@JDee-Intl Ideally, you have to flash the latest Android 13 from their site. Fairphone OS is Android so they're the same. Latest Android 14 would also work however when I tried that on mine, Fingerprint wasn't working. I'm not sure if that's the exact reason though. Maybe you can try it yourself see if it's the same
In any case, Android 13 is still recommended to avoid issues that is not consistent with other people.
Also, this isn't the right thread for this
