So, it’s early November now! Fairphone just sent out an apology mail with a YouTube video:
There’s also a 25€ discount code for future purchases in the mail (which I can add to my three codes I got for referring the FP3).
The reason for this latest delay, according to the video, is a “minor audio issue”. At least, I can now go on an extended weekend trip without bothering if my phone would arrive safely…
