Are you fine with having non-open hardware and using Ubuntu Touch or Sailfish OS instead of more mainline linux releases*?

If so the there are a multitude of devices that are supported in one way or another:

Community Port supported devices for Sailfish OS - https://wiki.merproject.org/wiki/Adaptations/libhybri

Official Sailfish OS devices (third party site, list is accurate however) - https://jolla-devices.com/sailfish_devices

Ubuntu Touch devices - https://devices.ubuntu-touch.io/

Also note that the Volla Phone just started shipping and is a more open hardware option from what Im told to use on Ubuntu Touch and others - https://volla.online/

*. Some users have strong opinions on these OS’s, Ive used them both and liked things about each of them and think theyre well worth a try. They do both handle packages differently (compared to each other as well as Manjaro ARM or Mobian for example) however so keep that in mind
