Sailfish OS for Sony Xperia 1 II and 5 II

Sailfish OS for Sony Xperia 1 II and 5 II

These release notes cover Sailfish OS for the following devices:

  • Sony Xperia 1 II (XQ-AT51, XQ-AT52)
  • Sony Xperia 5 II (XQ-AS52)


This is the first public release of this port. The port existed before it’s public release for quite long, it was developed along the Xperia 10 III port.
I’m using it ever since then. However the testing, polishing and subsequent release took quite some time because of my personal situation and the work on other items such as the the update discovery service Cosu.

The highlights of this release are:

  • No notable highlights here exceptthat the device works fully except the known issues
    noted below and the issues where community ports don’t have
    the access VoLTE packages used by Jolla’s Sony adaptations.


The devices have the same functionality level as the Xperia 10 III port made by Jolla, except in areas such as VoLTE where public packages are missing or in relation to Sailfish X features which are (currently) unavailable.
Some features such as camera support might be different as for the nature of the difference in platform between the basis of
the two ports (also called boards).

Known issues

  • sonyxperiadev/bug_tracker#756
    When trying to record a video the the camera app freezes and has to be forcefully closed.
    The bug is caused by an issue inside the camera server used by the port or the adaptation camera configuration.
    No workarounds for this issue except to avoid recording videos :confused:.

  • sonyxperiadev/bug_tracker#771
    The recording quality when not using the speakerphone or when calling with the phone to the ear is
    bad that it is hard to hear the user of the device.
    When using the speakerphone the quality of the microphone is slightly better but can
    cause echos.
    A workaround is a wired or wireless headset.

Project Updates

As explained above there’s now a separate changelog for project wide updates which can be found down below:

The changelog file about the project updates can be found down below:


The goal of this project is to port additional Sony devices on top of Jolla’s existing adaptations while staying as close as possible to the existing ports and contributing back to the upstream where possible.

Most of the changes from Jolla ports are adopted in both directions since the issues that one port has usually apply to the sister device of the same generation (e.g. Xperia 10 III → Xperia 1/5 II).
This is the reason why changes from Jolla’s port end up in the changelog for these port,
in many cases because they also affect the specific port but not always.

Where possible changes that were done for this port go back to the Mer-Hybris repositories such as the kernel or droid repositories.

The project is open for anyone that wishes to port additional Sony devices to Sailfish OS. Feel free to suggest new features, provide bug reports or to contribute.
