Very interesting. This contradicts how Google advertises the service though. They say the transition is seamless. Unless they are playing fast and loose with the definition of seamless, this does not seem to qualify.

According to their website it is expecting signals to slowly get worse and have time to start transitioning before it drops out. A sudden loss of wifi for whatever reason probably confuses it. I would expect walking down the street away from your wifi would cause a smoother tansition.

I also expect those dialer codes are not meant for use during a call, and that is why a transition is queued up.

Have you tried driving from a Sprint deadzone, where you are on TMobile, to a TMobile deadzone where you would have to transition to Sprint? This would show if it can actually transition between the two during a call. Which others seem to say works.

Driving between dead zones of opposite carriers is surprisingly difficult to do - would have been a great test, though!

I did test walking down the street away from Wi-Fi - the transition is much smoother, but I was only able to get it down to about 2 seconds or so. And that was when I turned around and ran back toward Wi-Fi when it started to switch, so that the call remained good on Wi-Fi until it actually cut over.

Yeah, finding the right dead zones would be pretty hard. Especially if you are somewhere with relatively good signal. Would be a very interested in the results.

Disappointed with that 2 seconds though. I was really hoping for smoother. Though I guess that is why they are still invite only. They are still working on the technology. I was leaning towards getting Fi when the new Nexus comes out, but this makes me think it might not be ready yet.

Thanks for all the info.

His premise that switching isn't seamless is based on his use of manual switching codes (something that Google advises against).
