Well first of all let's make very clear there is no SIM card holder problem! This is not denying or shoving under the carpet and I will explain why.
Also I really wonder what you need or why you would need the minute details. The only cringeworthy thing in the thread you pointed at is ZoG's behaviour.
Also getting into detail about this gets most likely in the murky legal waters of ODM agreements, NDA's and what not... Not to mention the possibility of this being turned into "Jolla confirms/admits enormous flaw! OMG!" But basically as an intelligent being you could probably already have figured out what it is. But anyway.
So somehow a very small batch of phones got shipped with a faulty SIM holder.
This kind of thing can happen with any product, and is actually very common in the electronics industry. Especially when production gets ramped up for the first time on a new product. First batches always have a few more issues. Well that goes for everything, also cars, fridges, etc... Big manufacturers actually adjust their production and QA based on this type of warranty cases. The exact reasons why this happened I can probably not legally expose, nor am I sure that what I heard is correct. And I maybe have already said too much, I really hope it is not the case (Btw even CTO's have to respect NDA's unlike you stated) Also this is only what I understood of the problem, I was not involved into the details of this, so honestly I am not even the best person to say anything about this. Also not being directly involved is why some things go unanswered since the person who knows might not see the question, and the person who sees it might not know enough to give a valid answer.
Also comparing it to a Toyota recall is wrong. A recall is for a widespread known issue. This was/is just a small set of highly publicized warranty cases. Which is why it took so long to identify and find the cause. We had to wait to get one of those few problematic devices, test it, go to the odm, have the odm test a faulty device, etc... all that takes time.
IMHO saying that we confirmed the issue, found the cause and ask to send in the device for warranty repair is more than enough. Why you think we should need to give you the minute details is beyond me. Unless you have the equipment to fix everything yourself? This said I have a hard time still grasping what you exactly want.
And for clarity. There is (to my understanding) no and never has been a SIM card holder problem. Of course I am sure some paranoiac/troll is going to call this a denial...
There was indeed a mistake made back then. And I personally yelled at a few people that we were doing the wrong thing back then. But then again I hope we learned from it. Aren't we allowed to make mistakes?
It is really hard to do engineering, debugging, QA, customer care and customer relationships all at once. We are people and there are things we are better at than others. And things we have done before and haven't done before. Most of us are engineers and never had to do PR. So that is a new world to us.
And before you say I avoided the fk_lx case. As said earlier I do not want to get involved into that mess.
