There are a few threads about phones here.
But we don’t have a discussion for repairable phones with a mainstream OS.
Nokia is releasing a repairable phone in the US this month.
the most interesting thing about this phone is that it’s part of HMD’s self-repair line of devices, which means you can find genuine replacement parts, repair tools, and repair guides at iFixit, allowing you to replace batteries, screens, ports, and back covers
There’s also the fairphone. The 5th generation is being prepared for release which could possibly get 8 years of software support.
If you’re from the US: the fairphone 4 will only be available with /e/ OS at the moment, though. Fairphone 4—the repairable, sustainable smartphone—is coming to the US | Ars Technica
Fairphone 5 with de-Googled eOS for UK.
