Kind of irrelevant given this is a Samsung forum. Wherever it comes from, any update should be viewed with caution after what KK did to the GN3.
As I indicated in an earlier followup to that post, it was only provided in evidence to the fact that an earlier poster may have been 'jumping the gun' in blaming Google for a faulty update. I certainly don't want to give the impression that I'm bashing Samsung or their products - I actually like a number of the things they've done for the industry.
And to point, it's generally prudent to view any update from anyone with caution. For my part, I'd rather delay that instant gratification of an updated OS a few days to make sure that it's not causing massive headaches to others, first.
I will just leave it at that for others to figure out where the problem lies.
You order a salad at a restaurant. The chef prepares it, the waiter brings it out. Ravenous, you dive in. A few bites later you notice a hair lying across a leaf of lettuce in the corner.
Do you immediately presume the chef must be to blame, or consider the possibility that anyone who has taken possession and control of that plate since it left the chef's hands might alternatively be responsible.
That's my whole point - I'm not trying to absolve Google or to accuse Samsung, but to point out that the reverse, which was the implied thrust of your initial post, is equally ill-advised.
