There’s a few projects out there to get Linux onto phones & make it a reasonable user experience. It will probably always be a very niche segment. Postmarket OS looks promising too but I haven’t been able to try it as my old pixel isn’t supported. Depending on your galaxy model it might be supported.

Fairphone is another one to watch. They make phones & you can pick the OS when ordering

I’ve played around with Ubuntu touch from ubports foundation on an old pixel 3a. It works ok as a basic daily driver. Depending on the phone model there’s support for waydroid which helps with using android apps.

The biggest thing that put me off instantly was the prices tag. However it sound interesting with what they’ve done
