Let me give my impressions on some of those things:
Headphone Port: I bought a dedicated DAC to drive my Superlux HD681 for my Desktop. If I turn that DAC up to full I can use those headphones as mini-speakers. Well, let's say with the V I can do the same Also the quality is pretty good, however I can also notice the hissing @pauliunas was mentioning in one of his videos, and I can see that it's getting annoying for a more silent type of music.
Fingerprint: Works really awesomely well. It's blazingly fast if I put my finger on it correctly But I still take 2 times to unlock my OP2 so that might just be me
GPS: Well, my DVT1 had it built in... and I think I've never seen it getting any signal
USB-A charges other devices, the USB-C charges my Switch even when the V is on battery. I don't think that we're supporting charge-during-sleep or however you want to call that tech
Have not seen that at least on my 3 prototypes I had my paws on
I have not seen any noticeable lag during OneNote except 1-2 times but that was when OneNote itself seems to have nearly frozen
Not yet, I think that is on our list and can be pretty easily provided with a software update
Sleep/Wake via pogo-pins works fine, I've not had it work for me in Bluetooth.
Some answers from me, written with the V (and my mechanical keyboard - I can't switch away from that if I'm at home :P)
