N.E.P.T.R

Understandable. I wish there was a secure alternative to GrapheneOS on non-pixel hardware.

If you have a supported device, GrapheneOS is the better choice because it supports relocking the bootloader with a signed ROM. This is integral to the Android security model. I don’t have anything against LineageOS, just not something I recommend anyone daily drive because of the security risk.

Definitely don’t install /e/OS or IodéOS because they are substantially worse for security.
