As defined by FP support themselves, if it prevents you from using your phone often it’s quite major. Calling is a major part of a phone, if that doesn’t work, I would call that a major issue. More details here with the impact categorized for each issue: ✏ Known reproducible and reported issues of the Fairphone 4
Weren’t the ghost touches something fixable? By re-attaching the screen properly? Haven’t followed that threat either much.
The camera is a problem everyone can reproduce. People might be okay with the low quality, but the issues described can be reproduced.
Sugarcoating would be like saying “you can still unlock the phone by pin, the fingerprint sensor is a power button, it’s just a convenience”.
I’m trying to steer the discussion more towards what works and what doesn’t. Most replies here stop with that it doesn’t work and should be fixed. But since you don’t reply with links to people that did go further than that, I suppose this threat hasn’t done much to rule out the causes.
So to anyone who would like to find the root cause and get this fixed by giving FP support some more concrete information. 1) Have you tried to re-enroll your fingers a few times, by following the instructions carefully, i.e. scan different parts of your finger. 2) Have you also asked friends to also enroll and see how it works for them?
And lastly, maybe this could be in play?
