My wife seems to have the strangest problem, when she is on the phone she doesnt seem to be able to use data on her note 4. Has anyone else had this issue, she is running NK4
That's normal

SvDo = Simultaneous voice and data. Aka 3G data while on a voice call.
SvLTE = Simultaneous LTE data with voice.
Both of these were scrapped in favor of Triband LTE. I'd say it's a fair trade off but the only time you'll be able to use voice and data at the same time is when you're on WiFi.

No its not as my other 4 x Note 4s can all use data while in call. only thing i have noticed is that hers i made in vietnam and all others (black) are korea
have you checked the exact model number?
there are several different models, and some may very well have communication features others don't have.

EXACT same, one is white and all others are black. They are all on same network running same modem and rom yet this white one refuses to send data while in call.
the 4G/LTE drops to H+ in call which is right, out of hte three i have in front of me now, 1 works perfectly while in call, data and voice, another black one works fine too just a little slower than the other. The white phone just doesnt use any data what soever while in call.
Modem the same etc.
I can always cheat and use wifi but i know this will work 100% i am just baffled as to why this 1 white phone acts differently to the other 2 black ones.

Ok. The other ones have you tried to actually browse the internet while on call?
Cause to me N910c what happens to yours is absolutely normal.
Yes, my wife spotted it as i took it for granted you could surf the web, chat on whatsapp etc while on the phone as i have never had a phone which you cant do it. So after looking at hers which is setup the same hers just hits a brick wall. unable to use the internet etc all messages and data just queue up until she is off the call and it goes through.
Another phone works but is very slow but the main one i use can browse the net while on call without any issues at all. All are on the same network too.
I checked all the settings and they all appear to be the same.
I seem to be able to surf the web etc on older phones such as the s4, s5, i havent tried the z2.
After looking into it i do not see how it is possible because i donot think lte supports this but my phone drops of 4g to h+ or 3g during call

I've got a T-mobile UK touch plus.
Currently, if I am using the data connection then all incoming voice calls are being sent to voicemail. This occurs with a GSM connection, which is part of the spec and is fine, but also with the 3G connection, which should allow the incoming voice call through. I have spoken to t-mobile and they acknowledge this problem and say they are working to fix it.
Is it likely there will be a fix for this? Is there a radio ROM already available that fixes the issue?
Sorry if this has already been covered - I searched with a pretty wide variety of terms and didn't find anything conclusive.
I have the same phone, same network... and it still rings while i have the "3g connected" symbol (3g with two arrows pointing left and right) showing.
Havent tried while connected to GPRS cuz im not sure how to force it into G mode while im near a phone.
Sorry, I should have been clearer - the phone will ring with an unused 3G connection, but not when data is actually being sent/received. This is the behaviour you would expect from GSM, but the 3G spec should allow voice calls through regardless of data - my Vodafone v1605 has no problem with this. T-mobile say it is the device not the network, I just wonder how likely I am to get a fix for this? It could be a problem with activesync using the data connection quite frequently.
A good way to test it is with google maps, or something that will maintain a constant connection, then call your phone. 3G should put the call through, but it will be rejected to voicemail instead.
FYI to put into GSM mode;
Settings>Phone>Band>Set top option to GSM, leave bottom on Auto
same problem here. but i only expreienced that randomly
i know that gprs can not handle data and voice. but 3g should, right?
Yes, 3G should be able to run voice and data streams simultaneously without any problems. I'm surprised there is not more interest in this because it seems to be a pretty major problem with the device if you cannot receive calls while browsing or otherwise using the data connection.
Me too
I experienced this too. I have an direct HTC Touch dual rather than the t-mobile branded version but I'm using a t-mobile sim. I use Exchange Activesync and am missing calls all the time.
fwiw, i experience the same with a Nokia e61 on 3-AT network with exchange active.
It seems that T-mobile have fixed their network today to allow calls while using data. Bonus.
I have TMo tab with att sim. Done everything like flash, carrier unlock, root, modemswitch succesfully. I was just checking what happens when i am watching online stream video or surf web but i when i called from home phone tab is going to voice message, no rings on tab. But with wifi i can surf, watch videos and am able to receive calls. Any solutions?

