Connectivity problem XA2 (H4113) - Sailfish 3.0.1.11

I have also XA2 and WiFi (2.4 and 5 Ghz) and 4G works ok with both OS versions.

Have you tried to reset networking under Settings -> Utilities -> Restart networking... [Restart] button?

I have of course tried to restart network, reboot and so on, but the problem persist. But I have noticed that the time it takes to connect to a mobile network and the level of stability changes slightly depending on my physical location. So I’m thinking that maybe the problem is bigger when the mobile network is using some frequencies and less at other frequencies. In the area where I live, and the problem is worse the providers UMTS frequencies are: 900MHz and 2100MHz and the LTE frequencies are: 1800MHz and 2600MHz.

Connectivity is now much better in 3.0.1.14 but I also still have problems with 4G. The only solution that worked for me is to set the phone to "prefer 3G” and use 3G instead of 4G, which for HereWeGo should be OK. Hopefully Jolla manages to fix this issue for the next release.

I habe next app, who need internet: Kate mobile - work. HereWeGo - doesn't. 2gis (russian maps app) - doesn't. Yandex.transport (russian online pubic transport viewer) - work. BashReader - works, but write - no internet connection.

And Google play - doesn't work all. I install it from android store, and it doesn't opened. Android store - doesnt work without Wi-fi too.

No, don't help change "3G instead of 4G". HereWeGo doesn't work - say: need connection. Weird - why half apps used phone internet, and half can't.

I tryed change SIM slot from 2 to 1, reboot, restart Mobile Data - nothing... And I observe something: when I run android app, which doesn't see Mobile Data and at once minimize app - I see - I have no Mobile Data connection and sim-slot checked as empty. And then slot checked as active and Mobile Data revert. If don't maximize apps - all good, if maximize - already no connection... Weird..... Why? And why all good, if I try open messengers or different versions of an Opera? How I can make log - what happened with internet connection while I try run different apps? I have Experia XA2 Ultra (h4213).

Thanks for the suggestion, but both sim cards are clean and as mentioned sim’s are working just fine in my three other sailfish powered phones.

I also have a XA2 Plus H4493, just flashed v3.3.0.16, no WiFi. It sees the networks but " Sorry. Could not connect to selected network." Both with SW_binaries_for_Xperia_Android_8.1.6.4_r1_v17_nile.img and v16.

The internet settings are exactly the same in my XA2 as in my Xperia X, and in the X everything works fine.

As previously mentioned I have again sent the ofono-log files to Jolla and I hope someone will have a close look and find details of what is going on from the logs.

I hope Jolla will check this before next release because right now my XA2 is just lying idle and I have to continue enjoying the use of Sailfish only using my Xperia X.

It would be very nice if Jolla at least would comment on this issue so we would know if they think there is a problem and they are working on it – initially I thought it might be my phone but learning that others have similar problems with the XA2 it would be nice to hear from Jolla...

Connection is more stable after update 3.0.1.14. Before the update 3.0.1.14 also turning the phone on just with mobile data and wifi off helped. After the phone found the mobile data it was ok to turn wifi on also. But overall its better after the update.

@Cannond As described in my own reply to the question (please see above) everything is also working fine in my XA2 after the 3.0.1.14 update.

I was testing the XA2 very thoroughly using Android before flashing Sailfish onto it using my normal sim card and everything was working fine.

I do not own an Android phone to test and I really do not want to try to reinstall Android on the XA2 to do the same test again. And as mentioned my other Sailfish phones work fine with the same sim in the same location.

I could try to re-flash Sailfish, but it was flashed without errors and everything else works fine, and since others are experiencing similar problems, I doubt this would have any effect.

I really hope Jolla would comment either by saying they don’t think there is a problem with the XA2’s mobile connectivity, or saying they are looking into it and will come back with an answer...

I woukd still suggest you flash android on it. Then if works back to sailfish. I was having issues with the speaker and after testing on android a check worked there and flash sailfish again .... Worked

OK - if Jolla really will not comment on this issue and review the connection logs twice sent to them, I will consider trying, since you had that experience with your XA2. As mentioned I did everything they recommend. Using the phone and testing everything before flashing.

I have now tried to flash Android back on my XA2 and have extensively tested the phone with Android running my normal sim-card for 36 hours.

Using Android the phone connects right away to the provider network and is working on both 3G and 4G connections. I have however noticed that the connection is not as strong as it is on my Xperia X. I therefore think the antenna or the mobile communication module in the XA2 is not as good as in the X, especially when the network is using high frequencies.

After re-flashing the XA2 with Sailfish again (now flashing 3.0.1.11) It seems the phone is connecting quicker to the provider network and also seems to have a slightly more stable connection on 3G than before, when 3G is preferred, but is still disconnecting all the time on 4G at 1800MHz and 2600MHz.

After a lot of testing I’ll say the XA2 connections are not as good as in the X, but the same phone connects a lot better on Android than on Sailfish. So my XA2 will still be lying idle until I can test with the next Sailfish update.

After re-flashing Sailfish I found a few bugs in connection with setting up mail accounts. I’ll check if these has already been reported otherwise I raise a bug report on these findings.

But let me say, after now having spend hours testing on Android, I am SOOO happy that I’m using Sailfish on my daily phone :-)).

This is a totally different issue, please raise a new question.
