Ask HN: Is there a viable non-android non-iPhone mobile device?

My buddy rocks a dumb phone. I’m highly tempted. I do kinda like having slack, email and Lyft though. Any viable alternatives out there? The big two are pretty annoying, aggressive, opinionated, and anti-privacy. I’d be happy with someone who just hasn’t had the opportunity to get bloated and forget that it’s actually about the customer. I remember there was an Ubuntu phone, a Firefox phone, some weird privacy first Black phone. Are any of these viable today?