That's because you can't!
EDGE is 2G, and on 2G you don't get simultaneous voice and data.
If you are connected via 3G, you should be able to do it.
Regards,
Dave
BTW, that T-Mo Tab doesn't support AT&T 3G frequencies normally, and I don't know if it has a soft radio to allow for flashing that kind of support or if it's still a "hard" radio like most phones and devices are.

It is a hardware limitation. T-mo tab=t-mo frequencies and no rom or modem flash or settings can change that. So EDGE will be the fastest cellular speed you can get. And no simultanious data/voice.
Ok I hope someone fix that edge issue. It would have been better that i had bought AT&T tab because of voice and 3G.
...so why did you buy thr t-mo version? This part lost me.

It isn't an EDGE "issue" because it simply isn't possible under EDGE!

First of all, it IS an issue. Agreed, you can't do both data and voice while on Edge. However, what happens is that if you are surfing on Edge (data) and you receive a call, your data connection drops off and allows the voice connection to take control!
pat123 but i did roto's 2g modem update. Do you know 2g and data works together?

Still not an issue, because that is under the carriers control to decide whether or not to prioritise voice or data. If you are on a network that supports NOM1, when an incoming call is received the *network* suspends your data connection to allow your call through. If however, you are on a NOM2 network, this does not happen, and no amount of ROM flashing or tweaking is going to make the slightest difference.
The point is that unless you are on a NOM1 network, there is nothing you can do about it from your phone!

Dave
The technical term is network capability. That network is older than android.
Thanks all got it
hello,

kernel Version : 3.4.0
Build Number :KOT491.D80220a

and each time i'm having a phone call, i'm loosing the Data Connection (3G or 3G+ or Edge )
What would you recommend to fix this (annoying because i can't use waze for example while having a phone call with bluetooth in my car)

Err .. That's normal, and I'm pretty sure it happens with almost all phones and network providers. Your Data Connection will cut out if you make or receive a phone call. Nohting to do with your phone. Use wifi if you want to maintain a connection.

I think any phone with 2 radios can do it just fine. I'm not sure I've tried with the g2, but my gnex and even thunderbolt could, both on vzw. att phones had this ability for years before lte (and the second radio it required) provided it for Verizon. att even ran iPhone commercials pointing this out, since the 3g vzw iPhone only had one radio and couldn't talk and use data simultaneously.

Yeah I agree, a second radio would be required .. which could be why it worked with your Sensation. Unfortunately I don't think any phones over here in the UK have 2 radios as I have had this issues wih ALL of my phones. It's the norm over here.

I believe, but may be mistaken, that the VZW, ATT, and TMo flavors all have 2 radios while the Sprint G2 does not, as their new Spark network combines voice and data onto one radio. This is what I've gathered from reading other forums but have no concrete proof. I believe I once talked on my G2 while using the GPS when driving, which would obviously require data.
What provider is the OP on? Looks like he has a D802, which is the INT model, right?
...this is normal behavior but only in 2G (Edge)...

It is normal in 2G (GPRS or EDGE) to loose data connection during a call...this is the GSM standard...3G is a different standard, it supposed to keep the data connection during a call - voice data is CS (circuit switch, a GSM stadard call), data connection is PS (packet switch, different circuit in phone).
All 3G phones have similar build so CS and PS are completely separate - if you are still losing data connection during a call could be a network issue, not a phone issue.
In 4G is a different situation, at least for the moment - this is still in development, the voice is still in 2G or 3G, not in 4G.

Sprints LTE on phones prior to tri-band had no issues with simultaneous data/calls. The implementation of these tri-band phones has changed the protocol used. They now use CSFB (circuit switched fallback) and this requires the phone to fallback from LTE when a call is made or received. This prevents any data to transmit during a call.

