Hardware far outlasts software in the smartphone world, due to aggressive chronic designed obsolescence by market abusing monopolies. So I will never buy a new smartphone - don’t want to feed those scumbags. I am however willing to buy used smartphones on the 2nd-hand market if they can be liberated. Of course it’s still only marginally BifL even if you don’t have demanding needs.
Has anyone gone down this path? My temptation is to find a phone that is simultaneously supported by 2 or 3 different FOSS OS projects. So if it falls out of maintence on one platform it’s not the end. The Postmarket OS (pmOS) page has a full list and a short list. The short list apparently covers devices that are actively maintained and up to date, which are also listed here. Then phones on that shortlist can be cross-referenced with the LineageOS list or the Sailfish list.
So many FOSS phone platforms seem to come and go I’ve not kept up on it. What others are worth considering? It looks like the Replicant device list hasn’t changed much.
It’s too early to be certain, but I’ve got high hopes for the future of the SHIFT 6mq.
I believe it has mainline linux support, or it is being worked on, which will be important for ongoing OS upgrades. Otherwise they have a similar philosophy to Fairphone with an important difference; SHIFT wants you to be able to upgrade their phones, not just repair them. I don’t think this has been realistically tested yet, but the successor SHIFTPHONE 8 is coming out imminently, and I think we should start to see pretty soon if any of the new modules can be installed on the older model.
I’ve actually got the SHIFTPHONE 8 coming myself, because I got spooked by places turning off 3G already and wanted to “future proof” with 5G, but otherwise would have preferred the 6mq.
The one caveat is that SHIFT is a very small company, which could mean risk for long term support.
