    Mobian

    Mobian

    Mobian

    Mobian aims to integrate the standard Debian distribution with the Phone Shell (phosh) project in a package that works on certain mobile phones, such as the Pinephone. Over time, the idea is to minimize the Mobian specific pieces by “upstreaming” customization to the original projects. Mobian comes with Phosh, the Phone Shell by Purism. It is based on well known modern Gnome technology like GTK, GSettings and DBus running on a wlroots based wayland compositor called phoc. Mobian aims to integrate the standard Debian distribution with Phone-specific projects and modifications in a distribution that works on certain mobile phones and tablets, such as the Pinephone, the Pinetab and the Librem 5. The idea is to minimize the Mobian specific pieces by “upstreaming” changes to the original projects as much as possible. To achieve this, we tread a delicate balance between carrying customized patches and packages that are required to make Mobian run well on its supported devices.

    Fire OS

    Fire OS

    Amazon

    Fire OS is the operating system that runs Amazon's Fire TV and tablets. Fire OS is a fork of Android, so if your app runs on Android, it will most likely run on Amazon's Fire devices too. You can quickly check your app's compatibility with Amazon through the App Testing Service. As a developer, you might not have to adjust your Android code at all to publish your app on Amazon's platform. Most Fire devices receive over-the-air updates to get Fire OS updates automatically. Not every Fire device receives a push of the same Fire OS version at the same time. The updates often roll out to different devices at different times. At the core, both Fire OS and Android share the same foundation. The main way Fire OS differs from Android is in the services. Instead of using Google's services (for activities such as browsing, location, messaging, payments, and so on), Fire OS might use Amazon's services.
