Basically tech details are not bad or good - they just details.
When I buy expensive HW and there are some HW malfunction - I would like to know about it because:
I want to know if I need to worry that I might have the problem
I need to buy new phone and I would prefer to buy revision where it was fixed
I would like to know details and if my HW is effected I would like to try to fix the problem before I encounter it
If i have certain problems I would like to know that this is because of HW and not my operator, sim or SW and try to fix everything around coz I'm unaware of the real cause
Bad reviews about Jolla and no explanation or prove it was fixed in any revision - is bad PR.
