If you've been looking for a smartphone with a long term software update guarantee from the manufacturer, then the Fairphone 4 might be what you've been waiting for, as outside of being user upgradable in many ways, the company promises Android updates until at least 2025, but possibly as far as to 2027. This is leaps and bounds ahead of the competition and although the Fairphone 4 isn't what you'd call a cutting edge phone, it does have some unique competitive advantages.

Fairphone is a company that started out with a vision of delivering not only user repairable and upgradeable phones, to reduce electronics waste, but also to use more sustainable and more fairly sourced materials. In addition to this, the company claims to pay its factory workers better and to improve their working conditions.
