I've been delaying getting it fixed because it'll be a five week turnaround from Samsung support, according to forum posts regarding similar issues. It also sounds like Samsung's support is nightmarish.
Meanwhile, I'm sure if this had happened with my old iPhone 4 (which I'll be using while my GNex is away), I could have gone to the Apple Store about half an hour away and gotten it either replaced on the spot, or at least been able to work with an employee right there to get it sent out instead of having to go through the standard terrible warranty processes. Even if there was no Apple Store near me, I've never heard any complaints about Apple's phone support like I have about other manufacturers.
The point of all of this: while Google obviously won't have the retail support an Apple Store does, by having exclusive call centers regarding only a few devices, they'll be able to make sure their employees are better trained and their phone processes much more streamlined than the manufacturers ever could. In fact, maybe I'll just tough it out with my wifi-less phone until the new call center opens...
