This phone is driving me nuts.
I have been missing lots of calls and recently
tracked it down to when my data is running it will send all my calls
to voice mail.
All other phones I've own will cut data and accept the call.
Is there a settings I'm missing or is this how the captivate work?
Does the captivate have DDTM/DOTM? If so is there a way to turn it off?
Anyone?

While on EDGE, you can only do voice OR data at any given moment. On W-CDMA (3g), you can do BOTH voice and data simultaneously.
If you find your experience differing from that behavior, there is probably something wrong with your current ROM/Radio/Kernel.

I understand That I can only do one at a time on EDGE, which is fine but shouldn't voice come first? The data should get cut so the phone can be use as a phone IMO.
I have stock ROM 2.1-update1 JF6

Is there a certain ROM/Radio/Kernel I should be looking for?
I have had much "cheaper" phone cut data for voice calls. It's my conclusion that Android is not 2G friendly as I've read other
Android devices with similar problems. Some can be solved with DDTM turned off. No such luck with the Capti.
Never bothered to look this up and can't find any info on AT&T ...

Lte is just for data. 2g/3g is data and voice.

At some point when ATT has migrated all of their coverage to LTE capability the network will switch to LTE for voice. Neither ATT or Verizon use LTE for voice calls yet.
Likely within a decade they will turn off their traditional TDMA based GSM voice network altogether and everything will be on their LTE spectrum.

I'm wondering if they'll throttle LTE during phone calls as well. Hmmmmm
pretty sure they only use gsm for calls, as people without data plans that have smartphones (dont know why they do that ) still make calls and text, just cant access teh interwebz

No you didn't get it. Even without LTE they slow down any connection when on a phone call to save bandwidth. You can be getting 6 mbps down and then make a phone call and barely hit one and the upload is like 0.00mbps.
Test it out. Immsuremit will be like that once LTE is voice enabled.

The current deployments of LTE are based on the LTE Release 8 with LTE used for data and 3GPP/3GPP2 (i.e. GSM/UMTS/CDMA/EVDO) for voice.
This will all change when the carriers move to the VoLTE (Voice over LTE), which is most likely a few years away.

Yes, from what I understand, there is no standard yet for Voice over LTE, the various stakeholders are still working this out, and its still a long ways away.
So for the present time (and near future), LTE is data only (and no voice) on all carriers.

I wasn't agreeing or disagreeing. I was stating something entirely different from the OP.
Its not widely known that AT&T throttles all data speeds during calls and I was being sarcastic by adding that once you can do LTE over voice, they'll throttle that too during calls only.
Run a speedtest next time your on the phone and you'll see. Doesn't matter what data plan you have, they throttle all data speeds during calls.

Agreed, I told At&t that i wanted to cancel my service because Im paying for hotspot and its shif during calls. I was never told this before signing up for service. Im upset because hspa+ is enough for my needs and will work during calls but they had to go and throttle the service!

The standard is pretty clear.
You have 3 options for voice under LTE (as of Rel8):
VoLTE - IMS VoIP using AMR
CS (circuit switched) Fallback - basically have the phone camp in the LTE network, and fallback to 3GPP/3GPP2 only in the case of voice calls
SVLTE (Simultaneous Voice and LTE) - the scenario I already described and launched with most NA carriers
The reason for the delay in VoLTE deployment is the difficulty (and cost) in implementation. VZW, AT&T, etc. would probably want to recoup investments in the 3G network already in place before they spend more for VoLTE. At some point in the future, recovering air spectrum from the 3G band is going to be a higher priority than re-using the deployed 3G network, and that's when we'll see more VoLTE movement.
Symptom: I just upgrade from iphone 4s to Galaxy S4, after about a month use, I missed 4 calls from my friends. The phone did not ring at all, and there was no missed call in the log. This is a very serious problem. someone say she almost broke up with her bf just because of this, :laugh:
Solution:For now I found the solution is to turn off the LTE by go to setting=>Connections=>More networks=>Mobile networks=>Network mode and then choose "GSM/WCDMA". Then you will not miss a call.
Compromise: your data speed is reduced to 4G HSAP+. But if you have 200MB plan and only receive emails like me it does not matter(poor solution for people who has unlimited or 2gb+ data plan), plus by using 4G HSAP+ instead of 4G LTE you get better battary life.
Explaination: I lives in Pullman WA where we have LTE here. Some of my friends using a LTE capable phone (iphone 5, other GS4, nokia 920) also met this problem sometimes (this happens totally random or say I cannot conclude a situation when this will happen). The general idea is that LTE can only handle data transfer but not voicecalls (you can make a call with the LTE on and you will see that your phone swith from LTE to 4G), so if you are using the LTE network and your phone is connected to wifi (at this time your phone is using wifi data not LTE and then you are not connected to the tower at all, this is my guess, I am ME engineer not a communication engineer) and it's on sleep mode (these situations are my assumption) you may miss the phone call. But when you wake up your phone and ask your friends to make test call. you will receive the call.
If you read this post, many people with GS3 has this problem before:

and with iphone 5:

and their solution is to turn off the LTE through a complicated process(we have such function build in the phone, :laugh,
I put this here to help people who has the same problem, but I also wish ATT can fix this problem ASAP because we are paying for LTE speed. So if you have the same problem with your LTE phone please leave a post here and this could arrise the attention.

