Pinephone with postmarketOS

postmarketOS released the first major stable channel update. This is the release of service pack version 20.05.1 which adds some big improvements. Since Alpine Linux 3.13 was also recently released, this will be the only service pack to be released in the v20.05 series. As reported by the team behind postmarketOS, the next release will be stable version 21.03 based on the new stable version of Alpine.

These are all changes that are picked from the edge channel and have been tested by all our end-users that are running postmarketOS edge on their devices. The point of the stable channel of postmarketOS is to be really stable, but since the release cycle of 6 months roughly for stable builds is quite long in the software world, especially with the rapid development of the PinePhone we decided that it makes sense to make a batch of backports from edge, test those thoroughly and then release that as a service pack as one big update.

As we can read on the postmarketOS website:

Since at this moment the PinePhone is the only device that’s officially supported in the stable channel aside from the qemu virtual devices all the updates are PinePhone and Phosh focussed, as that’s whats shipped on the postmarketOS PinePhone community edition phones.

The major new things in this service pack are:

  • A kernel upgrade to 5.10.4, this is the current LTS version of the kernel and it also includes some major improvements for the PinePhone like the 60Hz display refreshrate patch to make everything a bit smoother.
  • The autofocus firmware for the PinePhone camera is added.
  • The initramfs build system is updated so the GPU driver is available in the initfs. This makes the osk-sdl disk encryption unlocker a lot smoother to use
  • A new version of the Geary e-mail client is added that fits a lot better on phone screens
  • The Phosh stack has been upgraded to 0.7.1, bringing the new pull-down menu with docking options and the swipe-up-to-close gesture in the app overview
  • XMPP support in Chatty
  • A new release of gnome-control-center that has better fitting applets for mobile
  • Telephony should be more stable now due to the addition of eg25-manager

A new build of the stable PinePhone+Phosh release is now also available from the build service. Images can be downloaded at
