when I am in a building
  2. From outside the GPS works well, although sometimes it needs a few minutes to find the satelites.

I wonder if this issue ismonoy related to my device or if it is a general weakeness of the Jolla C2?

This applies to all GPS devices, not just the Jolla C2. Other phones might use some “tricks” to show a location faster, such as estimating it based on cell tower positions.

There is also A-GPS which should reduce the time needed to get a GPS fix by downloading information via mobile data. It is possible that the A-GPS implementation on the C2 is broken.

For me the GPS is very poor on the C2 as well. I’ve tried navigating with it between France and the Netherlands this year, not a pleasant experience; two issues really:

  1. Oftentimes it simply doesn’t get fix, sometimes fixes itself after a reboot, sometimes requires a 2nd of 3rd reboot; then works
  2. While navigating it usually works fine for a period, either minutes to hours, but then the fix quality gets so poor that the navigation goes to the other side of the highway, or even a nearby village, usually requiring step 1 all over again

This happens both under native (Puremaps) as well as Sygic on Android; however Sygic is special since (on top of Android) it runs so slow that new challenges start to arise, especially in conjunction with points 1 & 2
