I want a Linux Phone

Hi everyone. I've been a Linux PC user for quite some time now. and discovering the world of Linux I have a strong desire to convert my phone to Linux too.

I tried to find out something, but from the little I could find, I only know that there are few options and they are not at all comfortable/functional.

I'm here to ask for information and clarity:

it's true that at the moment it's not a valid option to take?

Do you have any recommendations for distros to try?

I think it would be great to have a good mobile distribution

Thank you in advance for your answers.

EDIT: my phone is a Redmi note 15
