The open-source project that keeps old smartphones running with a full Linux stack released postmarketOS 26.06 on June 21, delivering its biggest six-month update yet for owners of Android devices that manufacturers abandoned years ago. Built on Alpine Linux 3.24, the “Alpen Avocado” release ships GNOME 50, a switch from a custom boot splash to the widely-used Plymouth system, and a ModemManager upgrade that brings emergency cell broadcast support to Linux phones for the first time — all while expanding the supported hardware catalog to 254 devices in its testing category.
The practical reader question the release answers is direct: if you have an old Pixel 3A, OnePlus 6, Samsung Galaxy S9, or Xiaomi Poco F1 sitting in a drawer, postmarketOS now offers a more polished path to reviving it as a full Linux device than any prior release.
Why Your Old Phone Still Has a Software Life
Most smartphones stop receiving security updates two to four years after release, but the hardware rarely fails. The result is hundreds of millions of devices worldwide that are fully functional but exposed to unpatched vulnerabilities — the primary reason most users discard them, according to industry analysts who track device replacement cycles.
postmarketOS addresses this by replacing the Android stack entirely with Alpine Linux, running the upstream Linux kernel rather than the vendor-specific fork that shipped with the phone. When a manufacturer’s downstream kernel goes unsupported, it is frozen at the last update and never patched again. The mainline Linux kernel, by contrast, continues to receive security fixes through the normal kernel release process for as long as kernel maintainers support the hardware — which, for well-established ARM SoC platforms, can extend for well over a decade.
This distinction matters to the reader in a concrete way: a device running postmarketOS on the mainline kernel is a device that continues to receive security patches. A device running a…
