I got my iPhone 7 Plus 256 Gold on Monday 3.10.2016, it's made on week 39 and it has the hissing, buzzing and static noice and sounds near main cameras on the back of the phone, not so loud that I would notice or hear those even when in a dead quiet room, but during video recording the rear mic catches the hissing sounds and it's quite annoying (my 6S Plus is completely silent, even during video recording inside quiet room, I've tested both phones extensively side-by-side now for 5 days)
The sounds are there all the time, if I listen the back of the phone next to my ear, I can hear the static noise even when in Airplane mode or iPhone not doing anything / idling / laying on the table face-down. I remember the old Nokia phones in the 90's had same kind of static noise during phone calls only (radio signal interference to the earpiece), but I've never heard this kind of static noise on a mobile device before.
There was also quite bad yellow tint on the screen at first, and I compared two phones, my year old 6S and 7 Plus. The 6S's screen is pure white and clear, a bit cold colors and 7 Plus was like semi-nightmode-yellow.. But next day it changed, the display went from semi-nightmode-yellow to "a-hint-of-yellow-tint" (is it glue or burn-in or what), but now when both phones are max brightness and next to each other, there is only a minor yellowish tint on the 7 Plus. The quality of the screen is excellent on the 7 Plus, colors are very vibrant and when not compared to 6S the screen looks natural.
Only problem is the annoying static noise in the video recording. I can hear it faintly when speaking with someone on the phone too, but it's so quiet that it doesn't matter (in normal situation it's not noticeable, only in very quiet room).
ATX-motherboards some times have the "coil whine" and it doesn't change even after months of usage, I'm quite sure there is no fix on these iPhones either, except replacing the phone.
