Device recommendation for VoLTE support

AppLee

@kugiigi To clarify this, support for 5G and VoLTE are necessary.
Once that's solved, we can try to get that sorted and updated and hopefully have Fairphone selling devices with UT preinstalled.

@alagirialagiri There are a few people that are working on the Miatoll series to try to make VoLTE working. (I'm in the https://t.me/UTForMiatoll Telegram group). Even some (unsuccessful) attempts have been made....today.

So I'm sure it will get one day. Don't know how hard is the task though...

@kugiigi
There is official support from FP on the FP4 page.
See "contributors" part.
Also on top :

UBports builds this port in collaboration with the phone maker.
Expect long-lasting support since we have an official agreement with the partner.

Under furiOS, the FLX1 ( https://forums.ubports.com/topic/10861/new-flx1-with-ut-and-dual-boot ) is presented as supporting VoLTE. This may also be the case under UT. To be confirmed...

Has anyone tested VoLTE for fairphone 3/3+/4?

It is possible to obtain a list of all devices in devel where VoLTE is enabled by conducting a search on Gitlab :

Thanks @Eric-H for that list! Folk should note though that "enabled" is different than "functining properly". The list provided by that gitlab search includes devices that are very unlikely ever to see functioning VoLTE, such as Pixel 3a.
I find user reports on the forum very useful and would welcome more.

Regarding VoLTE on the Pixel 3a, this is a new port under Android 12 that was developed to enable this feature.
However, I am not aware of the current status of this port, nor whether the effort will continue or has been abandoned.

Alfred was clear that he cannot test this out.
So consider it abandoned, but if anyone is willing to push this further, he'll be able to assist, so it's open for contribution.

Hello all. I'm new here and love all the work you all are doing on Ubuntu Touch. In the United States, the Google Pixel 3a is cheap and readily available. Some of the other phones I've been looking at to run Ubuntu Touch are quite expensive to get in the United States, especially the Fairphone 5. I'd imagine the prices of any phone requiring imports could continue to increase.

Currently, I have been testing with the Google Pixel 3a. Alfred's work on this has been amazing. I'm sure all users of this device will agree! The only thing preventing me from using it as a daily driver is the lack of VoLTE. I'm able to get data over 4G, but I can't get phone calls. Phone calls only occur on 2G. On 4G mode, I can call out, but people can't call in. On 2G mode, I can call out and people can call in. For data priority, I have to switch it to 4G mode. For phone call priority, I have to switch it to 2G mode. 2G is important because I can only receive calls in this mode. The 2G/3G/4G mode won't swap the call down to 2G for me to receive it. I doubt swapping down to 2G is possible, but I could be wrong.

I may need to be pointed in the right direction on how to test. I'm not sure where the project left off and who all may be interested in continuing the development further. However, I want to show my appreciation for all the work done so far and see if this could potentially be taken further by a small group. I know Alfred is incredibly busy and can't dedicate as much time for it. However, for people in the US, the Google Pixel 3a presents a low bar of entry and great accessibility into the world of Ubuntu Touch for those who may want to try it out, learn more, etc.

If any notes can be left and a maybe a direction of where to go with incorporating VoLTE, that would be helpful! I don't know how I can help other than potential testing. I don't know anything about scripting for VoLTE, etc. However, maybe with some notes and research, a group can gather to learn more and help out!

In the worst case scenario that VoLTE won't come to the Google Pixel 3a, another phone recommendation may be needed for users in the US. If there is a phone recommendation that can run VoLTE, 5G, MMS, and Ubuntu Touch 24.04 that is in US, please let me know. I'd like to continue trying to see if I can make Ubuntu Touch a daily driver for me. Again, thanks for all you do!

Hi @atarilinux

Thanks for this message.
The testing required is technical.
I'm sure @fredldotme can (and is willing to) point you in the right direction to test things out.

Of course to embark on this journey, you'll need to have another daily driver as it will require to be on the devel channel.
Also it'll require to check various logs on the device to investigate the possible bugs and try to find a suitable solution.

It's not development per se IIUC, but more integration, so building the big picture, understanding how different component rely on each other and interact.
And some times when fixing issues or propose MR on those components.

If what I described is difficult to understand, maybe you can try to find people with the required skills around you. But if you understood but are not sure you can do it, I would encourage you to give it a go and see where it lands...