No it did not. Have two sensation lying in front of me. One with stock and one running Vipers. U du have working WiFi during call. So do g2

I know, I red about on the net - as I am living in Europe I don't have this problem - from the begining the European providers used CSFB and eCSFB (they are trying now to develop VoLTE, this is the next step) - I was talking about VOLDOR issue - he mentioned about some problems in 2G and 3G, not in LTE...on another hand he has a GSM+LTE version of the phone, not CDMA+LTE (Sprint) - Sofware Version : D80220a-HKG-XX (Hong Kong - http://www.lg.com/hk_en/mobile-phones/lg-D802)
Sorry, but i'm still a bit lost : Am i having the issue because i have an Hong Kong Version of the phone ? is it an hardware limitation ? Should i try a Europeean ROM Version (i'm living in France, and without changing of provider it was working on my previous HTC Sensation)
I have this issue too. Works fine on my HTC One M7, but when I use the simcard in the verizon G2, no data.
I used LTE Discovery - turns out that when you're connected the LTE and call out, the G2 starts the call on 2G. My M7 starts the call on 3G or H, so I have data and voice on my M7. I am looking for a way to fix this too...

Recently my s7 edge appears turned off when people try to call me. Then after a while i get the text saying someone tried to call me but the phone was off (but it was actually on). No problem making calls. It's not that you can represent it, it is totally random and not too frequent but enough to annoy me.

This used to happen to me too, i think it was because of carrier and coverage, especially when 4G signal is low.
What i found helpful is keeping my device on 2G only when on Wi-Fi or don't need high speed cellular data.
I use this app to have a shortcut of 2G/3G/4G switch in notification panel, makes switching between 2G and 4G easier.

Thing is i NEVER use mobile data, it is off all the time and the apn list is empty (no profiles), i only connect using wifi. Does that still have an effect ?

It doesn't matter if you never use data, device can still connect to 3G or 4G (though in some cases an APN may be needed to connect to 4G, that depends on carrier). In your case, since you never use cellular data, you can safely set your device to 2G only. With 2G you will have better signal for sure, and it's less likely to have missed incoming calls.

After unlocking my bootloader and rooting my phone I went ahead and activated it on United States sub carrier Cricket. Since activating I've found the cellular reception to be abysmal, especially compared to my previous phone and my friends phone both on the same network. Ive yet to see it drop below mid 90s dBm and is generally around 110. So almost always it is one bar or less on the x compact where my old phone and my friends phone have full bars in the same spot. I'm on marshmallow build number 34.1.A. 1.198, baseband 8976-8976.gen.prodq-00005 02816.

I could be wrong here but doesn't Cricket operate off Sprint ? If so you have a CDMA network trying to pair with a GSM phone. Basically if my guess is right then you bought a phone that is not compatible with the radio signals Cricket is using.
P.S. Ok I just did a quick check and it seems Cricket is or has (didnt read much) switched to ATT GSM. Granted I don't know if that process is complete though since I don't really follow Cricket. So I am guessing either you need a new updated sim card and/or your APN settings are not up to date. Go into phone settings, More, Mobile Networks and then click Access Point Names. See if what you have there matches with what Cricket says it should be.
I do not think the standby signal represents the whole picture, at least not on my phone. It is always around 2 out of 5 bars. At first I was a bit worried/puzzled, but I realized it is only untill I make or receive a call then the signal goes to full 5/5 bars. I assume it's power saving it makes sense. I never missed a call or had trouble making one since I got the phone back in sep 2016 ie. it never totally lost signal in standby, and since the signal went to full strength when in a call I never investigated it further, as said it seems like its just lowering the standby power untill a call is made or comes in. I had another carrier the first couple of months and the behaviour was/is the same on both. Not saying that the carrier/phone also can play a role in this. Idk other from my own experience which do not bring any problems.

Cricket is owned by AT&T. It is, essentially, AT&T with some speed and roaming caveats.
APN settings would not affect signal strength.

Your signal may go up to 5/5 bars because you're switching from LTE to 4G to complete the call, and your 4G strength is stronger than your LTE strength.
