Signal strength on this phone seems to be sucky in general.
I picked up my Verizon LTE GN yesterday and have had signal issues with it.
With my Droid X I would get 3 bars of 3G at my house. The GN only gets one.
With my Droid X I could be on my hammock in my backyard, about 20 yards and a couple walls away from my router inside, and I'd have like 50% wifi strength. With my GN I lose wifi connection 20 ft from the router, and that's inside the house.
Signal strength is the worst part of this phone.
