Jolla reached a huge amount of preorders for their new phone. Regarding Linux phones, this looks the most promising and could be a chance. Android forks do not challenge the issue with big tech, enough.

Jolla was effectively out of the phone hardware market for almost a decade. Things have changed dramatically sonce then. Small batch phone maufacturing has become a log more feasible. We will see if it is enough to survive but their SailfishOS has a very much alive community.

If that's a requirement, I think the Flx1 (no s) has one. You're lucky to find any phone without a headphone jack now, but they do have an option. Still, I'd trade no headphone jack for a Linux phone if that were required.
