The rationale for using LTS distros is being eroded by widespread adoption of containers and approaches like flatpak and nix. Applications and services are becoming less dependent on any single distro and instead just require a skeleton core system that is easier to keep up to date. Coupled with the increased cost needed to maintain security backports we are getting to a point where it’s less risky for companies to use bleeding edge over stable.
I assume you meant dialer app 😆 . But anyway, for some Android phones you can use call screening.
