fix does not work.

Is that force roaming to Vz? Maybe you started getting spotty Sprint ownwd EVDO coverage. Forcing 3g only could be putting you on Vz towers.

Doesn't EVDO Only disable voice calls?

This would also be a good way to save battery without losing all data connectivity.
3G/EVDO uses a lot of power. If you switch this setting to CDMA only you will force the phone to only use 1x. The data rates will be slower, but acceptable enough for most notifications and light things like facebook.
CDMA - 2G/1X Slower Data greater battery life
EVDO - 3G/EVDO Higher speed data, battery hog.

I dont think it is.
I have my phone set to Home network only. doing this boosted my signal from 1 bar (-90,-100dBm) to a full signal (-65dBM) it clearly says Sprint CDMA EvDo Rev. A in connection status.
Thank you very much =D

Yep that is correct. Just tested it...
Hybrid OR CDMA only are the only options you should choose here folks.
CDMA only WILL produce battery life savings though. Your data will be slower then molasses rolling uphill in December BUT it will be sufficient for emails.
It's a very nice find either way just on that fact alone. Back in the motorola days this was a very popular battery saver mod. Disabling EVDO and forcing it to always be 1X.

hehe.... you are correct sir... going back to old ****ty service again so i can get phone calls

The EVDO radio and CDMA radio are two different radios I believe.
When you put EVDO only you're probably seeing JUST your 3G signal which might appear stronger.
CDMA only you're seeing just your 1x/voice/sms signal.
Hybrid the signal bars I'm sure just average the two out...
That's how I "think!" it works... could be way wrong.

Well at least i tried since sprint is dragging their heels. We need a new radio and quick.

I wouldn't be surprised if a new PRL fixes this... seems to be area specific, I have great signal for the most part...

Also, fixxer, I know you've been having horrid battery life. I'm sure the low signal is causing this as the lower the signal the more power the radio is going to be given to try and maintain the signal.
Try CDMA only and use WiFi whenever you can (also be sure to set WiFi sleep policy to never). 1x uses significantly less power then 3G... although it's to slow to be downloading big apps or loading really complex web pages, it would however be great for general notifications. Give it a shot and let me know if it helps your battery at all!

Hey, it can still work as a temporary solution for some people. I'm close to saying "Dagnabbit, I don't care if I get calls. I want to listen to twit live!" GV notifications should still work, anyway.

Could be a prl but i still think it needs a radio. This phone is set to wcdma when it should be cdma auto prl. Hopefully we get a fix or ota soon. My battery is better today since i flashed a stock rom and kernel. Not great but better.

I gave the CDMA-only option a shot, no incoming phone calls at all. Switched instead to EVDO only, and calls seems to be coming through better in an area where I had maybe 50% success rate for incoming calls when running unmodified. I'll leave it here for awhile, so I know when someone is actually trying to call me.
This is horribly frustrating, I suffered with poor AT&T service for years for the iPhone and never thought I'd be wishing I hadn't changed carriers. I could maybe justify the shoddy call coverage if data was at least fast, but it's not. I'm giving this another week, and going for a return and possibly switching carriers again.

CDMA only setting for calls/texts paired with 4G for data seems to work pretty well.
Since EVDO only mode seems to prevent receiving calls.
True test will be when I get home, 1930's brick building that has been raising hell with calls.

Haven't heard anything about that, have been able to do that if using 4G or WiFi.

It is a limitation with CDMA technology. You can talk and be on 4G or WIFI but not 3G.

I read a discussion about this once before. Basically they said that due to limitations in cdma tech, it most likely won't happen unless the phone has separate transceiver chips.
That's what they said, not what I'm saying, lol

I am moderately surprised this hasn't happened yet. Given that we have a wifi chip, an FM receiver, bluetooth, 3G, 4G...some phones have had FM transceivers as well, NFC, etc....
I am not surprised, however, because bandwidth is very limited...we're not talking back-haul, we're talking actual radio wave space....I'm dying to know what breakthrough will come along to alleviate that.
If anyone wonders why your mobile internet sucks it's oversaturation....not of the back-haul line that connects the cells to the backbone but of the very air itself as allocated. There's only so much physical space in them airs. Too may people, not enough frequencies, bands are too narrow, too many things need their own band.

It isn't a limitation. I used to do this on my Treo 755. Sprint set it up so we can't do this. There are two types of internet packages we can get for our phones and they basically ended the other one. lol.however, not many people knew that. I am getting 2M down and 768up on 3g where I'm at. when my 4g coming? hahaha
But they did it so they could limit what we do.

