Miatoll has currently working VoLTE on devel channel, only thing you need it to switch channel and upgrade system, it should be working without any change on SIM 1 when enabled LTE (4G) network, not the other SIM 2 slot

Disabling gl in the command line gets it to boot, as in: qemu-system-x86_64 -enable-kvm -m 2G -device virtio-gpu -display sdl -netdev user,id=ethernet.0,hostfwd=tcp::10022-:22 -device rtl8139,netdev=ethernet.0 ubuntu-touch-mainline-generic-amd64.img However the latest version is hanging at boot with starting VPN (VPN? LOL!).

Hi @Plarde Thanks for your contribution. And you're right, it's important to discuss such matter. I don't know how involved you already are in the system development. I'll make the assumption that you're more an app developer from the argument you made. So I don't want to go too deep as this is a topic that I don't master. One argument that can be made against it is that it will make the system image grow even larger when it's already too large for some devices. So the current situation is that such library/framework have to be packaged within the click. I guess the clickable template with already included SDL is a very good idea and should help developers wishing to use SDL tremendously as not many people are familiar with clicks and it can be cumbersome to build a simple app... I'll let other people prove me wrong or go deeper in the explanations. Kindly yours.
