not sure what the issue same phone same hardware ( XA2 )
android os ( sony) worked great GPS locking awsome in house any where outside etc.
2022-21
switched to SFOS , GPS only locks outside home + when start driving car 4-5 minutes after i start driving car ( google maps ) - and waze ,
, i switched to android waiting and hoping that it will fix in future
now its march 2023 ,
came back again to SFOS same issues ,
Navigation is intergral part of my travel cannot work without , GPS now a days is a critical most thing
SFOS team Please look into this and kindly fix this on priority ,
Its working fine , so what i did is i just moved near to the window and got the fixe under 60 seconds ( havnt changed any thing ) . so i am pretty happy, My basic test has been passed which was GPS now i can test the rest which would be pretty fine as well e.g. emails , insta , fb , filemanagers , terminal , whatsapp ( another big challenge
due to DB crypt and non google integration )
Hi @miau ,
Thanks for your information and update on the issue. It’s interesting to know that the SUPL request is working with a Let’s Encrypt certificate.
Did you inject the Let’s Encrypt ROOT CA via suplpatcher? If that’s the case and you enabled secure SUPL connection then you should be able to use other vendors SUPL service (the modem wouldn’t reject the connection as the LE ROOT CA is known).
Nope, i didn’t inject any certificate. I only used your suplpatcher, which like you mentioned doesn’t need to patch anything on the 10iii and made the changes above and finally it it is working again.
A few days ago i read the following blog post (in german):
It provides some nice information about the data, which google gets when using “supl.google.com”.
It also mentions the use of “supl.grapheneos.org”, like @miau suggested.
I tested your gps.conf on both of my XA2s. The first try on the first XA2 was with only 2g-mobile-data (provider Aldi Talk) activated and it took too long to get a fix.
After switching to 4g-mobile-data the fix was there after about 40 sec, which is quite fast for my XA2s.
The second try was with the other XA2 with only wifi activated. It did not get a fix after 3 minutes. Switching from wifi to 4g-mobile-data (provider Telekom) did not change anything. It did not get a fix.
From your pictures, I conclude that on your second XA2 it’s not a software configuration problem but a hardware problem of antenna for the reception of GPS signal as stated earlier in this topic.
You can try to put some metallic wire in the headphone port and see if the level of reception is better.
This is standard situation with XA2 Devices, just like motherboard connectors for antena wires.
The good idea is to take it apart and clean it thoroughly. My cases shown, that there is always some improvement
I tested with mine and do not have a fix. But I don’t have fixes since a long time, even the MLS update didn’t helped me, so I might have a bug elsewhere.
Last weekend i took our dogs for a walk in a light forest under a cloudy sky. With 4g activated i did not get a fix within 4-5 minutes, so i cancelled the test.
The next day at the same location under a clear sky i also did not get a fix within 5 minutes. With my Xperia X (no SIM, only device-GPS, cold start) i got a fix within 2 minutes. GPS on XA2 stays at least unreliable if not unusable. Even with the adaptation of supl.grapheneos.org.
Another problem on XA2 is, if it got a fix, the gps-signal is not “continuous” but “choppy”. In Puremaps the position-mark is stuttering and the map is rotating constantly, because XA2 is often not clear in witch direction it is moving.
XA2 seems to always forget any information of satellites after some period of time. It seems to always start with the use of 0/x satellites in GPS-Info. While the Xperia X starts with e. g. 4/x satellites.
I never had those problems with XA2 in the beginning. I could use it reliably even in thick forests. All problems startet with some update or with the deactivation of Mozilla Location Service. I don´t know.
Same conditions but different situation here. With a Xperia 10ii the GPSInfo tracks 7 satellites but no one is locked (0/7) and thus it do not get the position. The GPS was working pretty well using Android 12 but after the switch to Sailfish, I am not able to receive my position.
* The new location stack does not support UnifiedNlp modules anymore. This was a step necessary to take to get locations properly working on latest Android versions. This means that some features previously available through UnifiedNlp modules do no longer exist. The goal is to merge the most important of those features into GmsCore. For now, the new locations stack is relying exclusively on Mozilla Location Service for network based location.
In settings I set location mode to high precision. And of course, I restarted my device a few times.
Anyway GPS fix isn’t quicker than berfore.
The only thing I could think which isn’t correct is, that I think I have installed Sailfish on my Xperia 10 II with Android 11 preinstalled. So maybe i should have used the option.
–aosp 11
If so, can I just run suplpatcher again with this option?
The output was, that patching was succesful. I tried it just with WLan disabled. so this shouldn’t be the problem. So I try to run suplpatcher again with flag --aosp 11.
I will report…
