I definitely count Fairphone as such. They build long-lasting android phones from responsibly sources materials. They closely monitor their manufacturing chain, make sure people are paid well, and release updates for many years (with as much software in the open so the community can take over). No new phone every 2 years.
The banger? The phones are fairly modular and serviceable (10/10 ifixit score) and they sell spare parts for years even after they stopped selling them. Moreover, they freaking made an upgraded camera module for people to pop into their phones instead of buying new ones.
