@adorsaz

Thank's by the way, can you tell us if the "Lock"/"Unlock" trick works for you to make "Enter" and "Backspace" of the virtual keyboard work?

Yes if I lock the phone while Signal UT is foreground, these two keys work well after unlock.

Then I can switch to other application and go back to Signal UT and it still works without need to do the trick again.

Hello,

I used to use LineageOS on my Fairphone 4 without Google Play Services or the alternative MicroG.

I don't recall all the details, but the location service worked really well with the Fairphone 4 in this setup. If I remember correctly, the first location fix took some time, but after that it was very quick every time I opened the GPS application (first OrganicMap, then CoMap), and accurate enough to guide me while driving.

As I did not install Play Services, I think the Fairphone 4's hardware works well, and we should be able to leverage this to improve the location experience with Ubuntu Touch.

However, my experience with Ubuntu Touch today is that it's not reliable enough. I opened CoMap in Waydroid, stopping the Location Service in Ubuntu Touch to avoid conflicts. Then, after driving my car for about seven minutes and four kilometres, I finally got a location fix. Speed data became available much later, by which time I was already on the motorway. The location was not precise enough to guide me correctly at a crossroads.

I've checked the specifications of the location hardware again, and the Fairphone 4 seems to have all of these services available: GPS, A-GPS, GLONASS, BeiDou and Galileo.

Does the Ubuntu Touch location service use all of these or only GPS? Do you think support for Galileo, for example, could improve the experience?

Hi!

Thanks for the this work, it's really cool to be able to receive and view Signal messages without needing to open the whole Waydroid stuff

I'll take a look to the way you did it, as I've seen there's an unofficial Dino application snap package available (this is an XMPP client). I'll check if I can port this application using same techniques.

On a Fairphone 4, I've migrated from daily build (19th October) to this RC, I confirm I am still able to use VoLTE to make a call.

Although I cannot send SMS to recipient with phone number formated with my country prefix (+41).
I share log here with redacted recipient phone number:

sms_send.log

Edit: during the day I was able to receive VoLTE call and receive SMS.

I took time to test with the different update channels available and VoLTE works with current 24.04-0.1/daily channel (update 2025-10-19/3).

I've just opened an issue on Gitlab so developpers can check the logs and ask me more of them if needed: https://gitlab.com/ubports/development/ubuntu-touch/-/issues/2281

Here are steps I've just followed:

1. Flash Android 11 stock image from fairphone website
2. Start Android 11, configure phone
3. In mobile settings, uncheck VoLTE and check it back
4. Same for wifi calling (uncheck then check)
5. Make a call and check it's working well with Android. My operator has disabled 3G, so this check ensures me the VoLTE is well working on Android

Then, download UBports Installer 0.11.2 and start the process to install Ubuntu Touch 24.04-1.0 stable channel wipping user data.

Phone seems connected to 4G: the network status icon has letter « L ». Although voice phone call did not work.

I tried to call my Ubuntu Touch device with another Android phone and I didn't received the call on the Ubuntu Touch one.

I tried to run the gdbus command and I got same result than you (neither registered, nor voice and sms capabilities).

On a new test, I've started journalctl -f and I attach the result here. Let me know if more logs are needed.

voice_call.log

Note that before doing the call, I disconnected wifi to be sure to use VoLTE and not VoWifi.

@Ben-LinuxMan My provider is Yallo too and the VoLTE is working on my LineageOS installation with the Fairphone 4.

For your information, I share below screenshots of the current Android APN confugurations. Maybe that could help you to set up VoLTE on Ubuntu Touch ?

With the Ububtu Touch noble just released, I'll try to install it again in next days and I'll write here if VoLTE works for me.

@stanwood thanks !

Nice to see Swiss users too

Hello,

I'm using Ubuntu Touch since January on my Fairphone 4.

Some days ago my phone service provider emailed me an annoucement about the near shutdown of 3G network. They provided me the information that I have to use VoLTE to be able to continue to make and receive calls.

My provider is Yallo in Switzerland and it uses the Sunrise network. Sunrise will shutdown the 3G network next June.

My question is: should the VoLTE option work with Fairphone 4 ?

The device information here say no, but it seems some recent developments happend on VoLTE.

I see a switch on Ubuntu Touch setting to enable the VoLTE but it seems disabled. Is there some thing to do to enable it like using stock Fairphone OS ?

Edit: I'm runnning the Ubuntu Touch stable channel (focal OTA 8). I've let default phone provider access point configuration (only "internet" is enabled, no MMS neither LTE). My phone is connected with LTE already.

@AppLee another way for application developpers is by using the libsecret protocol to ask a user session service to store sensitive data. Gnome-keyring is such a service which creates by default a key store locked by the current user password.

IIIRC the KDE/plasma service is named kwallet.

Although, IIRC Ubuntu Touch lets user use phone without password/pin code. Maybe this is the reason such service is not provided to app developpers ?