I think this is the same guy that came on and said the same thing on the last post that got out of hand.
This is real simple:
CDMA Technology has a limitation that doesn't allow talking and data on the same radio. End of story. No, there isn't a way around it.

Exactly why WiMaxx 4G was established, to enable that capability.
GSM is only able to achieve this because they have HSPA for the data side if i'm not mistaken.
Sprints already in the works on switching to LTE 4G, I wonder if they can just make it a hybrid WiMaxx/LTE network and have a radio capable of using either...

So when Sprint switches to LTE, will the current 4G phones work still?

There is a newer version of the CDMA spec that allows it, but Sprint hasn't deployed it. It's unclear if they will, and it's unclear whether existing phones could be upgraded to use it if they did.
For now, it's just like it always has been on all CDMA devices...no 3G data while you're on voice.

No, it is a huge limitation with cdma. Sprint isn't the only one with this limitation.

The tbolt is the only Verizon phone to offer it. It has svdo (?.) Technology. We wont be able to do it with an update.

anyone heard about this

i got a call from my buddy from sprint and he said in 20 days sprint is gonna buy and get verizons 4gLTE
anyone know if this is true or not.
i know that the nexus is getting a update hopefully this week that is suppose to boost 4g and wifi connection. so thats a bit of a hint
what you guys know about this

I have heard that they were going to be using LightSquared possibly. Not sure if that is VZWs LTE provider, but since Sprint uses VZWs 3G towers, I can't see why they won't strike a roaming contract with them again.

An LTE roll out for Sprint will happen.
It's been talked about that Sprint may embrace both LTE and Wimax standards.
However, it's not an instant process and a phone would have to have an LTE radio to use the LTE band.

In 20 days some sort of deal might go down, or they might start some sort of project, but there's no way they can instantly switch and certainly not in such a short timeframe.
IF Sprint drops Clearwire then yes, Wimax would not work with Sprint phones.
It's been suggested that Sprint may go to quadband phones though.
Who knows. I'm not even sure Sprint does, which is part of the problem.

I wouldn't doubt it.
Sounds like a good idea actually.
And it coincides with the idea that Sprint might just run both standards along side CDMA (which would eventually be phased out, eventually.)
Both LTE and Wimax have uses.
Why shouldn't both technologies be used for what they do best?

Both are just different technology standards (well not even standards lol).
Its just like wireless a, b, g or n.
Just different "standards" for wirelessly transfering data.

In 2009, the ITU-R organization specified the IMT-Advanced (International Mobile Telecommunications Advanced) requirements for 4G standards, setting peak speed requirements for 4G service at 100 Mbit/s for high mobility communication (such as from trains and cars) and 1 Gbit/s for low mobility communication (such as pedestrians and stationary users).[1]
http://en.wikipedia.org/wiki/4G
Basically, 1 Gbit/s when not moving, 100mbit/s when moving and VOIP.
Everything runs through data.
Texting, Voice as well.

It has nothing to do with LTE and all to do with the spectrum used by Verizon.
Wimax would be just as "awesome" if at the same frequency.

Both rezound and thunderbolt can do data and voice over 3G cdma as they both have dual 3G radios.

I was just doing some WiFi tethering and I received a phone call... Noticed I was still getting emails. My first thought was that my laptop automatically reconnected to my work's wireless connection. NOPE! I verified again with an outbound call... Data works on the phone and over tether DURING the phone call. Supposedly this was going to be a feature of EVDO Rev. A, but Sprint had not initiated it yet. This is freaking fantastic. I guess our phones started using 3G for voice
Sprint SGSIII blue

Sprint enabled this under their network as part of Sprint Vision. It is basically an advanced 1X data network that allows data while on phone calls. Only the newer phones with certain frequencies support it. Doesn't force us to use 4G or Wi-Fi if we want data and phone calls together. IPhones do not support this unless you're on a GSM network which Sprint isn't. Sprint is CDMA like Verizon.

If the issue suddenly occurred, I think it's one of two issues:
1) AT&T is currently modernizing (upgrading) the cell towers in your area. This should be the case if the issue continues after restarting your device or if it occurs in a specific area.
2) The cell towers are loaded with AT&T users. Yes, all carriers in the US prioritize their branded devices first therefore you will be knocked off the LTE network completely if the cell tower RSSL computer has too many users connected to the same antenna because you are using a non carrier branded device. This should be the case if the issue is intermittent.

It happened, well I noticed it, about 5 hours prior to posting on here. I was rooted on stock 5.0.1, but had been flashing "sweet rom". I ended up having to flash stock via Odin, and start over. There may have been an easier way, but I wanted to make sure that I hadn't permanently lost LTE.
