No mobile internet with Android apps

[jsyri]

I’m familiar with the problem with switching connections from my previous Xperias, but I think this is different issue. I literally have not been able to get any Android app connect through mobile connection even once on my c2. Even on first boot, when I only had mobile connection configured, Android apps didn’t manage to connect to internet. (Also happens when I’m at home, that is, not roaming)

I tried this. The C2 was configured almost a week ago with WIFI. Android apps worked. Today I insterted my SIM card and tried 3G and 4G networks but none of them is usable for Android apps (no internet). Reboot didn’t help.

In my XA2 there is no problem at all (except sometimes, disabling/enabling mobile network helps here), so this is a bug of the C2 (software).

@joboe

so this is a bug of the C2 (software).

Yes this bug (AAS can only use WLAN connections) is confirmed by Jolla and I’m sure this is high on their list of things to fix for the next release.

Seems my C2 is struggeling with the same problem.
Is this the ultimate, official bug report?
Can we add someting like a vote to indicate our interest/being impacted by the issue?

@hansdej

Seems my C2 is struggeling with the same problem.

Every C2 suffers from this and Jolla has acknowledged this issue in other threads so there isn’t anything else to do than wait for next release and hope they have managed to fix this by then.

I experience this now on my C2, too and I experienced it with my Xperia 10 II. I have an O2 sim card.
The problem is that the appsupport runtime cannot find a matching APN descriptor and reports that internet connection is not available although it is. You can test it by using WhatsApp. This app works because it does not rely on the android internet connection signalling mechanism. It just tries to send.

I fixed it on my 10II be editing the file /system/etc/apns-conf.xml. I added the following APN description for my sim card type

  <apn carrier="O2 DE Internet"
      mcc="262"
      mnc="07"
      apn="internet"
      mmsc="http://10.81.0.7:8002"
      mmsproxy="82.113.100.5"
      mmsport="8080"
      type="default,supl,mms"
  />

This fixed the problem on saifishos 4.x. With sailfishos 5.x the file does not exist anymore at the location or it is read from a different location. A matching file I found at /opt/appsupport/rootfs/system/etc/apns-conf.xml but it is read-only.
@pvuorela is this the moved file? How can I edit it? Where can I contribute my APN configuration?

The values for the configuration I obtained by inserting my sim into an android phone and using the app AIDA64.

Can you please reread known issues in Release notes before posting?

[himmi]

I don’t understand your posting here … The dude has an workaround for a problem mentioned in the ‘known issues’ and he just ask what happened to the file and where to put his config in … imho he just want to help and advising him to the known issues is not cool, because in the known issues is his workaround not mentioned …

[filip.k]

I understand your understanding of this. But C2 doesn’t have the same VoLTE config. Maybe even none if there are no VoLTE packages. That’s written in the Release Notes. We all hope that’ll change soon.

@ hschmitt: I do appreciate your findings!

If I’m wrong (which I hope I am) I’m sorry for snarky comment.

[himmi]

So when I get it niw right, the C2 has a complete other mobile network stack as the prior SFOs versions?

[filip.k]

I’m not an expert but from what I read here is that VoLTE part is very different. So they might changed other parts (even config) as well.

[hschmitt]

I read it, but I wanted to share my findings. And I guess I could fix it if I knew the files - and by the way it is not about VoLTE. VoLTE is the phoning part.

[filip.k]

Oh, so I was just smartassing then as himmi let me know (thx for that btw). Harry, I’m really sorry!
Note to myself: I should not reply in the bad mood.

With your knowledge you should be in C2 VoLTE testing group.

[avhakola]

I think this answers your question:

@Jolla

As of now, we are maturing software specific for the C2 hardware and the factory process. In particular, there is a mandatory architectural change in the telephony stack and software adaptation required to support the specific C2 modem configuration thru Android HAL. The C2 will be using a new version of telephony binder interface that got introduced in Android 13. While the C2 will be the very first Sailfish device that uses the new interface, it will be eventually used in other future Sailfish devices as well. This is a major re-implementation that has kept us busy since the beginning of the whole project.

@hschmitt

Where can I contribute my APN configuration?

C2 does not support mobile data in AppSupport yet. Therefore, you cannot fix it.

[MRQ]

Wifi is also not working with Andoid apps after wifi-network change. I have to disable>enable Wifi and then stop>start AppSupport.

[hschmitt]

Actually mobile data works e.g. WhatsApp works without a problem. It is just that AppSupport does not find a matching APN and therefore signals “No mobile data connection”. I thought there is a github repo to contribute. I found https://github.com/sailfishos-mirror/mobile-broadband-provider-info, but that is for the sailfishos part I guess.

[attah]

I find it highly unlikely that AAS has to “find its own APN config”.
You should trust @jovirkku or provide reasoning - now you did neither and it’s just noise.

[jsyri]

For me, all the ‘please be quiet, this can’t work’ feel much more like noise than people sharing actual technical details of the problem

[attah]

I’m asking them to prove it is not just technical mumbo-jumbo; because it sure sounds a lot like it.
