@arubislander Whether the article is helpful is up to you, it's not meant to be a reproach. After all, it was written 1.5 years ago that VoLte is coming, and then that was it on the subject again. The only thing to criticize about my contribution is definitely the time specification of 5-10 years. This was related to the longer time you were on the road with Xenial. In this regard, I assume that you will need just as long with the conversion as you did with the switch to 20.04. Good luck with VoLte on UT.

There is/was definitely a great tool for Ubuntu Touch to change icons and wallpapers. I think it's called custom-phablet-tools used it a lot on Xenial!
