The deGoogled Fairphone 3 is most likely the first privacy conscious and sustainable phone. It combines a phone that cares for people and planet and an OS and apps that care for your privacy.
It features a removable 3000 mAh rechargeable battery. And in case of an accident, with its replaceable modules, you can repair it your self with a single screwdriver.
If you care about fairer technology, it is an obvious choice.
