End of software updates - short version: Are you willing to install e.g. LineageOS after Fairphone drops software support?

Yes: For all models: support until = in the distant future
FP5: support until = 2031 or later
FP4: support until = 2028 or later
FP3: support until = August 2024, maybe August 2026 or later

End of software support - long version, part 1: Are you willing to install e.g. LineageOS after Fairphone drops software support to get further security updates for the ROM (Android)? This might include another software feature list!

Yes: You can use your phone even after Fairphone drops support quite safely. Since the security support for the hardware drivers will be less or lacking this might be less secure than having the official support.
No: Watch out for the official announcments from Fairphone about stopping software updates for your phone

End of software support - long version, part2: Official announcements about security updates

The official updates end for sure, when Fairphone annouces it, e.g. FP2. They extended more than once the period of official updates.

FP5: software and security updates until 2031 (*We plan at least 5 Android OS version updates after Android 13) The new Fairphone 5. Designed for you. Made fair.
FP4; extended support till 2028 Fairphone 4 | Fairphone
FP3: August 2024 “We aim to support Fairphone 3(+) with security and software upgrades for about 5 years after the first launch date (August 2019).”
