Fairphone (Gen. 6) Android 15 source code build

Following up on our previous announcement of The Fairphone (Gen. 6), we’re happy to announce that buildable code (QSSI as of now) for The Fairphone (Gen 6) is now ready to explore.

As always, we publish as much source code as we legally can – keeping transparency and openness which is our core ambition to bring more fairness into our products.

This build includes the updated A15-QSSI code, along with other components licensed under open-source agreements — excluding some third-party apps such as Google Mobile Services — from which users can generate system images and flash them onto their Fairphone 6.

Please note that proprietary components are also excluded that are required for the phone to work. For those we publish a binary blobs package instead.

You can find instructions to download the source tree and to build your own Fairphone 6 software on code.fairphone.com.

We’d love to see what the community creates — feel free to submit patches and contributions via our public Fairphone Gerrit.

Update December 2025: Adding buildable Android 15 target tree

Hello all,

Continuing our Android open-source journey, we’re happy to inform you that the Target tree for FP6 Android 15 is now available. Users can build both trees (QSSI+target) from sources.

The target tree includes Kernel and vendor sources allowing users to build essential boot and vendor images required for booting and running the system.

The target tree is based on Android 14, with additional modifications to support running a QSSI-based Android 15 system. This publicly released target tree excludes certain proprietary components that are required for full device functionality. These are instead provided through a separate binary blobs package.

We have additionally included documentation to help users get started with the build and flashing process on the device on code.fairphone.com

Should I buy a Fairphone 6?

Thank you, GREAT news !!

Are these instructions actually correct?
If I follow the guide on The Fairphone (Gen. 6) - Build Instructions — Fairphone Open Source
I get a lot of sync errors due to non-existent repositories.

I suspect that the manifests are wrong.

I tried to fix the manifest, but other errors appear:

============================================
error: prebuilts/clang/host/linux-x86/soong/Android.bp:21:1: module "soong-clang-prebuilts" already defined
       kernel_platform/prebuilts/clang/host/linux-x86/soong/Android.bp:21:1 <-- previous definition here

#### failed to build some targets (5 seconds) ####

Did you actually try to follow your own guide to build the target?

This is the manifest ‘fixed’

Thanks for reporting this, @TomHa
The issue has now been resolved, please re-sync the code it should work fine.

This normally happens if the RECOMPILE_KERNEL=1 bash kernel_platform/build/android/prepare_vendor.sh fps consolidate step is not executed. Please make sure this is done before running make in target tree.
