Hi @danfro,

I just wanted to point out that someone has to take on the task of porting it; it’s a huge undertaking, and there’s a chance it might not work out in the end.

And, who here is willing to do the groundwork and look up the author’s questions?

Hi @danfro,

Well, we have a lot of forum users who are interested in a port for a newer device, and we can’t give them a clear answer either.

So, what’s the point of trying to figure out why the port for an old, underpowered device failed?

It just takes someone who’s willing to put in the effort, has the time, and owns the right device.

Hi all,

I'm not entirely sure how accurate the battery readings are from device to device.
According to the data, my OnePlus Nord 100 is said to have used only 7% of its battery over 13 hours. It was in standby mode most of the time, with only the phone's modem connected to 4G LTE.

Edited: Operating system UT 24.04-1.2 stable, and always put to sleep using the power button.

So this issue isn't important for every user.

Hello,

Oh, I see—it seems to me you're both lazy.

Hi @fredldotme,

Thank you very much for all the work you've done so far.

Have you already achieved your goal of “updating the kernel from 4.19.157 to the latest stable release, 4.19.325, from December 2024”?

hi @arubislander,

Well, but that internal ad banner that appears at the very bottom of a post when you visit the forum as a guest—that really gets on my nerves, too.

So I’d be fine with it alternating with a sponsored ad banner.

But that would probably have to be managed by someone—is it or isn’t it?

Hi @oldbutndy,

Welcome to the Ubports forum—it always takes a bit of conversation to get to know each other. Unfortunately, it’s still harder to do that through text alone.

As Moem already wrote

You're part of a community, there is no need to stumble around in the dark, come sit around the fire with us and we'll swap tales and information.

Now I’m ready to sit around the campfire too, but it’s a shame it’s just text—we’re missing body language, like a smile.

@oldbutndy said:

So, when you search for phones that might run UT, and make voice calls, in a specific country, just where are you supposed to look ?

In our forum, under the “Devices” category, there are quite a few posts from the community.

Unfortunately, the search function isn't great—to be honest, it's pretty bad. I think a dedicated internal AI would probably be useful here.

Hi @oldbutndy,

Sorry, the comment “nice to have” refers exclusively to the amount of information on the device page.
Of course, I too want phone calls to work first and foremost—which, by the way, worked flawlessly for a long time on 3G technology.

My point was that users should also take the initiative to look for information themselves. This would help UBports and the community.

But here in the forum, the performance of our very small organization—including the community—is constantly being compared to that of big companies like Google, Apple, Samsung, Xiaomi, etc.

I also think that anyone who wants to break free from the tech giants and big data
shouldn’t rush headlong into the arms of AI.

But, I’m probably too old to understand that.

Hi everyone,

Sorry to all the readers of my off-the-cuff post above—it turned out a bit harsh again.

All the information on the device page should be as accurate as possible, meaning it should have been tested.
Therefore, it’s better to have outdated but correct information than information that’s up to date but based on a single tester’s experience.

I feel the need to highlight the amount of work involved in creating something that’s “nice to have.”

First, there’s the OS: It’s maintained by the core developers. They have to ensure it runs on the current Android Hallium versions of the various ported devices.
The developers (all 5 or 9 of them—well, I don’t know exactly how many we have) must have a device running an Android version that we support.

The device ports: These are maintained by the porters and must be adapted; for example, to support the G4 wireless system or VoLTE.
Every porter is required to have such a device, and they probably only have one or two SIM cards to test.

Mobile carriers offer a network that, while standardized, is still not uniform. So, roughly speaking: 193 countries times at least 3 carriers equals 579 networks. Well, many of them are probably similar, so the number is too high, but clarifying this is still very time-consuming, isn’t it?

Please correct me if I’m wrong; this isn’t based on in-depth research. I’m just concerned about the amount of work involved.

Hi @oldbutndy,

I'm sorry to have to say this, but your expectations are pretty high, considering that UT OS isn't sold but is based on donations.
Anyone who uses free software should really be more modest, especially since so many people aren't willing to make a donation because the software usually doesn't yet meet all their hoped-for requirements.
That's my view, regardless of whether your concerns are justified or not.

Hi @MrT10001,

@MrT10001 said:

Just tested and VoLTE is picked up and seems to be working. My 5G SIM is in use so I cannot test that yet.

With 5G, VoNR is used for phone calls as a so-called standalone implementation.

However, the 5G NR standard also has a non-standalone implementation, which is responsible for the use of VoLTE. Therefore, I think it should also be possible to use VoLTE with a 5G SIM card.

