Mobile data is still broken for some Android apps on XA2, even in Sailfish 3.1.0. Several prior releases provided some improvements but it's still not completely fixed. It worries me that its no longer listed in the open issues section in the release notes of Sailfish 3.1.0. Is this bug still worked on? Since it's a "reflash back to Android" kind of issue for me. So please, Jolla, can you confirm that this is still considered an issue and worked on?

Since the error pattern is really fuzzy, let's track it down together.

If you can confirm that a certain Android app does not work on XA2 (with Sailfish >= 3.1.0) over mobile data (but works on Wifi) please list the app below (or upvote if it's already listed). If the same app works for you over mobile data please write a comment and briefly describe your setting.

But let's stay focused on this specific bug (since it's hard enough to track down anyway), please do not list other kinds of connectivity issues. Also let's limit this list to apps that do not work for some (or all) people, do not list apps that generally work.

Edit: It really seems to depend on the mobile provider. Especially o2 Germany (but also some others) are affected. @Jolla, do you have any more insights about this? What's special about o2? And why is the Android subsystem affected by some provider details anyway? I would expect that connectivity (in general) is handled by Sailfish, not Android.

Edit:I found a permanent workaround: https://together.jolla.com/question/209532/track-down-mobile-data-issue-android-xa2-310/?answer=212609#post-id-212609

Hi, I have a XA2 single sim and O2 Germany postpaid contract. if jolla wants to contact me, I am willing to spend time to help them debug it.

Hi,

I would like to hear, that this issue is important for Jolla and they are still working on this... SFOS is great but banking relies on android, so it is still crucial feature.

SOLVED

I got internet connection for all android apps on mobile data connection that did not work before, e.g. Here Maps or Telegram. The problem is indeed with the List of APNs. I have a XA2 single sim and O2 Germany postpaid contract.

What I did

1) Debug your android runtime while you are connected to a wlan

devel-su lxc-attach -n aliendalvik -- /system/bin/logcat -b radio

2) Disable the wlan and find a line like this in your logs

12:44:53.253 276 276 D DCT : [0]buildWaitingApns: usePreferred=true canSetPreferApn=false mPreferredApn=null operator=26207 radioTech=14 IccRecords r=SimRecords: mDestroyed=false mContext=com.android.phone.PhoneGlobals@6f176a2 mCi=com.android.internal.telephony.RIL@9582fd0 mFh=Handler (com.android.internal.telephony.uicc.UsimFileHandler) {a410f33} mParentApp=com.android.internal.telephony.uicc.UiccCardApplication@4c732f0 recordsLoadedRegistrants=android.os.RegistrantList@ff60069 mImsiReadyRegistrants=android.os.RegistrantList@a145aee mRecordsEventsRegistrants=android.os.RegistrantList@736b8f mNewSmsRegistrants=android.os.RegistrantList@b848e1c mNetworkSelectionModeAutomaticRegistrants=android.os.RegistrantList@653a25 recordsToLoad=0 adnCache=Handler (com.android.internal.telephony.uicc.AdnRecordCache) {6f37fa} recordsRequested=true iccid=894806105[****] msisdnTag= voiceMailNum=null voiceMailTag=null voiceMailNum=null newVoiceMailTag=null isVoiceMailFixed=false mImsi=260060[****] mncLength=2 mailboxIndex=0 spn=null mVmConfigcom.android.internal.telephony.uicc.VoiceMailConstants@7c531ab mSpnOverride=com.android.internal.telephony.uicc.SpnOverride@95a7008 callForwardingEnabled=0 spnState=IDLE mCphsInfo=null mCspPlmnEnabled=true efMWIS=[B@a194a7c efCPHS_MWI=null mEfCff=null mEfCfis=[B@95eaf05 getOperatorNumeric=26207

Important is the value after "getOperatorNumeric=" for me this is 26207

3) Download the xml file from https://android.googlesource.com/device/sample/+/master/etc/apns-full-conf.xml

4) Search for apn entries where the attribute @mmc is equal to the first three digits and the attribute @mnc is equal to the last 2 digits. The XPath to select the nodes is

/*/apn[@mcc = '262'][@mnc = '07']

5) Find the entry that is the correct for your provider. For me it was

<apn carrier="o2 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"
  mvno_match_data="2620739"
  mvno_type="imsi"
/>

6) Tweak the entry till it works. I changed it to

<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"
/>

I removed the @mvno_match_data and the @mvno_type attributes and changed the @carrier attribute a bit. I don't know which change did it, but the configuration now works for me. - Itseems that changing the carrier attribute has no affect.

7) Backup the file /system/etc/apns-conf.xml on your phone.

8) Rename the file to "apns-conf.xml" transfer it to your phone and replace the file called /system/etc/apns-conf.xml

devel-su
cp apns-conf.xml /system/etc/apns-conf.xml
chown root:root /system/etc/apns-conf.xml

9) restart the phone and disable wlan

this sounds very promising. i have o2/drillisch...will try that in the next days. hope others will too and report.

This worked for me! Thank you very much!

I didn't replace the file, though, just made a backup copy of /system/etc/apns-conf.xml and edited the carrier attribute and removed the mvno_match_data and mvno_type attributes in the original file.

I wish I hadn't bought a D1 sim card just yesterday noon... :D

As Karin wrote, this indeed works for o2/Drillisch. Thank you very much for the effort. :-) Let's hope this fix is actually stable in daily use.

