I haven't noticed until know that the SGN from Verizon shuts off 3g/lte while making calls.
Does this have something to do with ATTs contract with Google and Samsung.
I will leave this thread open as hope that we can resolve this issue. Please post your experiences. If your are not having issues with your SGN from Verizon please post. Thank you

Oh yeah wtf? Right?

Its a limitation of cdma.

OK but why did Verizon tell that me it does do calls and internet at the same time. Two customer reps told me this and one told me its in the manual. I'm going through the manual now

It's the network. Not some under the table contracted agreement.

It should be able to do voice and data anytime you have an LTE signal. On 3g you cannot though. Its a limitation of cdma.

robitron929 · Feb 28, 2012

Yeah Verizon has good towers here in California. Sh..ty service and BS like made me spill my coffee

robitron929 · Feb 28, 2012

Fine could we at least mod that out? I mean that's a load a crap

adrynalyne · Feb 28, 2012

No.

Only LTE can coexist with calls.

robitron929 · Feb 28, 2012

Well what about a lte only switch if that was compiled than it would help right?

No. An LTE only switch would kill the cdma radio which is where the voice is routed on the Nexus.

*blink blink* TRWTF is the above question.

As stated, this is a limitation of CDMA, or at least Verizon's current implementation of CDMA. Every 3G phone exhibits this behavior, as well as LTE phones when out of range of an LTE signal.

There is one exception to the rule. VZW has updated their CDMA towers to allow SVDO which is voice and data over 3G, however the phone has to have a compatible chip set for it to work. The HTC thunderbolt is the only phone I know of that does SVDO when there is no LTE signal

Yeah, that's what's described at the "current implementation" link. As far as I was aware, SVDO hasn't been rolled out yet. Has Verizon already "flipped the switch" on SVDO?

SVDO was ready at launch of the TBolt. There was no press release when it launched tho. I don't think SVDO is going to catch on with VoLTE coming and the power hungry chips is just not q recipe for success

Ah interesting, yeah, I didn't know that. They definitely didn't bother making a big deal out of it. Well, good to know, anyway.

Wow no option at this point

Welcome to CDMA. You can't do simultaneous talk and data over 3G. The only way you can do voice+data is if you're talking on 3G and doing data over LTE. If LTE drops while you're in a call, you have no data.

What are you even talking about? You have the entire technical reason behind your question, and you've been presented with the options (use LTE/WiFi). Alternatively, you can cancel your contract and move to AT&T -- have fun with that.

Well than i m guessing it would be a long shot to implement SVDO into a modded radios package
. Or maybe the hardware's incapable regardless

Dude. It's a hardware limitation. It's like asking if you can download more RAM.
