Coming from an OG Droid I was used to cradling the phone in my hand with my fingers on the top, bottom and sides of the phone. I've been making calls on my gNex today and people have complained that I keep breaking up. Took a closer look and the mic is on the bottom of the gNex right were my pinky finger normally rests (the OG has it on the front so my fingers never covered it). Guess I'll have to change the way I hold the phone.
