On the vibrant theres an option to run on I think what is called edge network, I could be wrong, does verizon have such a network to run off of my buddies vibrant's batteries life is unreal...well aolt better than mine.???
Thx

Edge is the 2g network, when you drop a 3g signal your phone gets stuck on Verizon's version of it... I guess it would improve battery life but don't try to any browsing on it...

Edge is a type of GSM network, Verizon uses CDMA, so no, you can't use EDGE.
The equivalent to EDGE in Verizon would be the 1X data connection, as opposed to the 3G (EVDO) connection. I know we can disable mobile data with Froyo, but I don't think there's any way (without some kind of hack) to force the phone to always use a 1X data connection.

It's somewhere in the hidden menus.
GSM phones, in general, get much better battery life. It has to do with the network. Coverage vs Battery life it's a toss up
Have we received a clear answer on how this works? Has anyone else noticed that when you loose 4g signal while on a call that the call will drop?

i know this is gonna sound mean but it makes sense. if u lose 4g its not a smooth transition. so until it reconnects to either 3g or 4g u tech dont have any service
Unfortunately they are right. There needs to be a better setup as anything up to 3G runs on the same CDMA radio, so therefor it switches and forces a dropped call. 4g is a separate card and works on it's own. Until there is a way to get "just" calling and 4g (aka turning 1X 2g, and 3g off but not 4g) it will continue to do that. I assume custom ROMs will do this in time, but as of the moment it's a known issue that it happens. Sorry to hear it causes you and so many others troubles.

well.....you could go into that secret menu and just enable LTE radio. i dont remember what the code was tho
Your phone calls do not go through the 4G network so that actually would make no sense at all... Your phone routes calls through the standard radio all all data through the 4G radio (if available). If you do not have 4G coverage, the both voice and data are carried on the standard 3g signal. This is Verizon's first simultaneous data and voice over 3g (yes, cdma data and voice) and there are known issues with the tech right now. However these issues have zero to do with any phone using 4G for data while you're on a call. Hope that helps clarify.

So why is the 4g signal loss causing dropped calls?

That's what I'm trying to figure out. Unless it's poorly programmed, it should maintain the voice connection as that's over 1x and independent of LTE.

It's most likely the same problem that Pantech UML290 users are experiencing when dropping from 4G to 3G, and both devices are using the exact same Qualcomm MDM9600 chip. If you look at the Engineering Mode when the drop from 4G happens, your phone doesn't just fall back to 3G, but it actually lose the connectivity for a few seconds and then "redials" back into the data connection.
I hope they fix this real soon.
When you lose 4g, the data tries to resume on 3g, and since no 3g and calls at the some time, you get data on 3g and dropped call

That's incorrect.
you have to have CDMA service for a voice call. EVDO alone will not allow a voice call, LTE alone will not allow a voice call. you should be able to lose 3g and keep your call going, and you should be able to lose 4g and keep your call going.
Maybe that's their way of preventing talking while driving. lol.

So your saying I can make a call, and have 3g? Cause what I described happens on my phone. It resumes data, and kicks my call.

You should be able to use data and voice at the same time on 3G.
It happens because both radios power down to meet SAR requirements. Two radios at full power = too much radiation

This is why we have brave hackers on jobs like this ob. Not sure if it'll happen or get widespread, but I'm sure someone is working on it/done it.
I don't see how that can be true. What does Verizon say?

SVDO uses two transmitters simultaneously for voice+data over 3g. EVO has been using 4g+voice over CDMA for a long time.
look at the last couple pages of this document
http://www.qualcomm.com/common/documents/articles/1X_Advanced_Benefits_050509.pdf
I don't know if simultaneous voice+data over 3g is only available where verizon has 1x advanced or not. since SVDO only requires the handset to have the capability, it would make sense that it could use regular 1x and evdo simultaneously but it would use more spectrum.

It is true.
Verizon says it is a limitation of their network system and that dropped calls will indeed happen when you leave a 4G zone. They have intentionally designed their network not to fall back onto CDMA when 4G is lost, and they hope their customers will be patient while they expand their 4G coverage - which is occurring at a very fast clip. See the following bit from CTIA this week:
However, Verizon has taken the view that it will minimize annoyances for users handing off between LTE and CDMA, because its LTE coverage will be so wide so quickly. For this reason, it is not bothering to invest in systems to support fallback to CDMA for voice calls when a customer moves out of an LTE zone. Although the call will break in this situation, it will be a rare occurrence, insists the cellco. CTO David Small reiterated the point at CTIA, saying: "At the velocity at which we are pushing LTE markets, this becomes a non issue."

But LTE is not handling voice on thunderbolt.

This just started today but my 3G signal is sporatic going from 3G to 1X. Anybody experiencing this? My signal even drops completely.

Let me guess...
You are on an MTD ROM like MIUI CM7, (or some variation of CM7)...
The 3G data dropping out is a problem that comes and goes on many people's phones that can usually be temporarily fixed by toggling Airplane mode or a reboot.
There is no known fix at this time
But... if you are not on an MTD Rom, then disregard my reply
It's also a known fact that the Fascinate has a terrible radio chip. Whether on MTD, modified TouchWiz ROMs or stock, my signal constantly goes from 3G to 1x. Hopefully my wife(Nexus Prime) won't do that.
1st things 1st Love the phone.
Now on to the question.
When im on the phone during a wifi call, if i lose signal by leaving the area, does it automatically switch to the cell service or is the call supposed to drop?
It drops, it can't pick up and drop seamlessly which makes sense... Wifi and the cell tower are totally different. I don't know how it would coordinate that hand off.
It does stuck though, if I make a call in my room and go to the kitchen, I need to be careful to not lose signal

Hey can someone upload the WiFi calling apk? And possibly some libs if needed? I want to try to port this to other variants using T-Mobiles
Hey guys I have a question. I live in a area where there is FAIR 4g coverage. Mostly 3G coverage. Hardly a place I cant get any cell service. Now my Verizon S4 a lot of the time will want to switch over to 1X speeds... very annoying. I dont believe its a phone or ROM issue cause I have had the Droid Charge and the Galaxy SIII and they both done it. Now my question is.. on the S4 is there any way to permantly disable the 1X only? basically I want 3G or 4G only and if i cant get either of those I would rather have no service. 1X seems to make my phones freak out about internet stuff. Like sometimes IMs wont come through and the phone constanty retrys sending the IM... ect.. wasting battery. Anyway to just turn that off? Thanks!

Are you running a custom ROM or stock?
Hyperdrive 8.1
But like I said I dont think its the ROM. But I could be wrong. 2 other phones of mine done the same thing