Yes, they give me a new sim and my old sim stop working after they activate the new sim. But I put that new sim into the iphone 4s first before I put it into the GS4, Will this cause the problem? Do I need to ask them to issue me a new sim?
Thanks for the reply
Probably not. If you got a new LTE sim then that should not be the problem.

so you never have your DSL or cable internet down? Samething with LTE network, the lte tower is down. nothing to do with what phone you using!
It takes att about a week to fix it when they received enought complains! that happens in my case, when you call them to report LTE network tower is down, they think you a idiot! Telling or guiding you how to setup your phone! There's nothing wrong with your phone! The lte tower is down!

Everyone would be dropping calls/texts in your scenario but that's not what this is about.
My wife's phone misses calls/texts randomly while moving and connecting to different towers over a 140 mile radius, she has a GS4. Now here's the part that makes your statement dumb. While this is going on, I receive calls/texts perfectly fine on a GS5 sitting right next to her the whole time.
It's a device issue, not a network issue. Something so simple normal monkeys can figure out.

Yea I had it for a week and realized it was garbage here in California, couldn't get anything over 2Mbps in 4G areas. Finally gave up when I tried downloading an app and it said estimated time remaining was 32 hours. Bought the 32GB from the play store plus the $30 T-Mo prepaid SIM and haven't looked back.
The nexus 5 and sprint aren't bad(where I live your results may vary) all you need beforehand is a sprint Sim card for activation. Just pop it in and reboot. That's it
sent from my HAMMERHEAD neXus
You shouldn't have any issues but I'd recommend taking a trip to a corporate store to get it activated. The one trip up they had getting it activated involved omitting the first digit of the IMEI number in their activation system so if theyre having issues, have them look in to that.
Also, make sure they have micro SIM cards in stock before you go in with your phone else you might need to wait for them to order one.
Haven't had issues with fallback, but YMMV.

I have problems using my Nexus 5 on Sprint. If I leave it on LTE, when a phone call comes in, it does not allow me to answer the call, and then the phone locks up, requiring a forced shutdown and subsequent restart in order to use the phone. So I can only use it in forced 3G /CDMA mode for daily use. I sometimes manually switch it to LTE on occasion, but again, only when I am not expecting calls. Yes, it sucks.
Before you go to sprint Google about them, or go read comments on their Facebook, YouTube, or just all over. Their lte is slower than other carriers by close to 10mbps, spotty, and inconsistent. 3g is pretty much dialup, and calls drop all over. I used to have them through my company for years in 3 states, I ended up paying for my own service just so I could enjoy decent performance.

Like all services, depends on where you live. I've been all over the country and haven't had a problem. In NY I'm getting great speeds at a great price. Once you get over 20mbps, it doesn't make too much of a difference for mobile data. They're also rolling out their LTE network pretty aggressively in a lot of areas and have major money behind them now

eCSFB is the problem. The phone, when in LTE mode, fails to give up access to LTE, forcing the phone to remain in LTE, and when a call comes in, no matter how many swipes you make, the phone app cannot force the phone to answer the phone. The Phone app locks up the phone, forcing a reboot to get out of the locked state. Once they start Spark in this area, and they send out an update, this issue will go away, but in the meantime, people at least in the DC area, will have issues.

I think its more of a case of interpretation. If you cannot physically answer the phone, because it the app locks up because the LTE connection will not release, then it may be viewed as the calls not coming through.
Tmobile customer here and wondering why when I take a call does my signal go from lte blazing speeds to H signal and 10 x's slower data speeds,is this a Tmobile thing or a Nexus thing?thanks
It's an everything thing. When ever you take a call data drops from lte to h. That's why they're development volte.

Which carrier? It may be VoLTE. Or the iP6 may come with dual radios. Keep in mind the N5 only has a single radio, so if you get a call it downgrades to H. Most carriers use an implementation of VoLTE that doesn't work with the N5. H+ is going to be slower than LTE and you may be in an area that they may not have DC-HSPA but just HSPA because of the amount of spectrum. Plus you have to have the overhead of transferring the voice over data.
You could always forward your calls to Google Voice and use Hangouts. Just sayin.
