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, which seems to be exclusively Sony¹.
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.
(update) Graphene OS has a list of supported devices
(and it appears they don’t maintain old devices)
Pixel 9 Pro Fold (comet)
Pixel 9 Pro XL (komodo)
Pixel 9 Pro (caiman)
Pixel 9 (tokay)
Pixel 8a (akita)
Pixel 8 Pro (husky)
Pixel 8 (shiba)
Pixel Fold (felix)
Pixel Tablet (tangorpro)
Pixel 7a (lynx)
Pixel 7 Pro (cheetah)
Pixel 7 (panther)
Pixel 6a (bluejay)
Pixel 6 Pro (raven)
Pixel 6 (oriole)
So Graphene’s mission is a bit orthoganol to the mission of Postmarket OS. Perhaps it makes sense for some people to get a Graphene-compatible device then hope they can switch to pmOS when it gets dropped. But I guess that’s not much of a budget plan. Pixel 6+ are likely not going to be dirt cheap on the 2nd-hand market.
¹ Caution about Sony: they are an ALEC member who supports hard-right politics. They were also caught using GNU software in their DRM shit which violated FOSS licensing in a component designed to oppress. Obviously buying a new Sony thing is unethical. But perhaps a 2nd-hand one is fine. It’s still dicey though because the 2nd-hand market still feeds the 1st-hand market and rewards the original consumer. Sometimes it’s clear you’re not buying from an original owner, like someone on the street with a box of 100+ phones.
Current FOSS supported smartphones are mostly not really compatible with BIFL
Firstly, Rooting/ flashing non-manufacturer firmware voids your warranty. A phone without manufacturer support is going to struggle to be BIFL. If you’re able to flash the original ROM back on that protects you some, but if a failure leaves you unable to flash firmware then you’re SOL.
Also, the FOSS OS might be solid but many ports to specific phones are enabled by only a couple of developers doing it on a voluntary basis. You might well find multiple FOSS OS are being maintained by a single person who is really into keeping their phone compatible with multiple FOSS projects. Unless you’re going to be that person, you would want to check that’s not the case, because if that person upgrades you may find yourself without support which again is not BIFL.
The closest you’re going to get is probably something like the Fairphone. They’re designed to be long-term repairable, ethically produced and running FOSS. But they are also far from the cutting edge. Pick your poison.
I just bought an all-metal sewing machine from like the 1960s. Of course the warranty is toast (though it was generous… like 25yrs or something). I would not say it’s not BifL on the basis of warranty expiry. It will likely last the rest of my life which could amount to another 50 yrs.
Most of what I buy outlasts the warranty. Then I push it far beyond what’s expected. But indeed smartphones are such an obsolescence shit-show out of the gate they will be the hardest product to push the lifetime on.