Great work! I will try it as well later this evening, but I'll assume it'll work for me. I just was curious to see which setting actually has the gamechanging effect here and while researching the net about the mentioned attributes, I stumbled on the follwowing android documentation: https://developer.android.com/reference/android/provider/Telephony.Carriers where it is stated that those attributes are deprecated. Could this have something to do with it? Still this would sound like a generic problem and not only applicable for some providers. Unless those attributs including their names are exchanged/checked regarding some validity by the provider. But I'm not a mobile dev, so I might be wrong badly. Still it is needed to find out why it works like that in order to verify it regarding a permanent solution...

majuss ( 2019-08-29 18:38:23 +0300 )edit

It doesn't work for me because my logcat prints "22208" as operator code but it isn't available in the apns-full-conf.xml file . I'm using Fastweb sim operator in Italy.

For me, everything used to work fine but suddenly most apps (including microg) cant connect any more. This is extremly weired since it used to work in tje beginning (including DB navigator) and I really didn't change anything.

Works on Wifi but not on mobile data (Sailfish 3.1.0). XA2 dual sim (only one SIM installed). Provider Drillisch / o2 Germany.

The app always says "No Internet connection" and does not even try to connect.

So we have a quite minimal reproduceable testcase with a working setup and a non working setup. This should be a very helpful input to Jolla for isolating and fixing this bug. If they are even still working on it. What is the different between o2 and Vodafone that confuses the Android subsytem?

@pemek, can you convert this to an answer, so it can be separately commented? What is you setting, o2 Germany, as well?

I have an Xperia XA2 Plus dual SIM. The first SIM (o2 Germany) has issues. The second SIM (Telekom Germany) works fine. o2 Germany seems to be problematic for many users.

Hi, thanks for getting involved. Which settings shall we try? And where; Sailfish settings or Android settings? Note that mobile data works fine in Sailfish (native apps). Mobile data also works for some Android apps, but not for all. Interesting observations: In Android settings "Network & Internet" > The field "Mobile Network" (or similar, translated from German) shows the name of the provider "maXXim" (virtual provider in the o2 network), but clicking on it goes back to overall settings (as if I clicked the back button). If I open SIM card settings, it shows provider: "Unknown", mobile number: "Unknown". Clicking on "Mobile Plan" is shows "maXXim has no known source website".

Mario ( 2019-08-01 22:15:38 +0300 )edit

Interesting: I don't have that maXXim stuff, its showing 'o2 - de+'. Where do you find the SIM card setting within the android settings? When I tap on the 'mobile plan' section, there is the following message: "Please connect to the internet". This is consistent in the end, that even the settings app of android can't detect an internet connection. However, the questions @Mario asked (which settings should be checked, and applied exactly where?), are still the same.

majuss ( 2019-08-02 17:13:20 +0300 )edit

I also switched some settings today: The data access point (sailfish settings -> mobile internet -> data access point) can be set between Ip (v4, I guess), Ipv6 and dual mode. Restarted android support after every change, but still the same issue regerding the relevant apps (checked with here maps and komoot). So from gui, I don't think we can do much more, can we? Any suggestions, what possibly can be done via some cli actions in that case? I still have the impression, that we all (including jolla) can describe the problem, but nothing is known about its root cause so far. It's slighty isolated by the provider dependency, but thats all. Why O2 germany (and partially vodafone?) and not any other operator, nobody can tell. How can we learn more about this?

Fasten your seatbelts.... I think I solved this issue, and the answer was always there: https://together.jolla.com/question/200333/mobile-data-doesnt-work-after-updating-to-30114-on-xperia-xa2/?answer=200508#post-id-200508

(Very well hidden in tjc and with just 2 upvotes)

I put a (even inactive) sim (klarmobil/D2) in the secondary slot, and I could then disable the first (O2) sim. Once I reactivated it - baaam - data connectivity was restored for android apps. I guess this bug is probably related to some internal routing, maybe even on the hardware base since the inability to route data through sim 1 withstands factory settings once appearing. I also guess this issue is NOT network dependend and the quite high number of German O2 customers is just pure statistics - O2 is simply the largest German provider, and Jolla has a quite large German user community. Hope that helps...

With respect to network dependency I can say that I have Vodafone.de as SIM1 and congstar as SIM2 and don't see those mobile data issues. So I would suggest it is somehow related to O2

Activating flight mode and reenabling Mobile networks again triggers the no connectivity bug on my phone again. It can then again be repaired by switching sim cards as described above. So my solution is rather a workaround until this is fixed by Jolla and it won't help single sim phone users, but hopefully it helps for tracking down the issue.

@jollalo I was using my phone for quite some time until this problem appeared for me and even disappeared briefly again. Can't say if it's coincidence. However, what I CAN say is that switching sims helps for me. My second sim is klarmobil/D1 (but inactive). Maybe it would help to test if switching between two O2 simcards would also "repair" data connectivity. I currently don't have a second O2 simcard at hand, though. Maybe someone else could try to test this or even reproduce my method to restore data connectivity on O2.

Well known to me (same device, same conditions, O2).

I replaced the SIM for testing purposes with Vodafone SIM. Mobile data was there right now for ALL Apps. O2 seems not a good choice for the XA2.

It is reproducible.

Edit: o2 Germany + Vodafone Germany

it is so unbeliveable, that the combination of XA2, some random Android apps and a German provider results in no connectivity. I think there are other providers in europe with the same problem. maybe we should open a thread with listing the bad providers across europe??
