Android uses forked versions of the Linux kernel, based on Linux LTS versions. They added in Rust support in 2019 and most new code since then has been written in Rust in order to avoid memory safety vulnerabilities. And memory safety vulnerabilities have been significantly down since 2019.
Now that upstream Linux is adopting Rust, we should hopefully see a similar results. Though likely slower than Google (they went all-in on Rust) while upstream Linux new code will seemingly be mainly C for the foreseeable future.

is it? From what I read the old kernel developers are really opposing it
Linux support is definitely moving slower than the Rust team wants, but the team and Linus are still optimistic.
