Hi!
Got my screen protector privacy, and I am quite happy with it. The only thing I found silly was that it does not Brin instructions (which kind of does not need) but days to go to the Fairphone.com/gen6-accessories website, which does not have instructions on this accessory 
.
Is it a real problem? Not at all. But still there should be at least a reference to the product.
Well, this definitely became a problem for me. Was ca four years since I installed a protection, I don’t remember which of the two plastic sheets is the one to go on the phone, both have one sticky side… The red sticker had a very small text (at the time I had no other phone or magnifying glass). The official web instruction linked from a QR code on the package was for v4. It had no red sticker at all.
I followed the video, when pulling the sheets apart I put the protective part on the table and applied the wrong (thin) one… I probably put a thumb on a bad place, when realizing this and switched sheet it it was definitely wasted. Tried to clean an reapply in many ways, no chance.
What an unpleasing unboxing. First impression lasts. I made wrong, but I’m mostly worried that quality assurance was this sloppy, leaving a manual out, and at the same time not ensuring a proper online manual or video. And I definitely hope that other guys deal with quality issues regarding phone software and hardware. 
Hi, sorry to hear about your frustrating experience.
Hopefully things could get improved.
I found the website instructions but as you were saying the video tutorial is for FP4.
There were separate instructions for FP6 but did not mention a red sticker, and the images did not load.
