Wow... Very nice post & research. I do not have a problem atm but I am inpressed with your work.
Please re-post if Samsung's disposition changes.
Just for some perspective, I have been in the electronics business for nearly a decade. Working with microelectronics is something I do on a daily basis.
So, imagine my disappointment when I sent a phone to Samsung for warranty service, only to have them return it with reported water damage!
Since my warranty was voided, I took apart my phone and found...no signs of water intrusion! You can find details in a document I have sent off to Samsung for review: https://dl.dropboxusercontent.com/u/73830636/noteii.htm
What concerns me is that when I contacted them for assistance, all I received was an apology and request that I contact their voice support, which is notorious for being unhelpful and having no escalation procedure.
I'm willing to bet that there are many others like me who have had phones returned with "water damage" but have actually fallen victim to Samsung trying to save a few bucks because they know that people don't have the technical expertise to dispute their claims.
If you have a story similar to mine, I'd like to hear from you. I have a feeling that this happens fairly often, and we would benefit as consumers if we can gather this information into a common knowledge base and raise the issue to Samsung directly.
