It might be a known issue already, but on my XA2 I lose Internet connectivity on Android apps side. E.g. after reboot Vivaldi, Firefox and WhatsApp all work, but a day later or so, Vivaldi and/or Firefox lose connectivity, but WhatsApp keeps on working… It’s not just the first reboot, the situation persists.

Mmmh, I would say that this behaviour (bug) is common to all AD- / SFOS-releases on all supported devices.
I.e., I regularly experience this since 2015 (when bought my first Jolla 1) on Jolla 1, Xperia X, XA2 and 10.

Spotted exactly the same behaviour for the first time. After another reboot internet was restored. XA2 Dual Sim
A GUI method would be preferable.
Under the Xperia X it helped to restart either aliendalvik or reconnect to wifi/mobile.
Does anybody else have problems with Android-app-Support (here on Xperia XA2 Plus Dual Sim) with Kvarken 4.1.0.23?
It’s the same issue like 2 updates before:
Starting Android apps leads to the tile with the loading-icon, it’s there for half a minute, then closing.
Tried:
Unsinstall Android-App-Support with Jolla-Store, reboot, install Android-App-Support from Jolla-Store, reboot (with starting alien-dalvik at boot), same error…
The solution time ago was the sailfish-update. I let a post here to this topic but maybe it was on TJC, i could’nt find it here.
Kind regards!
PS: Aaaahh… found it, this was the thread describing my problem:
Thanks for reporting. I have fixed this typo.
Quite the opposite, actually. For me, since updating to 4.1 Android apps start way faster than before. Most of the times they now appear quicker than native apps and it definitely used to be the other way around before.
Is there an ETA on the Android and Exchange support for Xperia 10 II?

With 4.1 in an XA2 dual sim phone I have the SIM1 card as active. Then I go into Mobile netwrok settings and select the option to use “SIM2” under the data option, then the SIM1 is completely grayed out and cannot receive or place calls.
I seem to remember that in the past it was possible to have one card as primary and select the other one for the Internet Connection option.
I believe this is a bug.
I think it’s related to the one I always encounter. And not exclusive to 4.1. I clearly still remember…
I have been deeling with this Sim and network error ever since sailfishX became available on Xa2.(but somehow got better)
I have only Sim1 installed and 2 empty. But I have to keep them both enabled. Whenever I try to turn off the 2nd Sim, at some point, either immediately, after a while or sometimes after a reboot, network will fail and wouldn’t be detected. Until I restert the device.

I have seen this too on an Xperia X. In my case what I found was that when I had one SIM that uses Three’s network and another one that uses EE’s, the SIM using Three had to be selected for mobile internet for it to work at all, otherwise I saw exactly what you describe. When both SIMs used EE, or one used EE and the other O2, there was no problem.
Three publish this support article that claims it is connected with the fact that they don’t use 2G. I have no idea whether it is true or not that the X or XA2 cannot support 3G or 4G simultaneously on both SIMs, but in the end I had to transfer the number to a different provider to get the full flexibility of the dual SIM phone. Maybe more recent models are better, but I’m not about to buy one to find out

Are XMPP accounts fixed in this release?

I do remember this having happened before, but that was in the early SFOS 3 release or something… This bug in 4.1.0 EA is something else indeed; my phone does it at least once a day, and the only way out is a reboot. Stopping and starting Android app support doesn’t help, neither does visiting flight mode.

I think in my case, AFAIR, turning Sim2(empty) back on resolves the issue.So, I keep both 1&2 On all the time, and I then have no problem whatsoever . Especially after a reboot, works fine.
But why do you think, Android Support might be related ?
I only have a single SIM device - XA2 Ultra - but it could still be related to dual SIM support and Android app support… (Then again, my single SIM XA2 device running Android does provide the options for the dual SIM variant. So…)
I now would say there is definitely something wrong with power consumption!
I charged my device (an X) and kept it in flight mode over a day and night and it consumed 3% only. So far so good
Then in the morning I disabled flight mode, so network and WLAN were connected. I did not use it and in the late afternoon it was already down to 50%. I then disabled WLAN for some hours and consumption was about 1% only.
After that I enabled flight mode again but enabled WLAN. And power consumption is 3-4% per hour with null usage.
So WLAN connected with no usage at all drains the battery!

Yes. No apps at all.

AND confirmed overnight:
fresh boot, no apps open (except Jolla weather on home screen maybe), flight mode, only WLAN enabled and connected, lost 17% in less than 7h…
@jovirkku
Do we need to file an explicit bug report?
