Moi? I use currently a NOTE 20 ultra 5g. Probably my second best phone, I only hate the fact it’s so massive (I miss being able to use just one hand for my phone) and the mediocre battery life for someone like me that watches a lot of videos. But the S pen is so handy those few times you need it.
Okay time to show my ignorance lol. Can you offer a resource on what a sandboxed browser is and what kind of tinkering is required??
If you use flathub linux store, many apps will come “sanboxed” ie they will have restricted permissions on your system. This whole another lesson on how linux works.
Either way, in order to use the web installer, you need browser installed on “system” which i think means your normal user permissions which would allow you to use the web installer.
If you are having issues with web installer, command line still works.
I think easiest way is to install chromium as system to this job.
