With this update potentially being tied to perhaps even removing patented Qualcomm functionality, anyone else worried that there might be a chance that this update could affect things in some (negative?) way, at least some devices?

"The ruling in China involved two Qualcomm patents. One lets consumers adjust and reformat the size and appearance of photographs. The other manages applications using a touch screen when viewing, navigating and dismissing applications, Qualcomm said."

So, 12.1.2 Beta 1 was build 16D5024a, and final is 16C101. Am I missing something, or shouldn't it be a D series? Or did they in fact do something weird?

I guess the overall question is whether or not addressing things to deal with the disputed items might have some (negative or otherwise) effect when this update is installed.
