[Qualcomm} VoLTE call for testing

Eric H · 23 Oct 2024, 08:09

I'm working on the POCO X3 NFC (surya) port with the maintainer and I tried Marius' changes, without success.
The device is 4G only, and there is no android.hardware.radio@1.5.so (android 10).

@mariogrip
Is there a way to make VoLTE work with radioInterface = 1.4 ?

Interestingly, these Miatool devices also have Qualcom chipsets. However, Xiaomi and their questionable Android 10 versions wherever the difference is. Partly the telephony does not work then it is no wonder that somehow there is no porter for Miatool devices at the moment. So should work exactly like this method presented by Mario. However, I am not a porter and no longer on Ubuntu Touch.

Finally, after commenting on the IMS services lines in the file init.disabled.rc the VoLTE works with radioInterface = 1.4 on POCO X3 NFC.

Some features don't seem to work properly anymore.
I will report on the issues encountered after a few days of testing.

VoLTE enabled on RN9P (joyeuse) too.
Despite most the issuing or receiving VoLTE calls failed, it's very promising! When calling, oFono shows 2 dials at the same time and hanging up is not possible. The callee has not call indication.
I was able to make a successful VoLTE call somehow. I could hear ringing then could talk for about 20sec and all of a sudden the call dropped itself, leaving oFono unresponsive.

On the Mi 6. radioInterface = 1.1
VoLTE cannot be used
Although he has already executed the following code

Congratulations on this successful VoLte attempt on Joyeuse. Exactly my device. May I ask you a question? Do you know which Android 10 version you used before you installed Ubuntu Touch (Xenial, Focal)? If you don't know anymore, no problem, at least now I have hope to get back to Ubuntu Touch at some point. If VoLte works better I think I will come back. Does it work with dual SIM or only on 1 SIM? I might have to install Ubuntu Touch again myself to test it. Only with this script or code from Mario I would definitely need help I'm not that good on the terminal

*Enrico13011978* · 24 Oct 2024, 19:33

I have now installed Ubuntu Touch especially for this VoLte test. I have probably done everything wrong that can be done wrong. Installed the Ubuntu Tweak Tool because of the write permissions. Then off to the terminal and installed the system with sudo apt update&&sudo apt full-upgrade and the Ofono stuff. What can I say, suddenly there were no more SIM cards available and my WLAN data volume was used up, so that went down the drain

@tigerpro I'm getting the same thing and I'm sure I've got the package spelled correct. When I do an apt update, I get an error:

Archives directory /var/cache/apt/archives/aprtial is missing. - Acquire (30: Read-only file system)

I new here, so apologies if I'm asking an obvious questions.

Platform: Latest Ubuntu Touch installed on Google Pixel 3a XL with AT&T Prepaid service in the U.S. and planning to purchase a FP5 in the near term.

HI and welcome @JDee-Intl

You might be in the wrong place.
This post is about testing out the VoLTE plugins for the Fairphone5 and I surmise you just tried to install some deb packages like it would be a regular debian based OS.
This is a common mistake, but the rootfs is readonly on Ubuntu Touch and apt is not supported, it is restricted to developers for creating the image we can later use.

Keneda · 7 Dec 2024, 02:13

@AppLee
He is not mistaking, see there :

Well, he is mistaking because he tries to install VoLTE on the wrong device, but installing it on the good one, Fairphone 5, needs installing via apt.

AppLee · 7 Dec 2024, 11:04

@Keneda
I realized ; see there: https://forums.ubports.com/post/83786
:winking_face:
Using APT is expected in the "porting phase" so to speak.
And I wasn't sure they realized that testing VoLTE is not something any user can do but needs porting skills...

JDee Intl · 7 Dec 2024, 16:52

@Keneda My mistake...I thought I read the port may work for GP3aXL (<- Oh, that's a horrible abbreviation), so I was experimenting.

JDee Intl · 7 Dec 2024, 16:59

@AppLee Now I see, said the blind man! I could not figure out why I couldn't write to the filesystem as root and sudo didn't work with the phone PIN. It's read-only because the entire filesystem is laid down during the porting process and thus only modified by the developers and then included in the port by the porters.

I'll get back to learning the porting process and waiting for the FP5 to go on sale! LOL. Thank you and I hope I'm not stating the obvious, but this is definitely helping me and hopefully others who get involved and read these forums.

Inali · 15 Jan 2025, 15:30

Maybe this should be moved to outside the FP5 forum? It's chocked full of people who aren't using the FP5.

Inali · 15 Jan 2025, 16:00

Regardless, on build 177 for FP5, I have successfully registered 5G and VoLTE and was able to call my voicemail, but the older issues persist.

Those being dialing my voicemail PIN doesn't register, and I cannot hang up the call and am forced to restart the phone.

After rebooting the phone, VoLTE comes back but as soon as I make a call, cellular shows 0 bars and after a moment it comes back with full LTE with no VoLTE. Rebooting the phone again shows LTE with VoLTE but calling again drops cellular entirely and it comes back with LTE and no VoLTE.

If curious:
phablet@ubuntu-phablet:~$ gdbus call --system --dest org.ofono --object-path /ril_0 --method org.ofono.IpMultimediaSystem.GetProperties

@Inali If you are using 24.04 Noble the other issues are probably best mentioned here https://forums.ubports.com/topic/10688/this-week-in-development-week-52-2024/80 of the FP5 telegram group https://t.me/+uGo3xe899gwyNmNk

@Lakotaubp
I am not using Noble. I had no idea it was even around yet until today.

JDee Intl · 5 Feb 2025, 22:37

I've got a new FairPhone 5 in hand. Just need to know which version of Android to install. Instructions say "base version of Android 13", but Fairphone is shipped with it's own version of Android called Fairphone OS (which was 13 until it upgraded to 14).

So, do I need FairPhone OS (based on Android 13) or where is the base version of Android 13 that I should use?

Thanks in advance!!!

kugiigi · 6 Feb 2025, 01:51

@JDee-Intl Ideally, you have to flash the latest Android 13 from their site. Fairphone OS is Android so they're the same. Latest Android 14 would also work however when I tried that on mine, Fingerprint wasn't working. I'm not sure if that's the exact reason though. Maybe you can try it yourself see if it's the same
In any case, Android 13 is still recommended to avoid issues that is not consistent with other people.

Also, this isn't the right thread for this
