My house has/does get horrible reception, however verizon is the best of all the cell carriers for reception at my house. On my OG droid i got signal everywhere BUT my bedroom for data. Phone had to be by a window to get a signal in there. With the iphone 4 my 3g signal was solid. With the Gnex my 4g is solid unless I move the phone to the absolute interiormost wall. And speeds are still blazing fast. 15-20mbps with -100 to -110dbm signal.
At my girlfriends house, I'm right under a tower, 5 bars of signal, and have seen download speeds as high as 45mbps with uploads in the high 30's.
At my office, which is in another rough area for signal, inside a metal building, my signal is again in the -95 to -110 dbm range. My OG droid got no reception here, the iphone got no voice reception here. The gnex gets 2 bars of 4g and download speeds of 10-12 mbps.
My home internet from AT&T is 12mbps but only links at 9mbps. Our office internet is 4 bonded T1's (6mbps top throughput shared by 10-15 users). I'd say the 4g is a winner
I have only had 1 dropped call on the gnex, I CONSTANTLY dropped calls on the OG droid.
Your mileage may vary, however right now I have no reason to complain at all. As far as taking a rezound or razr over the gnex for a slightly better signal, I'll pass... Not to start a flame war here but the razr is ergonomically challenged and has a smaller screen. Its also not a GED. The rezound has a snapdragon and a smaller screen. It too, is not a GED. I wanted a phone that would rival/surpass the OG Droid in developer activity, and in the gnex I have met that desire with flying colors and the phone has only been released for a month. I do not believe that razr and the rezound combined will offer 1/4 of the dev activity
or lifecycle support from the manufacturer that the gnex will receive.
TL;DR if you have dropped calls, dont want to do the baseband update, or just have a flake of a device, try exchanging it first before getting a different phone.
