[Qualcomm} VoLTE call for testing

AppLee

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.

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.

: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...

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

@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.

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

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

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

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!!!

@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
