Hi Sailors,
What is the best SailfishOS device for GPS / Galileo tracking ? Jolla C2 or one of the Sony Xperia 10 II-III-IV family ?
I need fast & stable position tracking for my personal needs, both using Sailfish and Android apps.
Thanks in advance !
You won’t find a reliable answer to this question since no user has a C2 in his/her hands yet
Ok thanks for your answer. What about Sony Xperia 10 II-III-IV, are they good at GPS / Galileo tracking ?
My ex Sony Xperia XA2 Plus was very slow and bad for GPS tracking…
Sorry, I can only tell that my very old XA2 Ultra performs really bad in this respect
Xperia 10 plus has no GPS tracking available unfortunately.
Why use phone for that and not dedicated tracker?
Because this way I don’t need an additional device 
Also, having a good navigation app on my Smartphone for me is a must.
But like, tracker you usually mount in something you want to track and you track it 24/7, i think mounting phone 24/7 won’t work that well and its gonna be fire hazard
My Xperia 10 performed great.
Keep GPS on all time and it works fine with most devices I assume. If you shut it down, it is going to take a long time to reconnect.
Android devices never shut GPS down, even if you deactivate it in the action menu but only limit access for apps with the button. (meaning internal processes to track you are still active).
Like that they are fast to reconnect, but your data protection suffers a lot.
I think since SFOS seems to shut it down fully, there is no device that will be very fast in these aspects running SFOS.
Anyway, with MLS and PureMaps and OSM Scout server for offline usage I find navigation to be pretty nice on my Xperia 10 III. But again, I assume it is not really a hardware thing but a software thing.
Best regards

The same for me. GPS does not work on the XA2 plus. It did work on the 10 III but slowly. I use MagicEarth because it has not trackers and it is reliable. I use it offline on my old ipad mini cellular . I adjusted garden thread on the ventilator of our Prius. Thereon the ipadmini with cover hangs. Hopefully Jolla C2 has a functioning GPS, like Jolla 1 had with Here Maps.
I don’t think so. Read above your comment.
X10 III GPS under SF has very poor lock acquire compared to Android.
The issue is that it takes a long time for the phone to get lock, even when it has many strong GPS signals.
If the GPS signal is weak-ish, for example under foliage, the phone cannot get lock at all, not matter how long it is given.
Under identical conditions, side by side, an Android X10III gets lock in a few seconds.
This is not anything to do with MLS or assist of the GPS.
This appears to be exactly the same problem the XA2 suffered, but on the XA2 the gps itself seemed to be weaker, and so it was often unable to lock out in the open.
I would expect that the later Sony’s will probably have the same issue, as it seems likely that the Sony AOSP has some GPS difference compared to Android, from long ago.
If Sony GPS performance matters, stick to Android.
When I go hiking I have to take my Android 10III as the SF gps does not work in the bush. (also the flightmode standby battery drain flattens it in a few days)
The C2 probably has a better chance of working properly - as I said, my thought is that this is a Sony AOSP fault, not a Sailfish issue. I had a phone with a Mediatek chipset a while ago, and the GPS performance in dense wet bush was absolutely fantastic.
