Hi,
I just wrote a PDF reader based on Chromium PDF engine.
It's pretty dummy, written in 30 minutes. But quite useful (at least for me) given the limitations of Document viewer, and that sturmreader is currently broken on noble.
I think it will greatly benefit from Qt6 upgrade, when it comes, because of improvement of the engine in chromium.
It is published in the openstore:

Hello everyone,
I figured I would make videos about Ubuntu Touch, to contribute spreading the word.
I'm thinking about making videos to present my applications, reviews/demonstration/tests of the system in general, and possibly videos where I explain why I'm using Ubuntu Touch, and how I got to it.
Here is my first video presenting the application Maps exporter:
English version: https://www.youtube.com/watch?v=GR0eqz7wpyM
French version: https://www.youtube.com/watch?v=rOJkiSa28Ss
This is still quite experimental so if you have feedback on how to improve the videos for the next time feel free to do so! 
I've succeeded in opening the keyboard when editing text in signal-desktop !!!! 
I could do it reusing the work of @ChromiumOS-Guy in uWolf!
I can officially send signal messages from a native Ubuntu Touch app, without Waydroid! 
Even though for now it's not convenient , since keyboard hides the text area, and the enter button of the keyboard somehow does not trigger sending the message, and the "send" button in signal is hidden until you expend the editing area. But still very usable.
For now everything is messy, but I will try to make it available soon (I think it should be possible to do a click package, but I'm not sure yet)
Ps: Note that I could do it with Mobian version only for now.
Hi,
Just wanted to share that VLC 4 (not yet released) has an interface very close to VLC for Android.
I will be a very good candidate to port to Ubuntu Touch. The interface would probably be usable as such, but with few minimal patches to the interface it could probably be near perfect on the phone screen.
I don't have time to do that now, but probably later (possibly when release officially)
Hi,
Just wanted to mention that I contacted the in-development French identity mobile app, to ask them for interoperability, and remind them their duty to make sure public service is available for everybody, and that their role was not to enforce the choice of mobile OS of their citizens.
https://france-identite.gouv.fr/
Surprisingly I got a pretty open and positive reply, apologizing that their app was not compatible with my OS (Ubuntu Touch), and saying they shared the goal of interoperability, and would study that with the development team what was possible. I did not expect such a positive answer, although I don't know if anything concrete will get out of this.
As a side note I wonder why for this kind of app, with a real need of interoperability, they don't use more Qt, because from what I understand Qt allows to develop apps for Android, iOS, Windows, Mac, Linux desktop, Linux mobile (Ubuntu Touch, Sailfishos, Mobian, postMarketOs, pureOs, ect...), all at once, with only few custom things to go for each platform. Any thoughts on that?
Anyway after all the investigations that I've made I'm extremely confident that we'll be able to have a fully responsive client based on Signal-Desktop landed in the openstore within few month. I see exactly how to make it perfectly adapted to the phone Interface like whatsweb. (Funny enough it is possible to use a modified version of the js script of whatsweb to make the interface responsive, because the interface has an extremely similar structure. )
It's not anymore a question of "if" but a question of "when". But there are few tedious tasks in the way, and I need to go little by little, because I can't dedicate all my time to this.
Of course I'm open to any offer for help and testing!
Hi,
Today I just figured why not try:
sudo snap install signal-desktop
And I realize it just works! This is crazy. With this simple command I can link my device and see my chats. Well it is certainly not a responsive interface (but not terrible either, there's just the left menu coming in the way) and the keyboard does not show for now. But I can consult messages, and this is major.
It means:
1°) We can certainly create quite easily a version of Signal-Desktop that is adapted to mobile display (with few patches to the interface to make it responsive), and that we can get a full-fledge signal client on Ubtunu touch, that way.
2°) That Mir2.0 will certainly help with that.
Ps: I guess the first easy thing to make it usable as a consul-only stuff is adapt the scale, which I guess must be easily doable.
I've been able to recompile Signal-Desktop from source and apply my responsive script.
It is available in the Openstore alongside these other improvements:
-Fix startup from OpenStore
-Fix open url externaly
-Fix battery problem
-Fix double window problem
There still are some keyboard issues, it's probably the next thing I will work on.
First of, thank you so much for the development on Ubuntu Touch, it is becoming amazing!
I have a question about Wayland/Xmir apps (e.g uWolf, Signal-desktop, Snap apps) in the context of the upcoming Mir2.0
Will you consider implementing any of the following, to polish experience with Wayland apps:
Would you need/accept some help to do that?
