I had a Fairphone 2 in Germany (where the next Apple Store was four hours away). I dropped it onto the metal blades of our radiator, which shattered the screen. I was due to go on vacation in two days.

So I express-ordered the replacement screen from Fairphone, which arrived the next day, case closed. (A similar thing happened with a Pixel 4a a few years later, which had to be mailed in, and took a week.)

My wife also had a Fairphone 2, and her headphone jack was a bit flakey. So after a few months we ordered a replacement module, which fixed the problem (for €30!). Afterwards, I emailed Fairphone as this issue had existed from the start. They refunded us the module.

And I also fondly remember the updated camera module they sold for the Fairphone 2.

Alas, these phones are too big for my tastes, which is why I no longer have one.
