@stanwood I also live in Switzerland I've got Fairphone 4 running 24.04-1.0 Beta 2 and my carrier is Yallo. 4G VoLTE is turned on but is unfortunately not working. In the Ubuntu Touch Docs ( https://docs.ubports.com/en/latest/userguide/dailyuse/volte.html) one of the requrements is „Ubuntu Touch contains a VoLTE configuration for your carrier.„ Does anybody know how to create such a configuration?

@dafeihong for me it helped to open a maps application like Pure Maps, disable the screen lock and leave it in the window for a while.

Have a look to Redmi Note 9 Pro: https://forums.ubports.com/post/85393

Hi @amazones. Thanks but Emacs is not my cup of tea.

@Simmonz I have moved your topic so that it is more clear to everyone what device you have. That was relevant for your question, but you did not specify it at the start.

@Simmonz If you are familiar with mtk client you can unlock the bootloader from there too since Volla devices have mediatek chipsets.

@ChromiumOS-Guy Option 5 without the fur and thanks for your work.

@lduboeuf Well, I didn't try to reset the APN, I am scared that nothing works afterwards. I will try the terminal command proposed by Wally (I hope this won't have bad effects on SMS) and if nothing changes, maybe I will try to reset the APN. I won't try a reinstallation, I am not expert enough of UBports (that's why I bought this second-hand smartphone with UT already installed). If I cannot succeed in fixing the problem, well, my daughter will live without MMS (but it's a pity because this is our only way to exchange pictures during the week when she is on boarding school).

@smoore100 You may have to look at installing the minimum Android version requirement before going to UT. You can check with the Volla guys which one is required before upgrading to UT. Cheers.

@stanwood said in Call for testing: Ubuntu Touch 20.04 OTA-10: So, how will the update be rolled out to users on the stable channel? (OTA-9). Will they first receive the update to 20.04 OTA-10, then immediately afterwards the update to 24.04-1.0? Or will they have the choice between the 20.04 OTA update and the 24.04-1.0 update? I must admit that I myself am a bit lost in all this 20.04 OTA-9 users will first receive 20.04 OTA-10 as an usual update. After that, they'll be offered an upgrade to 24.04-1.0. Users can choose whether to upgrade or not. I'll try to make this more clear in our release announcement blog.

@wally Does shows L when calling , here..not LTE .

Not the only one. I was also surprised plugging in my usb-c headphones did nothing. Generally it should be noted that this is about headphones with an usb dac. There are also adapters and headphones that pass through analog audio over the usb-c connectors, and those apparently work. These are the open issues that have been reported so far: https://gitlab.com/ubports/development/core/packaging/usb-moded/-/issues/6 https://gitlab.com/ubports/development/ubuntu-touch/-/issues/1912 https://gitlab.com/ubports/porting/reference-device-ports/halium13/volla-phone-quintus/volla-algiz/-/issues/3

I couldn't really leave it, so I just tried again, and now it worked? I did: Double Checked: Android is version 11 (Build fp4.fp4k.a.179.20230116 $ fastboot flashing unlock FAILED (remote: ' Device already : unlocked!') fastboot: error: Command failed $ fastboot flashing unlock_critical FAILED (remote: ' Device already : unlocked!') fastboot: error: Command failed Checked All three boxes (Including User Wipe)... Maybe you were right, Luksus (and thanks!), that I somehow missed the first check box, but alas, I'm a happy camper.. Regards Grisen

The Signal gateway for XMPP is also working again, in case someone prefers that.

Indeed, this is a general issue with 20.04 OTA-9, and is not related to VollaX. Some apps fail to update. I guess that there's something regarding with 24.04 compatibility layer... For now I ignore those updates, and will wait for the next OTA-10 / 24.04-1.0 to update them again. [image: 1757793889979-photo_2025-09-13_22-02-17.jpg]

@MrT10001 I genuinely cannot believe that fixed it, thank you! It cruised through the process this time, and UT is now installed

@johndoe said in using Ubuntu Touch as o/s for IoT devices with RPi/Rockchip: A specific mobile DE, you could also look into, is Phosh. But it will probably not work with your remote access software. Whereas Lomiri is known to work with VNC at least. And it is in the debian repo's as @Vlad-Nirky already mentioned.