They have not reached out to me again, but I would say every french citizen that use UT is entitled to contact them about this concern and the more they receive requests about that, the more they are likely to take it seriously. And I guess it is also possible to send them a message in the name of the fundation with an offer for assistance on the technical side.
https://france-identite.gouv.fr/contact/
Ps: By the way an argument that seems efficient to draw their attention lately, in the current context, is stressing that by not being inter-operable (as they are legally obliged) they are effectively offering a duopoly to 2 American companies, and preventing any potential alternative from emerging.
Although, to be fair the creator of the WhatsNew app has taken measure to suspend the app when it looses focus as well
I've not done that specifically in whatsnew. What happens is that normally when an electron app is not anymore in foreground it goes into a "throttling" mode meant to keep operating the website but with lower resources. This is a feature from chromium.
That being said I have no idea why XWayland/electron apps don't get suspended by default. For Signal UT or Whatsnew it is handy to get background notifications though.
The behaviour encountered by @smobilesoft (high CPU usage) is not normal , I've not been able to observe it myself, and it seems since he reinstalled the app it has gone. So this is a bit strange.
Ok well this is very strange.
Well it's possible that whatslectron take a lot of CPU on some occasions. For example when syncing messages. But this should not be a recurrent behaviour that drains the battery when the app is in background.
If there were 2 windows remaining this could explain the problem, but I don't see how uninstalling and reinstalling the app could have any effect on that, as you now seem to have the proper behaviour i.e the second window closing after few seconds.
But, so do you still have the battery drain problem?
Hum this is kind of strange as I don't observe anything similar. For me "Whatslectron" which is the process behind whatsnew, takes 1-3% CPU when in background (more or less the same that whatsweb consumed when unsuspended)
Question:
-What version of Ubuntu Touch are you using precisely? Stable or daily?
-When you use Whatsnew, when you go in the window carousel, do you see one ore two window corresponding to whatsnew, and what icon does it have under it?
-What is precisely the name of the process you see in top taking 100% CPU? Is it "Whatsnew"? "whatslectron"? Something else?
-Could you give me the result of "md5sum /lib/aarch64-linux-gnu/liblomiri-private.so" in your terminal?
Well it could help if when the battery is draining fast, you can go to the terminal and type "top", to see what program is using a lot of CPU.
I have 2 questions:
-Is there any ongoing plan to developing support for RCS? I think this could be the next blocking point for Ubuntu Touch, so I may contribute to a project to support RCS given that I can find time for that.
-What role and importance do you think offering options for all the most popular messaging protocols, have for UT's potential for adoption as a daily driver? Both the standard ones like SMS, MMS, RCS, email, but also the private ones like Whatsapp, Telegram, Signal, and even Facebook messenger?
Thank you so much for everything! 
You can try to update to 24.04 from the settings app in the update panel from your 20.04 install. Does it propose you the update there?
You should have a much better experience with 24.04 in the long run, and more compatible apps from the openstore!
VoLTE works for me, though sometimes the VoLTE connexion is lost after loosing network and does not necesarilly reestablish automatically.
I've just published version 0.1.6, that corrects the app that was broken by a change upstream in Whatsapp web;
Here is the changelog of the version:
I've only tested the main features, I've not had the time to do a comprehensive testing before releasing the new version, but as it was broken it's always better to have something that works. If you find any new bug, or thing that does not work anymore with this new version or since change in Whatsapp web, please do not hesitate to report.
I couldn't reboot with the power button since that was somehow blocked
I really don't think this can have anything to do with running Signal UT, including the patch I've shared above. I don't see how the app could have an impact on the effect of your power button. Especially because it's confined.
I can't close it, when swiping into the drawer, it becomes a transparent window which I can't swipe to close
I see that happening from time to time, including with other apps. I think it's more a Lomiri bug. Anyway you can just start another time the app, and kill the launcher indicator, it should kill the remaining transparent window.
Or if you want to use commands in the terminal you can try to paste this in the terminal, it should fix the crash in 24.04-2.x branch (but will not solve the OSK problem):
sudo sed -i "s/\[ \"\$?\" -ne \"0\" \]/\[ \"0\" -ne \"0\" \]/g" /opt/click.ubuntu.com/signalut.pparent/current/launcher.sh
sudo sed -i "s/\[ \"\$?\" -eq \"0\" \]/\[ \"0\" -eq \"0\" \]/g" /opt/click.ubuntu.com/signalut.pparent/current/utils/filedialog-deamon.sh
