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.
