@Vlad-Nirky I will mark the thread as solved although I couldn't reproduce the orginal faulty conditions of France (Orange/ 1&1).- Maybe next time...
Thank you for your answers!

@Keneda @arubislander
I tried to reproduce the behaviour in France:
Getting the state " no simcard present", I removed the simcard while ubuntu touch running. But when reinserting the simcard, it was automatically re-read flawlessly...so there was no chance for me to test under the conditions I had in France - that was a running ubuntu touch with a simcard correctly in place and the phone showing "no sim card present"...
Of course, the command given by arubislander worked, the simcard was re-read; but the conditions were different from France, where the sim was not re-read/ couldn't be reactivated, although being in place untouched.
Here in Germany there is no more problem. The phone has still its secrets as it seems...

@Keneda ...not yet. I will try later and tell you. Please let me a few hours..., thanks...

@Keneda Putting plane mode on then off does not work/ doesn't change the "no sim card detected"...

@Vlad-Nirky The card works well again since I am back from France = no cut offs any more.
Sim card itself and contacts inside phone were o.k.
Card worked in France flawlessly. But it was completely cut off up to 5 times a day with the phone lying on the desk without touching it and I had to restart the phone to get it working again...
So I thought on the possibility (?) to re-read the sim card from command line without restarting the phone...

Any suggestions?

Had issues in France using roaming and beeing cut off the phone/data net (no sim card detected...) many times during the day. Is it possible to re-read the sim card with a command in the terminal? Or is the only solution restarting the phone?

@ikoz looking for this?

@captainfunk When enabling GPS, then starting PureMaps, PureMaps shows me when the fix has ended with the circle on the right side becoming bright. Then I can center to my location by tapping on the bright circle. Correct result.
Then I close pure maps starting test_gps in terminal with NO result, showing no values as you described.
Then starting GPS Toolkit working as exspected i.e. showing the correct results also. Then closing the app and then trying the test_gps command again with no result again i.e showing no values.
The other two apps still showing the correct results.
So my personal conclusion is that the test_gps command itself doesn't work correctly for a reason I don't know for PureMaps and GPS Toolkit working o.k. at the same time...

@captainfunk
Hmmm, maybe an issue of test_gps command?
For GPS-Tools app give the correct values...

@messayisto
...switching the mask symbol to "on" (=save device info) works for me. Thank you for the advice

After doing the core-apps update, the camera photos are saved 90° rotated to the left.
When taking a photo in portrait mode, the Gallery app displays in landscape mode and vice versa.
Switching the rotation lock doesn't help...
Did I miss something?
Please help...
Thanks.

The problem in preview app is still there. Behaviour of Morph and Filemanager view itself is o.k., so the changed orientation (landscape/ portrait) is read correctly by these apps.
Only the preview app has this issue. Anything I could do?

After the new update the Fahrplan app is working again. I am happy; thanks a lot for your work.
I'm marking the topic as solved.

@lduboeuf thank you for the response, I wrote a ticket to the maintainers of the website; but I don't have too much hope, for there is no problem to see the website flawlessly with newer Android or Firefox versions...

Good evening,
since a few days I get the error message "Object.hasOwn is not a function" when trying to open for exemple the following page:

https://www.aerzteblatt.de/news/bundesamt-warnt-vor-sicherheitslucken-bei-wearables-06829337-3cab-4030-81a3-c846a4e1b9d7

Is the error message due to our old Morph browser, possibly a Java-Script issue? Can I do anything to read again the linked articles...?

Into the bargain the contents of my bug report cannot be reached (any more?) via UT on Github...we need a better browser - but that's another story...

Hello folks,
could anyone please suggest me a way how to do a printout of an SMS thread? Using history.sqlite database of messaging app and some Linux program...
Thank you for thinking about!

Fahrplan2 app stopped working for me since some days. Station searching impossible, searching for connections stops with endless spinning wheel...
Anyone affected also?
I already filed a bug report on Github...
