    Limited in devices, there are very few devices availables and they have no plan to make it bigger. It's a dead project with no future.

    Excellent Android fork focused on privacy and security. Only works on Pixel phones. Sandboxed Google Play Services feature allows compatibility with almost all Android apps while limiting Google's telemetry and admin privileges.

    /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.

    Comments about /e/ as an Alternative to Android
    Comment summary: /e/ is praised for its focus on user privacy and being de-Googled while retaining Android's user experience. It supports numerous devices, offers a smooth experience, and allows app installation choice for privacy. However, some users note its limited device compatibility and concern over credit to LineageOS. Overall, /e/ is valued for privacy without sacrificing functionality.

    It provides freedom to use alternatives that seem to eb quite deeply embeded in Andriod. And while LineageOS does try to do the same thing, /e/ works very well and is easy to use.

    It's based on LineageOS and it uses all the work done from LineageOS and didn't give the credits for it. /e/ does not produce anything, but steals other's work.

    New mobile operating system running full GNU/Linux. Has a similar interface paradigm to Android (widgets etc) making it easy to adjust to.

    Only negative is the current lack of mobile applications. However, it has a large selection of desktop applications. Using this OS with a stylus should circumvent this issue.

    It's an alternative, though it still very dated on appearance and pretty limited.
