There is now a European standard for measuring how easy it is to repair stuff
I had a Fairphone  1 once. It fell on the floor and the display cracked. I was able to order a replacement screen and replace the cracked screen in about 2 hours thanks to iFixit [1]. And I have no idea of electronics whatsoever!This is remarkable but unfortunately not sustainable. The manufacturer needs to enable repairs, provide howto's and he needs to guarantee, that you can buy those replacement parts.At some point after Fairphone 2 was released, which was priced a lot higher, I was unable to download newer android versions even though that was promised. It was just too complex for them provide an update.That's the sad truth: Support for old hardware diverts manpower from more lucrative things in the business: Creating and selling new phones.[1] https://www.ifixit.com/Device/Fairphone_1
