    LineageOS is fine on non-Pixel phones. Some versions even support SELinux Enforcing, OTA updates and a relockable Bootloader.

    I hope they will use many GrapheneOS features like:

    • hardened kernel and malloc
    • sandboxed Play services instead of the insanely insecure microg
    • Vanadium Webview, Browser and PDF viewer
    • Auditor, Camera, etc.

    While LineageOS may have some security and privacy features, it is not a privacy- and security-focused operating system for phones like GrapheneOS, nor does it have nearly as many security enhancements or privacy considerations like Graphene.

    Everyone needs a phone. Not everyone wants governments and corporations tracking their every move and spying on their communications. CalyxOS lets you have your cake and eat it too, with "Privacy by Design".

    /e/ is a fork of LineageOS that aims to be completely free of everything Google. Not only that, but there are a number of goals the developer has in mind for /e/ that more people feel are vital to a mobile operating system.

    Its just fancy LineageOS. I think their GUI and some tools are cool, but they need to base off GrapheneOS to be Legit.
