FP4. Update to the latest Fairphone OS

Fairphone OS version FP4.FP4I.A.175.20221207 is the latest operating system for your Fairphone 4 5G, available for the open market, released on December 19, 2022. It is based on Android 11.

Some carriers might have a slightly different version number due to network optimization.

We strongly recommend running your Fairphone 4 5G (FP4) with the latest version of Fairphone OS. These updates include security fixes and improvements.

See the article FP4. Fairphone OS Release Notes for more details on the different versions. Some carriers might have access to other software versions due to specific network optimizations.

When connected to the internet (via Wi-Fi or Mobile data network), your Fairphone will check daily for updates. If you do not yet see a notification about the last update, follow the instructions below to check your current version.

Your processor performs many operations during an update, so it is normal if your device becomes hot during the procedure. As updating also requires lots of power, to avoid malfunctioning, we recommend plugging your Fairphone into a power socket during the update or having at least an 80% battery charge.

To view which version your phone is running, go to Settings → (scroll down) About phone → (scroll down) Build number.
