Well with the thunderbolt, charge, bionic, a radio fix was able to help with the reception and data connectivity I would assume this would be the same way. Plus the testers already said that 4.1 increases signal strength greatly so I guess we will just have to wait and see.
Testers are full of it. When I had a Gnex wks ago (b4 release) it already had 4.1 on it and the signal is no better then another build pushed out yet. IE i ran 4.0.1,4.0.2,4.0.3, & 4.1 no differece in any of them including the radio updates. And do to this reason I gave it back, its unacceptable for being a flagship device. Data drops, poor signal in general, and terrible battery life just don't cut it for me.
To further add I would not count on updates correcting it entirely. It may get better but it will NEVER be able to be compared to some of the other LTE device out so far. And no i can not go into detail on how, or why i say that. Best i can say is i knew someone involved in the project from the beginning of it being started for VZW and this has been a problem since day one and has yet to get any better. My personal opinion is it is the design internally. whether it is the chip and programming itself or the was the antenna is setup inside the device getting interference from something else I don't know, but at the end of the day its terrible IMO
