They had it in today's Q&A and I read it several times in the forum and in the chats that notification system is quite a mess in noble. There seems to be worked on though. Strange: it worked on my fresh install for about a day, then got more and more confused. First the counter of dekko in the launcher didn't stop counting, then teleports notification sounds disappeared, then cinnys. So it seems to be not only an issue of upgraded devices.

I just checked the upgrade channels in system settings and they just do not appear. I will try again after next reboot.

@libremax @AppLee I decided to buy a used Volla Quintus and posted my first experiences here:
https://forums.ubports.com/topic/11616/installation-experience-ut-on-vollaos-15

I bought a used Quintus with VollaOS 15 on it. The multiboot function didn't work. So I installed Ubuntu Touch 24.04-1.0 stable on it using the UBPorts installer. A very nice person on https://t.me/hello_volla explained to me that it wasn't necessary to downgrade. That seems important to me.
The installer even took care of unlocking the bootloader. The entire installation went smoothly. Great!
Almost everything works, even Dekko2, notifications, word completion, camera including video recording. I have 5G and I think even Volte (how can I check that exactly?).
Unlike what is stated here: https://devices.ubuntu-touch.io/device/algiz/, I can't get the headphones to work via the USB output, but that doesn't bother me. Fingerprint does not work too, but thats a known issue and doesn't bother me either.
One small bug: In the launcher, the Dekko2 icon doesn't stop counting; only restarting Lomiri resets the number.
Overall, I'm totally amazed!

There's also a Telegram channel for UT: https://t.m/utonvolla. Unfortunately, I don't know the Matrix chat (anyone?).
So this is my new daily driver and I will report issues from time to time. Thanks to all the Volla and UT devs for their amazing work on this port.

@Linuxlite76 In my experience this issue is device dependant, port dependant and different in rc, stable and daily channel sometimes, so its a liitle guess and hit

@adorsaz On my oneplus Nord 10 5g I am still not receiving sms neither on the latest rc nor on daily. I had to revert to stable. There its working. Did write that to the porter on telegram, too. Maybe device specific?

@AppLee Thank you for your quick answer and your work anyways,its higly appreciated.
I cannot decide myself between a brax, a volla quintus and a fairphone 5. With all your knowledge and experience which one would you recommend at the moment? I obvioisly need assistance to spent loads of money...

@MrT10001 Me and another person here on the forum tried upgrading Sony Xperia X from focal to noble, but failed. It is stuck on the bootlogo and one of the devs or porters wrote that they are still investigating in it. So the Sony Xperia X is on the list of non upgrded devices.

@MrT10001 Thanks for the list - Maybe you could add the Sony Xperia X devices to the non- updated devices ließst.

@Linuxlite76 sometimes it takes up to two minutes in my device until mobile data come back. So its maybe simetimes a matter of patience

And these are the logs from the moment I switched back to stable.

Hope it helps.

@gpatel-fr https://dpaste.com/2DPWCA7DB
there is only one entry saying that the phone number is not valid followed by the name of my provider.
Sorry, I am just a normal user, I cannot read logs. I do not know how to mask the telephone numbers as well...

Does somebody has informations about the quality of the hardware and the porting process of UT?

@gpatel-fr I switched channel and went back to stable. (In daily sms didnt work either). All sms which I had not received before arrived at the same time.
Are you interested in the logs from now?

@as1234 No, DO NOT lock the bootloader again, this could brick your device! See the notification as a kind of "your free from android now".

Nobody conforming notification issue and missing sms???

@lazarus Uhm, I see, but when I look here:
https://devices.ubuntu-touch.io/device/suzu/
its not listed. And not maintained, too. I tried myself to upgrade it to noble and failed the same way you did. So the two lists are confusing...

@lazarus Are you shure the device does support noble?

@gpatel-fr Unfortunatly I dont know. Thanks for your help anyway!
