@rachaelspooky I can afford a new one and my current one is also six years old and has problems with battery, touchscreen, cameras, microphones, charging connector, etc., so I really should replace it.
But it has an IR blaster and desktop mode, which most phones don't have anymore. Fairphone is nice, but hasn't qi charging and is expensive; there isn't really a marked for cheap, used fairphones.
At least, 2027 kind of replaceable batteries should come back for all models.
