Can't stay on Android because Google is anti-privacy. Can't get a GrapheneOS phone because they're only compatible with non-repairable devices. Can't get a FairPhone or Jolla because I live in America. Can't get an HMD because the bootloader is locked.
Even e/os and LineageOS have security problems.
There is no good phone on the market, to my knowledge. You can't have privacy, repairability, and security all at the same time.
