I still have my first Jolla from 2014, I used it until... 2022-ish? My main gripe was that RAM was limited, the OOM killer killed my browser way too often while I was actively using it. I didn't use too much Android stuff, but as far as I remember it mostly worked. I'd expect this new one to work just fine.

The thing that sounds really fishy is the "User configurable physical Privacy Switch". If you can configure it in software (how else?), then it's software-defined. If it's software-defined, then it's not physical.
