First drop for my current N5 as well (I've had 4
I placed it on the (very slippery) aluminum lid of my MacBook Pro, and put the two on a 2m tall shelf. Having completely forgotten about the phone being there, when I took the laptop back, the phone fell right on the marble floor. Luckily it had the original Google bumper case, and got no visible damage.
Now I'm home and I can't test it, but the most fragile internal component in smartphones is the GPS module AFAIK. I really hope it's not damaged
one of my previous N5s had it damaged after a drop.
