Sorry but the Dealer already verified that all 8 were from different batches .. and actually we were able on the last on to test out idea, that it is not just the transport which may cause issues its actually following thier instructions to remove it from the packaging !!!.. as we were able to replicate the issue on the "virgin" parts quite easily ... again its a 10cent fix ... but what did they miss it .... and that was my point i would expect something simple like this to be picked up and solved BEFORE a client gets their hands on it ... which mens there quality standards are really slipping and going downhill ... they need to maintain an Apple like attention to detail as they are often compared to apple from a design and mindset, and as such they need to focus on the whole experience ... bugs can be fixed ... look at what apple did with the Antenna gate issue ... not hide away and stay the problem can not happen !!
Ill edit a pdf and upload to my DB later to show what the issue is.. and how it could be solved..