However, not all mobile network operators may offer non-standalone implementation.

Hi DJac,

@DJac said:

since I switch to UT24.04, I have an error on the hour indicate on the device interface : he give me 1h less. I have to go to the parameter menu > date & hour... and it comme back to the good time (without other manip).
It appends 'sometimes' : i don't see the paterne.
I suppose it is a probleme with the UTC (I am +1).

I checked it on my Xperia X, and when the device starts up (power on or restart), the time is incorrect.

When you tap the <gear icon> for the settings menu, the time is set correctly, as is the time zone UTC+1.

I suspect that this also happens when the device itself triggers a restart due to an error in the operating system.

Hi,
I have a slightly different problem.
Oneplus Nord N100 (UT 24.04-1.2 stable) with Nissan hands-free kit <MyCar>. Pairing works without any errors, but the screen shows that no network is available. This means that I cannot make or receive calls.
image20260223_151514524.png

It seems that my hands-free kit cannot handle VoLTE, is that correct?

With UT 20.04 OTA 9 / on the 3G network, it was possible to make calls using the hands-free system.

Hi @DJac,

@DJac said in Call for testing: Ubuntu Touch 24.04-1.2:

In my case, the bluetooth stuff works too (a samsung sound speaker)

So far, I haven't found a device that plays the sound, but a Sharp radio with Bluetooth could play music from my Xperia, but with interruptions, and every time it resumed, the song played faster than usual, as if it wanted to make up for the interruption.

@DJac said in Call for testing: Ubuntu Touch 24.04-1.2:

I notice no vibration on sony xperia X. (at start, with keyboard...).

My Xperia has no problems with pressing the keyboard and the "echo" from the vibration.
Or have I misunderstood something?

Greetings

Hi @peat_psuwit,

about Sony Xperia X:

Well, I can confirm that the sound works through the speaker.

Bluetooth connects, but there is no sound in the headphones.

Now I also have VoLTE on the Xeria X, amazing.

Hi @rocket2nfinity,

As of today, I am on channel RC <24.04-1.2 RC> with my <Oneplus Nord N100 (BE2013)>.
Hurray, I am so glad that my horse is still alive. It is simply amazing, almost indescribable.
VoLTE is here.

I haven't tested everything yet, but phone calls are working, many thanks to all the Heinzelmänchen.

hi @stanwood,

Well, I'm always glad that forum readers take the time to read the posts before replying.

Since I started the thread myself and specifically labeled it “off topic,” I would like to mention that even the best cell phones and their customized software would be useless without telephone service providers.

Greetings
Mario

Hi everyone,

After further research on the internet, I came across IMS (IP Multimedia Subsystem) and was surprised to discover that VoLTE and RCS (Rich Communication Services)
are both somehow related to IMS.

And that the telephone service provider in Switzerland "Swisscom" had already discontinued the RCS service at the end of 2023 because it was hardly being used.

Well but Hello, everyone!

Thank you very much for your information.

I've been around long enough to know that a daily channel (i.e., dragon channel) exists in the versions, but I don't want it on my daily driver.
I can wait for the RC or stable channel, even though my attempt on the Samsung Galaxy S9 with E-OS failed.
I found the following post in the E-OS forum:

These international Samsungs don’t get VoLTE with any U.S. network, due to:

their internal hardware which is different from North America Samsungs and identifies as incompatible, i.e. non-certified for a particular U.S. network’s VoLTE; their exact model number + suffix is also different from the North American variant.

Samsung’s proprietary IMS/VoLTE implementation which no custom ROM can integrate (or so I’ve read).

Even U.S. variants of Samsung apparently can’t get VoLTE once a custom ROM is installed (unless something changes). Other OEMs don’t have this problem.

Any carrier can tell if a phone has or has not been certified by the OEM specifically to carry Voice over LTE on their network, just by the IMEI, which is visible to their systems; if not, then they will disallow it in countries like the U.S., where VoLTE is now a hard requirement. It would probably introduce a legal liability (inability to call emergency services) to them if they allowed a non-compatible phone on the network once all the 3G is shut down, and eventually 2G.

If a particular device has been tested and certified to use a particular network’s VoLTE, then a setting such as “Enable voice over LTE” or “Enable 4G calling” or “Use VoLTE,” etc., will appear in the menu when that network’s SIM is inserted. (Not to be confused with LTE data, which is not specifically referring to making phone calls.)
