Hi @TimmWa,
in this topic I linked to my picture of my sensors. Below my post is a picture of a FP with working sensors - quite a few are missing.
The Fairphone Angels Program are community members supporting other community members locally - so we can meet up to repair the FP. We do this without any connection to the Fairphone company (because we are THAT nice. 
). As we are normal community members, we receive the same support as any other community member. This way we can share our experience with our local Fairphoners.
Regards
Friederike
