What do you mean ? There is ubuntu touch working in some phone.

I saw that there is some improvements, for the fair phone 5 it seems that it is working but no dual Sim possible and LTE phone calls. You can check it out for your model on this site : https://devices.ubuntu-touch.io/

For that I knew, though thank you for your answer :) have a great day !

Thank you for your informations, it may change my way of doing from now on. I appreciate it Have a great day !

Can you elaborate about having malware through unsubscribe buttons ? If you have some exemple too to facilitate my research it would be great. Have a nice evening
