Vanity, marketing and buying shit unnecessarily.
I have a Fairphone 3 that I got in January 2020. Its a great device. I want to using it daily for between 5 to 10 years. And I have no doubt it will do that.
Meanwhile my brother has bought 3 Samsung devices in that time. And each one still works fine. He doesn’t need a new phone each time but he will still insist on it.
The camera on the Fairphone 3 is only okay. But there is an upgraded camera module you can buy from Fairphone.
I’m not much of a photographer so it doesn’t bother me. But if you take a lot of pictures, it’s something to keep in mind.
