Okay, I am an expert on this topic because I went through it with the vision.
1) The serial numbers for the phantom don't match the box, nothing to be worried about
2) the stickers are now applied by default, this is addressed in DJI's official unboxing video, red stickers applied by default
3) the transmitter now 2 beeps by default but there is some question if it is truly in the correct mode. You can install the RC system assistant and choose this mode in software so it is double confirmed. Some say this doesn't matter, it's either or. Some say you need to have the pot done (comes by default it seems) AND the software switch.
Hope this helps save people some time / worry!
