I’m using a Fairphone 4, which is 4 years old at this point (October 2021) and I’m still quite happy with it, but I owned the Fairphone 1 and 2 as well.
In terms of software atrophy, they do offer support for your device for 5 years, which is better than most, and because of its open nature, it’s generally well supported by alternatives like Lineage or Calyx, but yeah, I’m still on Android 13. While I still get regular security patches and haven’t really had a need for an upgrade, there’s no denying that the FP4 is behind.
Of course, it’s also easily repairable, supports an SD card and replaceable battery, so that’s a tradeoff I’m happy with.
I’m afraid I have no idea what an RCS is, but maybe that’s a network/region specific thing? I’m in the UK using GiffGaff (O₂) and the phone, SMS, and data works exactly as well as everyone else’s… which is to say perfectly in most places and sporadically on the train due to the dead zones on the route.
