Great news seeing Android 15 coming to the now four years old Fairphone 4!
I've run an AOSP based on Android 15 on my Fairphone 4 for a long time, but installing custom OS's on phones is just extremely hard, and seeing @Fairphone being able to fulfill their promise of longevity for their products is just wonderful to see! This is a good sign that you can buy a Fairphone 6 today and expect it to last many years.
